Significance of Panned Heavy Concentrate Sampling in Geochemical Prospecting for Gold: A Study from Atkur Area, Gadwal Schist Belt, Andhra Pradesh
Authors: Ananda Murthy S. , Aneel Kumar V. , Krishna Rao P. V. , Mallick Sekhar 
Published: November 2024

Abstract
Heavy-concentrate has been found to be the most suitable sampling medium in geochemical exploration for gold in Atkur area of Gadwal schist belt, Mahabubnagar district, Andhra Pradesh. Au-contents in panned heavy concentrates of soil samples from B-horizon and termite mounds helped in improving gold anomaly contrast. SEM and heavy-concentrate analyses of termite samples reaffirm their utility in exploration for gold. Hence, the study of heavy fraction of soil and termite mound can be used as an important tool to reveal the subtle anomaly present in the conventional samples.
Geochemistry of Groundwater Over Sukinda Ultrabasic - Basic Rocks, Jajpur District, Orissa
Authors: Som S. K. , Joshi R. , Neogi G. , Mukherjee M. M. 
Published: November 2024

Abstract
The geochemistry of groundwater over Sukinda ultrabasic - basic rocks, Orissa, covering an areat extent of about 50 km2, has been investigated to understand the hydrogeology of the area. The dominant geochemical processes were interpreted from geochemical data and mass balance calculations. The entire study area contains two broad lithounits comprising ultrabasic rock at the centre and metabasics at eastern and western flanks, with a general groundwater flow pattern from east to west. The groundwater in the area is fresh, meteoric in origin with high Na, Kover metabasics as well as the northern part of the ultrabasic rock, and high Mg, HCO3- and TDS over the remaining ultrabasic rock. Mineral solubility study of Mg- phases present in the system shows that the present day geochemical conditions are not suitable for Mg2+ precipitation and most likely, serpentine is the dominant Mg2+ contributer in the system. Mass balance calculations based on mixing ratio along the E-W flow path show that K and to some extent Na behave conservatively in the evolution of groundwater. The conservative mixing model presented here evaluates the formation of secondary mineral phases along the flow path.
Geochemistry of Sphene from Granodiorites Surrounding the Hutti-Maski Schist Belt: Significance to Rare Earth Element (REE) Modeling
Authors: Basir S. R. , Balakrishnan S. 
Published: November 2024

Abstract
A study of the distribution of REE in sphene from three granodiorite samples around NNW-SSE trending Hutti-Maski schist belt has been described here. Two distinct sets of sphene-melt Kd, values for REE have been observed among the three sphene-whole rock pairs studied. The chondrite normalized REE pattern of sphene from east (Gajalagatta) and northeast (Uti) granodiorites show LREE enriched and HREE depleted patterns with slight or no negative Eu anomaly. These REE patterns are parallel to the respective whole rock samples. But the chondrite normalized REE pattern of sphene from the sample to west of the schist belt (Ankasdoddi) has markedly depleted Ce and Nd with slight or no negative Eu anomaly and steeply fractionated HREE, resulting in a convex-up pattern. The variation of REE Kd, values of sphenes is not due to differences in the composition of host magmas (because they are all granodiorites with identical major element abundances), but could be a function of temperature of crystallization. Small degrees of fractional crystallization of sphene from granodiorite magmas would result in residual magmas having lower REE abundances either with parallel REE patterns or HREE depleted fan shaped REE patterns, depending on the Kdvalues.
Partial melting of granitoid rocks, leaving minor amounts of sphene in the residue gives rise to melts with lower REE abundances than the source. The REE patterns of the melts are parallel to the source if one set of REE Kd sphene-melt values are considered. If the other set of Kd, values are used, the partial melts have (fan shaped) REE patterns with more depletion for heavy REEs.
Evidence of Epithermal Activity and Gold Mineralization in Newania Carbonatite, Udaipur District, Rajasthan
Authors: Golani P. R. , Pandit M. K. 
Published: November 2024

