description: It was usually assumed that the resonator based on a waveguide has the eigen oscillations that are formed by interference of two waves which propagate in different directions and have equal amplitudes. These patterns are usually called standing waves. We have shown that the eigen oscillations of a resonator which is filled by a layered dielectric can be base on the evanescent (non-propagating) waves. In some cases we need only one eigen wave to compose the eigen oscillation of a closed cavity.

description: We have formed a complete sample of 26 low redshift (z < 0.3) giant radio galaxies (GRGs) from the WENSS survey, selected at flux densities above 1 Jy at 325 MHz. We present 10.5-GHz observations with the 100-m Effelsberg telescope of 18 sources in this sample. These observations, together with similar data of the remaining eight sources, are combined with data from the WENSS, NVSS and GB6 surveys to study the radio properties of the lobes of these sources at arcminute resolution. We investigate radio source asymmetries, equipartition energy densities in the lobes, the presence of lobe pressure evolution with redshift, the spectral age and the density of the environments of these sources. We find that the armlength asymmetries of GRGs are slightly larger than those of smaller sized 3CR radio galaxies and that these are difficult to explain as arising from orientation effects only. We also find indications that the lobes of the GRGs, despite their large sizes, are still overpressured with respect to their environment. Further, we argue that any evolution of lobe pressure with redshift in these large sources is due to selection effects. A spectral ageing analysis suggests that the GRGs in our sample are the oldest members of the group of relatively high power radio sources whose radio powers have evolved to their currently observed lower values.

description: En el marco de la celebración de los diez años de la reforma al artículo 1o. de la Constitución Política de los Estados Unidos Mexicanos (CPEUM), publicada en el Diario Oficial de la Federación el 10 de junio de 2011, nuestro país trascendió a un Estado más garantista, pues reconoció el goce de los derechos humanos y se establecieron sus garantías.Este nuevo paradigma jurídico provocó cambios en la cultura jurídica en general y, particularmente, en las personas, comunidades y pueblos indígenas, ya que esta reforma implicó cambios sustantivos en el entendimiento y la interpretación de los derechos humanos. Esta cultura jurídica para los pueblos indígenas significó una nueva modalidad de hacer exigibles sus derechos humanos, tanto individuales como colectivos. El artículo 1o. de la Constitución federal ha fortalecido de manera especial la igualdad sustantiva y material de los pueblos indígenas, como fundamento de los derechos de igualdad y no discriminación; estos derechos deben ser considerados como un derecho transversal que debe ser vinculado con los derechos político-electorales de este grupo social.Esto es, la salvaguarda de la participación y representación política de los pueblos indígenas contribuirá a que este grupo social se introduzca en la arena política donde se toman las decisiones, sobre todo para que se inserten y formen parte de la esfera política, ocupando espacios para que tengan la oportunidad de discutir sobre su devenir, así como para buscar abatir los grandes retos y desafíos de sus derechos humanos. Esto es, se requiere garantizarlos, protegerlos y hacerlos exigibles.En este marco se reflexionará sobre los derechos de los pueblos indígenas en Baja California a la luz del decenio de la reforma al artículo 1o. de nuestra CPEUM y la exigibilidad de los derechos indígenas con base en la judicialización de los asuntos.

description: We calculated the optical excitation and thermal ionization energies of oxygen vacancies in m-HfO$_2$ using atomic basis sets, a non-local density functional and periodic supercell. The thermal ionization energies of negatively charged V$^-$ and V$^{2-}$ centres are consistent with values obtained by the electrical measurements. The results suggest that negative oxygen vacancies are the likely candidates for intrinsic electron traps in the hafnum-based gate stack devices.

description: The eruptive cycles of dwarf novae (DN) are thought to be due to a thermal-viscous instability in the accretion disk surrounding the white dwarf (WD). This model has long been known to imply a stress to pressure ratio α~0.1 in outburst compared to α~ 0.01 in quiescence. Such an enhancement in $α$ has recently been observed in simulations of turbulent transport driven by the magneto-rotational instability (MRI) when convection is present, without requiring a net magnetic flux. We independently recover this result by carrying out PLUTO MHD simulations of vertically stratified, radiative, shearing boxes with the thermodynamics and opacities appropriate to DN. The results are robust against the choice of vertical boundary conditions. The thermal equilibrium solutions found by the simulations trace the well-known S-curve in the density-temperature plane. We confirm that the high values of α~ 0.1 occur near the tip of the hot branch of the S-curve, where convection is active. However, we also present thermally-stable simulations at lower temperatures that have standard values of α~ 0.03 despite the presence of vigorous convection. We find no simple relationship between αand the strength of the convection, as measured by the ratio of convective to radiative flux. The cold branch is only very weakly ionized so, in the second part of this work, we studied the impact of non-ideal MHD effects on transport. We include resistivity in the simulations and find that the MRI-driven transport is quenched (α~ 0) below the critical density at which the magnetic Reynolds number R_m \leq 10^4. This is problematic as X-ray emission observed in quiescent systems requires ongoing accretion onto the WD. We verify that these X-rays cannot self-sustain MRI-driven turbulence by photo-ionizing the disk and discuss possible solutions to the issue of accretion in quiescence.

