Chemotherapy for Extracranial Germ Cell Tumours in Paediatric, Adolescent, and Young Adult Patients
Authors: Chen Rong-Long , Lin Han-Ting , Chen Liuh-Yow
Published: December 2022

Extracranial germ cell tumours (GCT) are derived from dysregulated, unipotent to totipotent, primordial germ cells and can arise from heterogeneous sites and occur across a broad age range of patients. Although healthcare professionals in the paediatric and adult medical fields collaborate closely, discrepancies in the staging system and risk-assignment used still exist. Treatment outcomes are worst in adolescent patient groups. Surgical principles have been established for treatment at initial diagnosis and during salvage therapy, as well as for the most difficult circumstances, termed desperation surgery. The development of cisplatin-containing chemotherapy marked the 1st success in GCT treatment, representing one of the major advances in the last 50 years of modern oncology. Nowadays, first-line three-drug chemotherapy regimens use cisplatin, etoposide, and either bleomycin or ifosfamide. Paediatric chemotherapy regimens typically reduce the use of bleomycin or replace cisplatin with carboplatin to decrease the levels of toxic agents in developing children. New targeted chemo-agents have been explored as potential options for refractory and relapsed GCT, as well as non-GCT malignant transformation. Here, the chemotherapy regimens currently used by paediatric and adult oncologists are described. The recent progress in targeted chemo-agents that are being used in the clinic is also discussed. Hopefully, through appropriate delivery of targeted chemo-agents, combined with well-established surgical procedures, the best outcomes of GCT for every age population can be achieved at initial diagnosis and for relapsed/refractory GCT and non-GCT transformation.

Authors: Huertas César S. , Lechuga Laura M.
Published: December 2022

The cancer burden continues to grow with enormous physical, emotional, and financial pressure on individuals, families, communities, and health systems. Early detection and effective treatment are crucial. The analysis of epigenetic biomarkers is presented as an exceptional solution for early cancer diagnosis and personalised treatment design. These brand new biomarkers have initiated a diagnostic revolution because of their predictive capability and reversibility, opening the window for timely diagnostics and personalised medicine. In recent years, the potential of optical biosensors for epigenetic biomarker evaluation has been revealed. Nanotechnology is promoting the appearance of new advanced biosensors able to be integrated in complete lab-on-chip platforms. Lab-on-chip biosensors are offering simplified, cost-effective, and fast results to solve the current diagnostic problems. In this review, we present the advantages offered by the analysis of epigenetic routes in cancer diagnosis and the current advances in optical biosensors for cancer epigenetic analysis, showing how the new biosensor solutions manage to surpass the challenges encountered during the analysis of each epigenetic mechanism.
Modern Indications for Endoscopic Endonasal Surgery
Authors: Lipski Samuel M. , Digonnet Antoine , Dolhen Pierre
Published: December 2022

Endoscopic endonasal surgery has become a standard procedure for functional treatment of benign pathologies. Materials and improved surgeon skills have allowed the number of indications for this approach to increase. We describe some of the main pathologies, including malignancies, that can be treated endoscopically, focussing on the orbital and skull base pathologies. The orbital indications discussed here are dacryocystorhinostomy, orbital decompression, and optic nerve decompression. Advantages of endoscopic surgery for aggressive benign tumours such as inverted papilloma and juvenile nasopharyngeal angiofibroma are described. The skull base pathologies detailed are ethmoid adenocarcinoma and esthesioneuroblastoma for the anterior skull base surgery and endoscopic transsphenoidal approach to the sella for pituitary tumour surgery. Evidence of the safety and efficacy of endoscopic surgery is increasing but there is a lack of randomised long-term studies.