Abstract
The geological, geochemical and C- and Pb-isotopic evidence available on the Newania Carbonatitic Body (NCB) in southern Rajasthan are not entirely incontrovertible from the point of view of carbonatite magmatism. Based on recognition of calcite-lined vugs, 'dog-tooth spar' and 'jig-saw puzzle' structure, the hematite bearing ankeritic carbonates (the ankeritic 'carbonatite') are considered as epithermal emplacements into dolomitic (magnesio-) carbonatite. Seven samples collected from hematite bearing ankeritic (±sideritic) carbonates, which constitute an important component of the NCB, have given gold values ranging between 0.93 to 1.36 ppm. The significance of this find lies in the association of gold with oxides and carbonates of hydrothermal affinity.
Petrology of Basic Granulites from Maruturu Near Anakapalle in the Eastern Ghats Granulite Belt
Authors: Rao A. T. , Srinivasa Rao K. , Srinivas S. 
Published: November 2024

Abstract
Basic granulites frequently occur in garnetiferous quartzo-feldspathic gneisses and rarely in garnetiferous sillimanite gneisses, calc-silicate rocks and quartzites in the entire Eastern Ghats Granulite Belt (EGGB). Commonly these basic layers are parallel to the foliation and are occasionally boudinaged. These share a common tectonic and metamorphic history with those of the associated litho-units. There are also unusual basic granulite dykes which crosscut the foliation in quartzo-feldspathic gneisses, folded calc-silicate rocks and basic granulites at Maruturu near Anakapalle in the EGGB. The two generations of basic granulites are even grained with a polygonal annealed mosaic and characterised by the mineral assemblage: coexisting pyroxenes and plagioclase. The mineral composition data of coexisting pyroxenes indicate large scale equilibrium at granulite facies conditions. Both types of basic granulites have almost similar bulk composition and have tholeiitic affinity. The basic granulite dykes have low contents of REE with a smooth distribution pattern and a general decrease from LREE to HREE. The revival of basic magmatism during post D1 and D2 at Maruturu reveals that extensional set-up recurs in the EGGB. The basic granulites of Maruturu are correlated with Proterozoic metabasic dykes in East Antarctica and Western Australia. The 1300 Ma basic granulites reported in Maruturu and Rayagada in the vicinity of Maruturu indicate that these intrusive basic bodies are coeval with the dyking events in Eastern Albany Mobile Belt in Western Australia and Vestfold Hill Block in Prydz Bay region in East Anatarctica.

Geochemical Discrimination Diagrams: A Simple Way of Replacing Eye-Fitted Field Boundaries With, Probability Based Classifier Surfaces
Authors: Agrawal Salil 
Published: November 2024

Abstract
The subjective, eye-fitted, field boundaries in geochemical discrimination diagrams constitute one of the possible reasons for their often-noted inability to determine the source regime/tectonic environments of igneous rocks. A simple method is described here to replace the eye-fitted field boundaries between the groups with the probability based classifier surfaces. It involves projection of the assignment rules obtained from linear discriminant analysis onto the binary or ternary discrimination diagram of raw variables. The method is illustrated by obtaining classifier surface between I- and S-type granites in Na2O-K2O space and between Anorthosite/Rapakivi (AR) and Ring Complex (RC) granites in Na2O-MgO space. The need for explicitly ensuring adequacy of samples, selection of suitable variables, evaluation of rate of misclassification and a better understanding of the unique influence of tectonic environments on magmatic process is emphasized for optimizing the performance of the classifier surface.
Late Archaean-Early Proterozoic Rb-Sr Isochron Age of Granite from Kawadgaon, Bastar District, Madhya Pradesh
Authors: Singh Yamuna , Chabria T. 
Published: November 2024

Abstract
Whole-rock Rb-Sr analysis of ten granite samples from Kawadgaon, Bastar craton, yield an isochron corresponding to an age of 2497±152 Ma (2s) and initial 87Sr/86Sr ratio of 0.7142±0100(2s). The data suggest emplacement of Kawadgaon granite during the ca. 2500 Ma Archaean-Proterozoic transitional event in the craton.
Late Archaean Granitoid With a Ring Structure Around Chandra, Mandya District, Karnataka
Authors: Krishnamurthy P. , Sarbajna Chanchal 
Published: November 2024

Abstract
A ring-like structure is defined by a late Archaean granite around Chandra. It is a fertile granite with a parental status akin to the rare metal pegmatite-hosted deposits of Li-Be-Nb and Ta around Allapatna-Marlagalla. This observation has important implications for new exploration targets for rare metal pegmatites in southern Karnataka and also geological evolution of the terrain as a whole.
Interpretation of Gravity Field Over the Perinthatta Anorthosite, Northern Kerala
Authors: John Kurian P. , Radha Krishna M. , Nambiar C. G. , Murthy B. V. S. 
Published: November 2024

Abstract
Gravity surveys have been carried out over the Perinthatta anorthosite and the adjoining areas and the results are discussed. The Bouguer anomaly map reveals the absence of any conspicuous gravity anomaly corresponding to the pluton and thus precludes the existence of larger mafic portions of the pluton in the immediate subsurface region. The residual gravity map obtained by regional-residual separation method shows a minor positive gravity field of irregular shape with localised highs of 6 - 12 mgal within and around the anorthosite body. TWo-dimensional gravity interpretation of profiles across the pluton suggests subjacent nature and lensoid shape for the anorthosite which is underlain by small isolated cylindrical bodies (? 2.5 km diameter) of higher density (2.9 gm/cc) extending 3 - 7 km downwards. These cylindrical bodies are inferred as either the mafic/oxide rich portions of the pluton sagged down during crystallization or the individual feeders of the plagioclase-rich mushes, which coalesced in the upper crust to give rise to the massif.

Authors: Sengupta Siddhartha , Chakraborty Abhijit , Bhattacharya H. N. 
Published: November 2024

Abstract
External casts comparable with Polyplacophora (Mollusca), collected from the sand/silt-mud alternation facies (turbidite) of upper Talchir sediments of Dudhi Nala, West Bokaro basin, Hazaribagh district, Bihar are described and illustrated here for the first time. These sediments were reported to be unfossiliferous. Polyplacophoran morphology of the fossils indicate a marine link of the West Bokaro basin during the upper Talchir times. Dudhi Nala area is presently considered to be yet another locality proximal to the eastern limit of the Lower Permian marine incursion in the Indian peninsula along the Raniganj-Daltonganj-Manendragarh-Umaria belt.
Significance of the Archaean Bimodal Volcanics from the Ramagiri-Schist Belt in the Formation of Eastern Dharwar Craton
Authors: Mishra Meenal , Rajamani V. 
Published: November 2024

Abstract
The central arm of the trident shaped Ramagiri schist belt includes a central block which consists predominantly of bimodal (mafic-felsic) volcanics, apart from minor metasedimentary units. The geological set up of the various rock types suggests that the central block could be a tectonic melange. The metatholeiites and the felsic volcanics of the central block show similar LREE - enriched and fractionated REE patterns; the metatholeiites however. show a much larger variation in abundances. It has been suggested that the protoliths to the Ramagiri central mafic suite of bimodal volcanics were formed by different extents of melting of the metasomatically enriched mantle sources and were emplaced in an island arc setting. We suggest here that partial melting of similar metatholeiites, constituting an arc crust, at - 8 kbar pressures and at -1000 °C temperatures, produced magmas to the associated felsic volcanics. The geochemical characteristics of the mafic and felsic volcanic rocks in the Ramagiri belt, as well as the adjoining Sandur belt, have many similarities to those of the modern day island arc volcanic suites. The idea that the Phanerozoic style magmatic and accretionary tectonic processes operated during the Late Archaean suggested from the studies of granitic rocks in the Eastern Dharwar craton is corroborated by the metavolcanics of the Ramagiri schist belt.
Geoenvironmental Appraisal of Haryana
Authors: Thussu J. L. 
Published: November 2024