Authors: Gerasimov V. Yu. , Uliyanov A. A. , Snezhko V. A. , Mosar J. , Lavrishev V. A. , Gazeev V. M. , Gurbanov A. G.
Published: December 2022

The paper presents the results of the U-Th-Pb isotope system study of the accessory zircon from the basalts of the Ghoithsk volcanic region (GVO) of the Western Caucasus. The sample for isotope dating was taken from basalt porphyrites of the Chataltapa volcanic complex, in the Tuapse River basin. It was shown by using of the ion microprobe isotope dating method of the zircon, that the effusion of basalts of the Chataltapa volcanic complex of the GVO occurred in the Jurassic at the boundary of the Aalenian and Bajocian age (169 Ma), during the tectonic transformation of the Greater Caucasus riftogenic basin. A low Th/U ratio was obtained for zircons from basalts, which is more typical for rocks of acidic composition. This fact indirectly confirms that the evolution of the Jurassic rift magmatism in the Caucasus occurred due to the assimilation of the continental type crust.
Bound water of the rock samples of the Bazhenov formation before and after extraction
Authors: Rodkina I. A. , Kazak E. A.
Published: December 2022

The first results of determination of the content of different types of bound water by hygrometric method — adsorption isotherm method — for extracted rock samples of Bazhenov formation are presented. All obtained water sorption isotherms have a well-defined S-shape, which allows to determine the maximum possible amount of bound water of different types (mono -, poly-and capillary condensation) in all studied samples. The inflection points of the isotherms of the extracted samples fully correspond to the inflection points of the isotherms of the native samples. Based on the obtained results, it is possible to further estimate the specific surface area of the samples, and then determine the hydrophobicity coefficient and the parameters of the associated oil saturation.

Authors: Kayukova E. P. , Filimonova E. A.
Published: December 2022

The quality of fresh groundwater in the foothills of the Crimea, including that used for the water supply of the Crimean base of St. Petersburg State University and the Crimean educational and scientific center of Lomonosov Moscow State University, is considered. The results of longterm monitoring of the chemical composition of fresh water used for drinking purposes are presented and priority pollutants are identified. Hydrochemical modeling was carried out to calculate transport forms of chemical elements and subsequent assessment of their toxicity. The study area is located in the area of active water exchange, so in the groundwater most of the chemical elements are contained in concentrations below the level of biologically significant.
Ion Exchange Capacity of the Bazhenov Formation Shales from the Central and Southern Parts of the Nizhnevartovsk Arch of Western Siberia
Authors: Kazak E. S. , Kazak A. V. , Rodkina I. A. , Kharitonova N. A.
Published: December 2022

The paper provides experimental characterization of the ion-exchange capacity of low-permeable shale rocks of the Bazhenov Formation of the central and southern parts of the Nizhnevartovsk arch, Western Siberia. We found that the cation exchange capacity (3.30–17.01 meq/100g) and the speciﬁc surface area (10.05–12.66 m2/g) depend on the clay minerals content, but not on the kerogen. The paper describes type of the exchange complex of the studied Bazhenov Formation rock samples and discusses the possible reasons for the distribution of exchangeable cations. The cation exchange complex of most part of studied Bazhenov Formation samples has a marine type (rCa/(rNa+rK)<1).

Authors: Bryantseva G. V. , Sim L. A.
Published: December 2022

Based on the comparison of relief and geological data, the newest structural elements were identiﬁed, actively developing in the form of systems of uplifts and depressions, deciphered from satellite images and topographic maps in the form of lineaments predetermined by discontinuous disturbances. As a result of the research, neotectonic shear stress ﬁelds have been restored with orientations of the submeridional compression axes of tectonic stresses of the I rank, which is generally in agreement with the subhorizontal compression axes, mainly oriented submeridionally, established in almost all regions of Northern Eurasia.

Published: December 2022

In the Moscow region, Eopleistocene deformations (1,8 million years) were studied for the ﬁrst time. The activity of modern geological processes is associated with them. The qualitative and quantitative characteristics of deformations were carried out on the basis of the structural-geodynamic method and morphometric analysis of a large array of GIS data. The stage-by-stage amplitudes and velocities of neotectonic uplifts have been estimated. And the gradient of the strain rate of the Moskvoretskaya zone was calculated.