Abstract
Haryana primarily an agricultural State is rapidly transforming into an industrial State. Most part of the area in the State is occupied by vast stretches of Quaternary Alluvial plains separating the rocks of Delhi Supergroup in the south and west and Siwalik in the northeast. Various geomorphic landforms have been identified. Central Alluvial Plains occupy about ninety five percent of the total area of the State while the hard rocks are exposed only in five percent of the total area. Based on geological, geomorphological set up and geochemical studies, it has been possible to conclude that the potential environmental hazards distinctly differ in each land form. Two types of environmental hazards, viz., natural hazards and biotic or anthropogenic hazards have been recognised. The natural hazards, viz., salinity, salt efflorescence, sand remobilisation, bad land and water logging mainly affect the Central Alluvial Plains, while biotic or anthropogenic hazards, viz., mining, quarrying, wastage disposal, leakage from canals and excess drawal of water affect all the geomorphic landforms. Effective management controls have been suggested to mitigate the natural hazards and proper planning measures to control biotic hazards.
Microtextures on Quartz Grains of Campanian-Maastrichtian Sediments of Ariyalur Group of Tiruchirapalli Cretaceous, Tamil Nadu - Implication on Depositional Environments
Authors: Madhavaraju J. , Ramasamy S. 
Published: November 2024

Abstract
Studies on the quartz grains of the Campanian-Maastrichtian sediments of the Ariyalur Group of Tiruchirapalli Cretaceous, Tamil Nadu, using Scanning Electron Microscope (SEM) have brought out nineteen distinct microtextures. They have been grouped into features based on their mode of origin. Of these, thirteen are of mechanical and five mechanical and/or chemical origin while one distinctly chemical. The quartz grains of the Ariyalur Group sediments show a wide range of conchoidal fractures, straight steps and arcuate steps formed during the liberation from the metamorphic and igneous source rocks. The microtextures - v's, pits, straight and curved scratches are characteristic of the marine environment. The frequency of these features is higher in the grains from the Sillakkudi, Kallankurichchi and Ottakkovil Formations. Rarity of these features on quartz grains from the Kallamedu Formation is suggestive of variation in transport and depositional conditions. It has been inferred from the microtextures that the source for the quartz grains in the Ariyalur Group sediments has been the nearby Precambrian crystalline basement.
‘AWAKENING’ FOSSILS IN CHINA: INTERNATIONAL EFFORTS IN PUBLISHING PALAEONTOLOGIA SINICA
Authors: SUN CHENGSHENG 
Published: November 2024

ABSTRACT
The Palaeontologia Sinica founded in China in 1922, was one of the most important Chinese academic journals with international influence in the first half of the 20th century. It originated from Ding Wenjiang’s (V. K. Ting, 1887–1936) emphasis on paleontological research in China. The success of its publication was also due to the strong support of Swedish geologist Johan G. Andersson (1874–1960) and the academic guidance of American paleontologist Amadeus W. Grabau (1870–1946). Mainly based on fossil collections in most parts of China at the time, 126 monographs of the journal were contributed by 50 authors from different countries, and various fossils lying dormant in the land of China were brought to light.
A HISTORY OF 20TH CENTURY GRAPTOLITE STUDIES IN MALAYSIA: THE ROLE OF CLIVE RODERICK JONES
Authors: SAPARIN MUHAMMAD AQQID , ISMAIL MOHD SUHAILI 
Published: November 2024