Authors: Krylov I. O. , Nikulin I. I. , Samsonov A. A. , Korshunov D. M. , Vildanov D. I.
Published: December 2022

The plagioclases of the Kharaelakh intrusion on the western part of the Oktyabrsky deposit were analyzed by infrared spectroscopy. Analysis of 130 Fourier-IR absorption spectra of plagioclases with selective veriﬁcation of their chemical composition by X-ray spectral microanalysis indicates a regular change in the isomorphic series from albite (1150, 1096 cm–1) to anorthite (1142, 1275 cm–1), depending on the degree of diﬀerentiation of rocks in the intrusion. According to Fourier-IR spectroscopy, albite is conﬁned to olivine-containing and olivine gabbro-dolerites. Anorthite is evenly distributed in gabbro-dolerites, but predominates in leucocratic gabbro. Among the impurity elements in the structure of the mineral, Fe3+ is noted at peaks of 1580–1644 cm–1 in picrite gabbro-dolerites, where ore interspersed mineralization of chalcopyrite, pyrrhotite, and pentlandite is directly developed. In addition to iron impurities, aluminum, potassium, barium, and strontium are also characteristic impurities in plagioclases. The totality of the data used in the section of the intrusion increases the indicative value of plagioclases and can be recommended as an additional mineral criterion of ore content.

Authors: Agibalov A. O. , Zaitsev V. A. , Manuilova E. A. , Sentsov A. A.
Published: December 2022

Using the method of cluster analysis of morphometric parameters of the relief, the areas within which most of the epicenters of modern earthquakes of the Voronezh anteclise are located are identiﬁed. With the help of computer modeling, the areas of possible formation of new small-length discontinuities in the modern stress ﬁeld are outlined. On the basis of complex geological and geomorphological data we created a tectonophysical model that explains the nature of seismicity by the development of geodynamically active zones in a shear environment with the orientation of the axis of maximum compression in the north-west direction.

Authors: Nurislamov A. I. , Rastorguev A. V.
Published: December 2022

An improved algorithm for modeling the dynamics of petroleum product lenses based on the planned ﬁltration equations is presented. The program code «Oilfem 2», which implements the algorithm, is supplemented with a generator of non-orthogonal grids, the ability to create groundwater models or import them, the dependence between the pumping rate of the lens of petroleum products and its thickness is taken into account. The improved program code was applied on a test task to eliminate oil pollution, which is a round lens of petroleum products. The results of this work showed a good correspondence between the two solutions according to two criteria: the change in the ﬂow rate of pumping oil products and the change in the volume of free oil products over time.

Authors: Lyamina L. A. , Kharitonova N. A. , Rastorguev A. V. , Chelnokov G. A. , Bragin I. V.
Published: December 2022

The study of the inﬂuence of hydrodynamic factors on the occurrence of nitrogen thermal waters in crystalline massifs, by the example of the Kuldur ﬁeld, is presented in the article. The results of two-dimensional modeling (based on FEFLOW code) of several variants of formation and circulation of therms in the study area are considered. Model parameters included temperature (130–140 °C), calculated on the basis of geothermometers, and the residence time of waters in the rock massif (68 800–254 000 years), estimated by means of 14C and 4He dating. The modeling results show that exactly the ﬁltration parameters of the granite massif are the main factor controlling the dynamics of ﬂuid movement and, consequently, the relative age of thermal waters. It is also found that the ﬁltration characteristics of the fault zone have a signiﬁcant inﬂuence on the temperature of thermal water discharge.

Published: December 2022

The issues of improving the eﬃciency of processing the results of studies of the ﬁltration properties of reservoirs within the oil and gas producing areas of the central part of the West Siberian oil and gas province are considered. The high degree of development of the hydrocarbon resources of the studied territory is characterized by the presence of long-term developed deposits, which determines the solution of tasks aimed at increasing the success of the search for complex deep-lying reservoirs, the eﬃciency of their exploration and additional exploration, since the overlying productive horizons are practically developed. This task is one of the most important at the current stage of ﬁeld development in this region, in the context of falling oil production at the main large ﬁelds, and has no unambiguous solution.

This article covers the issues of reservoir modeling using new scientiﬁc and methodological approaches to the processing of geophysical data and the possibility of using modern software products when grouping development objects according to criteria corresponding to a reservoir of a certain lithotype. This approach allowed us to build high-quality geological models and justify the use of the most eﬀective complex of geophysical studies for modeling low-amplitude (no more than 15 m) and small-sized (less than 20 km2) oil deposits. In the course of research: The results of the reservoir ﬁltration properties were processed; low-amplitude and small-size sediments of channel sediments (river valleys) were established; the industrial oil and gas content of complex sediments characterized by low-amplitude and small-size sediments (Tyumen formation, object Ю2) was proved; The interpretation of geophysical studies of wells was carried out, the results were compared with the energy characteristics of the reﬂected waves (seismic studies), zones saturated with water-oil-gas ﬂuid were established (3D models were built), and the possibility of using this technique for identifying and mapping complex deep oil deposits was shown.

Authors: Yang H. , Soboleva E. V.
Published: December 2022

This article presents the results of geological and geochemical studies of the organic matter of source rocks and oil from reservoirs in the Karamay Formation (Anizian–Ladinian stages) in the eastern part of the Fukang Depression in Junggar petroleum basin. The quantity, quality, and degree of maturity of the organic matter in clayey mudstones in upper part of the Karamay Formation (T2k) were considered and the composition of the original organic matter, the conditions of its accumulation and the degree of maturity were reconstructed using pyrolytic parameters and biomarkers. The dark gray and gray mudstone in upper part of the Karamay Formation accumulated in fresh or low salinity lakes with relatively reducing conditions. At present, the organic matter of the Formation within the depression is in the zone of mesocatagenesis MK1–MK3, and therefore has not fully realized its oil-geological potential. It has been previously established that mudstones in upper part of the Karamay Formation provided the hydrocarbon fl uids for the Karamay reservoirs located in the submerged part of the Fukang Depression.

Published: December 2022

For the Dzhimidonsky vein polymetallic deposit (North Ossetia, Russia), formed in the Middle Jurassic time, it was established by the nature of the distribution of rare-earth elements in the veins and rocks that the sources of REE and ore components were a combination of host rocks of different composition (PR3–PZ1, PZ3) and were replaced in time. Geochemical data served as the basis for the development of new methods of equilibrium-dynamic modeling and assessment of the influence of the change in time and space of fluid flows from different sources on the processes of ore formation.

Norilsk ore field: the new metamorphic-hydrothermal mineral association — pure zvyagintsevite and silver, hibbingite, Mn-hibbingite, siderite, sphalerite and phosgenite in the magmatogenic putoranite ores
Authors: Spiridonov E. M. , Ivanova Yu. A. , Naumov D. I. , Korotaeva N. N. , Serova A. A.
Published: December 2022

The unique magmatogenic putoranite ores are developed within deep horizons (>1750 m) of the northeastern flank of the October deposit in the Norilsk ore field. Th ese are coarse-grained putoranite aggregates with lamellaes of moihoekite and isolated pentlfndite disproportionation. The composition of putoranite is: [(Fe17.6–17.9Ni0.4–1.1Co0–0.1)18–19Cu15.8–17.0]35S32; the composition of moihoekite is: [(Fe17.8–18.0Ni0.2–0.3Co0–0.1)18.2– 18.3Cu17.7–17.8]36S32; pentlandite contains 1,75  wt% of Co, its composition is: (Ni4.41Fe4.36Co0.23)9S8. Ores hold pneumatolytic stannopalladinite Pd5CuSn2, polyarite Pd(Bi,Pb), plumbopolyarite Pd(Pb,Bi), tetraferroplatinum Pt2Fe(Fe,Cu,Ni), tulameenite Pt2Fe(Cu,Fe,Ni) and kustelite (Ag,Au). Bornite is widespread in tectonized ores, as well as late hibbingite and Mn hibbingite (Fe2+,Mn2+)2(OH)3Cl, siderite and Mn siderite (Fe2+,Mn2+)[CO3] aggregates, replaced magnetite and Cu-Fe-Ni sulphides. Pure zvyagintsevite Pd3Pb and native silver compose syngenetic inclusions in hibbingite and siderite aggregates. Similar zvyagintsevite replaces pneumatolytic polyarite and plumbopolyarite. Metamorphogenic-hydrothermal zvyagintsevite probably arose from their material. Th is zvyagintsevite is sharply diff erent from pneumatolytic zvyagintsevite by the absence of Pt, Sn, Bi, Sb and Hg in its composition. The first detected hypogenic phosgenite Pb2[Cl2/CO3] forms pseudomorphoses aft er galena, sometimes with hibbingite. Th e described low-temperature metamorphogenic-hydrothermal mineral association arose involving carbon dioxidechloride solutions in reducing conditions. Later metamorphogenic-hydrothermal hisingerite, bornite and barite, partially replacing hibbingite, siderite and Cu-Fe-Ni sulfides, arose with an increased fugacity O2.
Late glacial glaciomarine and Holocene marine sediments in the eastern part of the Barents Sea: structure composition; thickness; conditions of formation
Authors: Epstein O. G. , Dlugach A. G. , Starovoytov A. V.
Published: December 2022