ABSTRACT
The stratigraphy of Peninsular Malaysia (formerly Malaya) was first described by Scrivenor (1931) in ‘Geology of Malaya’, which at that time recognized no strata older than Carboniferous age. In 1955, Clive Roderick Jones (1933–2022) discovered the first Malaysian graptolites on the small island of Pulau Tanjung Dendang, Langkawi, consequently demonstrating the presence of much older strata. The Early Paleozoic marine stratigraphy first discovered by C. R. Jones in the NW Malay Peninsula was subsequently recognized in other parts of SE Asia and became a characteristic element of the Gondwana-derived ‘Sibumasu’ terrane. This paper provides an account of the hidden history of the early discovery of graptolite fossils in Peninsular Malaysia after the re-examination of Jones’ graptolite fossils collection. The background to the events that led to this important finding, as well as its consequences for later stratigraphical research in Malaysia, were documented by Jones himself, complemented with the collection of field records, archives of papers and photographs. A biographical outline is presented of Jones and his career as a geologist in the Geological Survey Department of Malaya and his role in the development of geological research in Southeast Asia during the second half of the twentieth century.
PREHNITE – THE FIRST MINERAL DISCOVERED IN SOUTH AFRICA AND THE FIRST NAMED AFTER A PERSON
Authors: CAIRNCROSS BRUCE , MASTER SHARAD 
Published: November 2024

ABSTRACT
Prehnite is the first mineral discovered by Europeans in South Africa during the late 18th century, and the first mineral named after a person, Hendrik von Prehn, who allegedly discovered the mineral specimens. The acquisition of these specimens, their type-locality, and the processes in naming prehnite involved some of the leading scientists at that time. Various names had been proposed for prehnite including rochonite, emeraud du Cap, chrysolite, oisanite, prase, chrysoprase, shorle vert du Cap, until final acceptance in 1793 as prehnite. The district of Cradock in the Eastern Cape Province, South Africa is entrenched in the literature as the location of von Prehn’s specimens, yet no documentary evidence exists to support this claim. In contrast, several other prehnite occurrences are known from further inland, hosted in similar geological environments to those in the Cradock district, and it is concluded that the type-specimens came from one of these hinterland locations, within the Karoo Basin of South Africa.
Mapping the Nexus in the literature:The Influence of Entrepreneurial and Market Orientations on Supply Chain Agility
Authors: Lazarte-Aguirre Andrea 
Published: November 2024

Purpose – This study aims to map the relationship between entrepreneurial orientation (EO), market orientation (MO), and supply chain agility (SCA) from the operations perspective. An analysis of the most relevant manuscripts on the topic supposes a gap in the existing literature; thus, such an analysis was performed to evaluate consensus and discrepancies between scholars.
Design/methodology/approach – The literature review includes 13 papers published in Web of Science-indexed journals. These studies provide an overview of MO and EO on SCA. This review uses content analysis to map the nexus between these three capabilities.
Findings – The results indicate that the literature can be clustered in four areas: (a) MO and EO with supply chain agility, (b) MO and supply chain agility, (c) EO and supply chain agility, and (d) supply chain orientation and other orientations as a research niche. The literature confirms the dominance of EO and MO in achieving SCA and demonstrates their combined effect as a dual strategic orientation in an organization.
Originality/value – This study provides value to both researchers and policymakers in the areas of strategic management and supply chain by presenting the links between EO, MO, and SCA in a systematic and structured manner. In addition, it comprehensively identifies the gaps in previous research and provides avenues for future research.

The present study was designed with the objective of assessing the potential of size of dried blood spot (DBS) on a filter paper in predicting hematological attributes viz. RBC count, Hb, PCV and total protein (TP) in Cholistani cattle blood (n=71). A measured drop of blood was placed carefully on Whatman 42 filter paper and size was measured using ImageJ software. Results revealed that Hb had significant (P≤0.05) relation with size of the DBS. The regression equation between Hb and size of DBS was used to deduce	corrected Hb (CHb). The determined Hb and CHb were non-significantly (P≥0.05) different and had a strong agreement. It is concluded that the size of DBS is a substantially reliable predictor of Hb in cattle blood.