Geological-geophysical dates are showing that Holocene marine and Late Glacial glaciomarine sediments in the eastern Barents Sea represent seismostratigraphic complexes (SSC), accordingly SSCI and SSCII. Th e composed of glacial mineral matter sediments SSCII formed in the time of the Barents Sea shelf deglaciation, but the sediments SSCI deposited in conditions of open marine basin and are terrigenious. Features of the structure, composition and thicknesses of sediments SSCII are defi nite by melting conditions of degraded glacier masses and by character of originated sedimentation basins, but of sediments SSCI — by hydrodynamic factor and, partially, — by processes of last glacial eustatic marine transgression.
Cretaceous volcanism and intrusive magmatism features in the Mendeleev Rise region (Arctic Ocean) according to seismic data
Authors: Rodina E. A. , Nikishin A. M. , Startseva K. F. , Posamentier H. W.
Published: December 2022

The current paper is based primarily on the interpretation of 2D seismic lines for the Amerasian Basin. A synrift complex has been identified in half-grabens almost everywhere within the Alpha-Mendeleev Rise and conjugate basins according to the results of seismic data interpretation. Various magmatism features within the synrift complex have been identified on seismic profiles: plateau basalts; sills and dikes; reflections similar to SDRs (Seaward Dipping Reflectors Sequences) and volcanoes. Regional extension and synchronous widespread magmatism are probably associated with the formation of the High Artic Large Igneous Province (HALIP) in the Aptian-Albian. Considering the data on the isotope ages of igneous rocks for the Mendeleev Rise, it is assumed that the top of the synrift complex has an approximate age of 100 Ma and the bottom has an approximate age of 125 Ma. The Alpha-Mendeleev Rise was formed simultaneously with conjugate basins in the Aptian-Albian. An axial line can be drawn along the Alpha-Mendeleev Rise. To the west of the axial line, reflections similar to SDRs dip towards the Podvodnikov basin. To the east of the axial line, reflections dip towards the Toll, Mendeleev, Nautilus and Stefansson basins. The reflections converge in the central parts of the basins. The Alpha Mendeleev Rise is a double-sided volcanic passive continental margin. The Podvodnikov, Toll, Mendeleev, Nautilus, and Stefansson basins are rift basins with thinned continental crust at the base. Their development was interrupted before the start of spreading and the oceanic crust formation.

clinoform complexes in the new sedimentary basins without drilling. Based on complex analysis of the seismic, well logs, well tests and core data in the northern Priobskoye field, the correlation between clinoform geometry, edge trajectory and distribution pattern of the reservoirs in the productive formation AS is established. The highest flow rates and reservoir properties are typical for bar deposits, proximal fan and slope channels. Deposits of bars are formed at the high stand system tract and at the beginning of the falling system tract on the edges of tangential clinoforms with gently ascending, flat and descending edge trajectory. Deposits of basin floor fans and slope channels are confined to the drop in the relative sea level and its low stand; it is advisable to search for them at the bottomset of tangential clinoforms with a descending edge trajectory and in gently cross-bedded clinoforms.

Published: December 2022

The results of a comprehensive study of the boundaries of the Turonian-Coniacian in the Upper Cretaceous deposits of the Abinsky region of the North-Western Caucasus, composed of rhythmically constructed carbonate strata of the hemipelagic type, are presented. Biostratigraphic analysis of foraminifera complexes made it possible to identify zones in the section that are comparable to those proposed for the Point of the Global Stratotype of the boundary of the Coniacian in Germany. On the basis of chemostratigraphic (isotopic) studies, the levels of abiotic events traced in the section and other territories have been established. The Shapsug section, after further study, can be proposed as a possible Hypostratotype (Limitotype) of the Turon-Coniacian boundary for the territory of the Russian Federation.
Typification of gold deposits for evaluation and exploration purposes
Authors: Kushnarev P. I. , Samsonov A. A.
Published: December 2022

The issues of choosing the parameters of the exploration network based on quantitative criteria of exploration: the accuracy of the assessment of average grades and the error of geometrization are considered. Acceptable values of criteria for C1 category reserves are established based on the results of the analysis of actual data. The typification of gold deposits is based on an assessment of the scale of deposits, their morphology and fractal dimension; an assessment of the variability of gold grade in samples or composites is also used. To assess geometrization errors at the early stages of geological exploration, a method for determining them based on the positions of fractal geometry and on the results of geostatistical studies is proposed.
Assessment of oil-and-gas-bearing capacity of pre-jurassic and jurassic deposits of the central part of the West Siberian plate
Authors: Schuster V. I. , Tyukavkina O. V. , Shelepov V. V. , Kapitonova I. L.
Published: December 2022

There were examined the issues of studying the features of the lithological and petrographic composition and the formation of oil deposits within the fields of the Surgut dome fold and the Frolov megadepression. It was noted that the formation of deposits of the sedimentary cover is associated with the peculiarities of the geological structure and the oil-bearing capacity of the basement rocks. In the considered territory, a high level of oil-bearing sedimentary cover is observed within the central part of the Surgut dome fold, and the deposits of the Pre-Jurassic part of the section can be additional sources of intensification of hydrocarbons in the Lower-Middle Jurassic deposits. The presence of zones of deep snaps is a search criterion for the detection of secondary reservoirs in them both — in destruction zones, basement, and in the Lower-Middle Jurassic deposits, therefore, deposits can be formed due to the vertically ascending migration of deep fluids through faults that cross the basement and horizons of the sedimentary cover.

There were examined the issues of the prospects for the oil and gas content of the Lower-Middle Jurassic deposits, which must be associated with both granitoid massifs and the details of identifying the conditions of sedimentation and the establishment of contact zones of the sedimentary cover with the underlying formations.

The aim of this work is to determine the provenance for the Upper Visean Solnechnay formation (The Southern Urals) using the U-Pb dating of detrital zircons. 138 zircon grains with discordance range of ± 10% were selected for the analysis. The vast majority of the zircons yielded the Ordovician and Cambrian ages. The main peak corresponds to the beginning of the Ordovician period (circa 480 Ma), and the secondary peaks correspond to the beginning of the Late Ordovician, the middle Cambrian, and the early Cambrian. The clastic material was derived from the East Ural megazone exclusively.

Published: December 2022

This article presents the results of a comprehensive study of the Maastrichtian sequence of the Kyz-Kermen Mountain, located on the territory of the South-Western Crimea. The section is represented by a rhythmically bedded carbonate sequence, which is gradually replaced by carbonate sandstones.The study of rocks in thin sections made it possible to identify eight lithotypes, and chemical analyzes showed changes in the content of individual elements in the rock composition. Interpretation of data about planktonic and benthic foraminifers made it possible to determine the age of the deposits, define to zones and beds with fauna as well as to establish another supposed hiatus in the middle of this section, coinciding with a noticeable change in the composition of the rocks.Quantitative analysis of the association of foraminifers together with lithological and geochemical results made it possible to establish that the studied section was formed an open carbonate platform at depth of the middle–outer shelf.

The article considers the results of a comprehensive study of the Cretaceous-Eocene deposits of the Central Crimea (Ak-Kaya mount.). The temperature and salinity of the formation of Maastrichtian and Eocene rocks have been determined, and a correlation has been made with the global climatic event EЕСO (Early Eocene Climate Optimum). The synchronicity of the formation of steep submeridional fractures and the basal horizon of the Eocene has been proved. Three major stages of deformation have been identified: pre-Eocene, Eocene, and post-Eocene. It is shown that the Eocene stage corresponds to the formation of paleoseismic dislocations during the main phase of tectonic activity in the Pontids (Eastern Turkey).
Geological features, hydrothermal alterations, and cryptic mineralogical zonation of the Kyzyk-Chadr porphyry copper deposit (Tyva Republic)
Authors: Starostin I. A. , Girfanov M. M. , Yartsev E. I.
Published: December 2022

The altered rocks of the Kyzyk-Cha dr deposit are predominantly composed of quartz and potassic dioctahedral micas of the phengite–muscovite series, that dominate in almost all zones of the alteration halo. Parageneses of albite with chlorite and epidote are only characteristic of peripheral sections of the halo, subjected to the propylite-type alteration. Quartz-potassium feldspar alterations are distributed in the central and deep-seated sections of the halo. Petrographic investigations of hydrothermal alterations and results of the X-ray structural analysis and infrared (IR) spectroscopy of micas from the mineralized quartz-sericite metasomatites were applied to reveal a cryptic mineralogical zonation of the Kyzyk-Chadr porphyry copper deposit. Elements of the cryptic mineralogical zonation, revealed based on results of the X-ray study and IR spectroscopy of light-colored micaceous metasomatites of the deposit, are caused by variable proportions of the phengite and muscovite components in their composition. The phengite component predominates in the central and deep-seated sections of the alteration-mineralization halo of the deposit, while the muscovite component progressively increases toward its flanks and upper sections. This tendency correlates with the general vector of the mineralogical alteration-mineralization zonation and are supposedly explained by changing PT conditions within the porphyry copper ore-magmatic system. The indicator of the cryptic mineralogical zonation by the “phengite-muscovite” relationship can be applied for prospecting and preliminary evaluation of porphyry copper type deposits, being used as an objective guide for correlation of already obtained ore-grade interceptions and forecasting the ore bodies.

Published: December 2022

The modern structure of the Zagros folding-thrust structure was formed under the influence of collision processes on the eastern flank of the collision zone of Eurasia and Arabia. Based on structural-geomorphological analysis and spatio-temporal features of the seismicity distribution, the article considers the features of the latest and modern geodynamic development of Zagros as a classical collision orogen. It is noted that the orogen is at the stage of erosion development, its seismic activation is associated to a greater extent with local deformations within individual blocks and is transformed under the influence of intense man-made impacts associated with the extraction of hydrocarbons within the Mesopotamian Lowland and the Persian Gulf.

Ayrıca görüşmecilerin sosyal iletişim ağını genişletmek, kimlik kazanmak ve maddi ve manevi menfaat temin etmek gibi amaçlarla kadın kollarına üye oldukları, hayır işleri, hasta ziyareti, kermes gibi kfaaliyetlerde görev aldıkları anlaşılmıştır
Agreement and argument realization in Mian discourse
Authors: Fedden Sebastian
Published: December 2022

A common assumption about the function of gender agreement in discourse is that it serves referent identification and reference tracking. There is some evidence in favour of this view, and an increasing body of research which finds no foundation for it; this study further supports the latter perspective. It is based on a fully annotated corpus of the Papuan language Mian and uses a noteworthy property of the Mian agreement system: object agreement in transitive verbs is “sporadic”, i.e. it depends on the lexical type of a transitive verb whether it agrees with its object. Therefore we can measure whether speakers of Mian manipulate overt vs. null arguments in discourse to compensate whenever lack of agreement might make argument reference ambiguous. The results clearly show that the proportions of overtly realized objects for agreeing verbs and non-agreeing verbs do not differ significantly, thus lending little support to the claim that gender agreement serves a major function in reference tracking in discourse.
Microvariation in agreement inflection: Subject clitics vs inflection
Authors: Pescarini Diego
Published: December 2022

This article examines the relationship between the presence and shape of subject clitics and verbal endings in a sample of 187 Italo-Romance dialects. It is found that in the majority of languages subject clitics outnumber distinctive inflectional endings. The absence of underspecified systems militates in favour of diachronic and synchronic explanations claiming that the presence of subject clitics is related to the richness of inflection. At the same time, however, the predominance of overspecified systems indicates that further factors are at play in shaping inventories of subject clitics. The second result is that, from a geolinguistic perspective, close dialects exhibit more similarities in the inflectional system than in clitic systems. This brings further support to the claim that inventories of subject clitics do not reflect the array of inflectional endings, whereas some further factors are probably involved in the emergence of subject clitics. Such factors might be either feature geometries/filters, as proposed in the previous literature, or third factors in Chomsky’s sense, i.e. factors that are related to computational efficiency and/or processing costs.