description: L-cysteine is one of the most promising biomass-based building blocks with great potential applications. Herein, we report a versatile synthetic route to produce cysteine-based diketopiperazine (DKP) with good yield from the thiol-ene click reaction of L-cysteine and commercially available acrylates, followed by dimerization of the amino acid intermediates. The achieved DKP diastereomers were successfully separated and fully characterized by spectroscopic methods. Moreover, the chiroptical property of DKP in the presence of various metal ions was investigated by circular dichroism spectroscopy. The potential application of the optically active cysteine-based DKP as a chiral probe for detection of silver ion in water has been demonstrated.

description: A nonlinear magnetoresistance - called unidirectional spin-Hall magnetoresistance - is recently experimentally discovered in metallic bilayers consisting of a heavy metal and a ferromagnetic metal. To study the fundamental mechanism of the USMR, both ferromagnetic and heavy metallic layer thickness dependence of the USMR are presented in a Pt/Co/AlOx trilayer at room temperature. To avoid ambiguities, second harmonic Hall measurements are used for separating spin-Hall and thermal contributions to the non-linear magnetoresistance. The experimental results are fitted by using a drift-diffusion theory, with parameters extracted from an analysis of longitudinal resistivity of the Co layer within the framework of the Fuchs-Sondheimer model. A good agreement with the theory is found, demonstrating that the USMR is governed by both the spin-Hall effect in the heavy metallic layer and the metallic diffusion process in the ferromagnetic layer.
Caught in the act - massive cluster formation at z=3-7 witnessed by APEX/ALMA
Creators: name: Weiss, Axel
Publisher: name: Zenodo
Year: 2019

description: Finding and tracing the progenitors of today's massive clusters is challenging but observations of these rare systems are rich in information on cluster assembly, including brightest cluster galaxy formation, the build up of the red sequence and intra-cluster light, heating and metal-enrichment in the forming intra-cluster medium, the triggering and quenching of both star-formation and of active galactic nuclei, and the in-fall of matter along filaments of the cosmic web. In a multi-band survey over 2500 deg2, the South Pole Telescope discovered a population of rare, extremely bright (S1.4 mm > 20 mJy) millimetre-selected sources. Our ALMA 870μm imaging showed that ∼ 90% of these sources are gravitationally lensed DSFGs at z ∼ 4. However, ∼ 10% of the SPT sources show no evidence for lensing but break-up into individual galaxies with ALMA and thus show all expected properties of the most active phase of early cluster formation predicted by cosmological simulations. The most spectacular example for this process identified in the SPT survey so far is SPT2349-56 at z = 4.3. This source is spatially well resolved at 870μm even with LABOCA/APEX and breaks up into 30 proto-cluster members with confirmed redshifts from ALMA. The entire system as a stunning SFR of 16500 M⊙ yr−1 and contains 15 (U)LIRGs at its core within a projected radius equal to the MW-LMC distance! In this talk I will present the latest result of our coordinated attempt to characterise all porto-cluster candidates discovered in the SPT survey.

Benchmark {\em ab initio} energy profiles for the gas-phase S$_N$2 reactions Y$^-$ + CH$_3$X $\to$ CH$_3$Y + X$^-$ (X,Y = F,Cl,Br). Validation of hybrid DFT methods

description: The energetics of the gas-phase S$_N$2 reactions Y$^-$ + CH$_3$X $\longrightarrow$ CH$_3$Y + X$^-$ (where X,Y = F, Cl, Br), were studied using (variants on) the recent W1 and W2 {\em ab initio} computational thermochemistry methods. Our computed benchmark data (including cases for which experimental data are unavailable altogether) are used to assess the quality of a number of semiempirical compound thermochemistry schemes such as G2 theory, G3 theory, and CBS-QB3, as well as a variety of density functional theory methods. Upon applying some modifications to the level of theory used for the reference geometry (adding diffuse functions, replacing B3LYP by the very recently proposed mPW1K functional), the compound methods appear to perform well. Only the 'half-and-half' functionals BH&HLYP and mPWH&HPW91, and the empirical mPW1K functional, consistently find all required stationary points; the other functionals fail to find a transition state in the F/Br case. BH&HLYP and mPWH&HPW91 somewhat overcorrect for the tendency of B3LYP (and, to a lesser extent, mPW1PW91) to underestimate barrier heights. The Becke97 and Becke97-1 functionals perform similarly to B3LYP for the problem under study, while the HCTH and HCTH-120 functionals both appear to underestimate central barriers. HCTH underestimates complexation energies; this problem is resolved in HCTH-120. mPW1K appears to exhibit the best performance of the functionals considered, although its energetics are still inferior to the compound thermochemistry methods.

description: The initiation or expansion of uranium mining in the Texas Gulf Coastal Plain, utilizing both open-pit and in situ leach methods, raises concerns about the potential impact on groundwater within mineralized aquifers. Understanding the hydrodynamics, hydrochemical evolution, and matrix geochemistry of these aquifers is essential for implementing effective protection and restoration measures. To address these issues, the Oakville Sandstone, a significant Coastal Plain aquifer, was chosen as a natural laboratory. The Oakville Sandstone comprises deposits from several major fluvial systems. The geometry and composition of these facies, along with superimposed structures and topography, play crucial roles in determining groundwater flux, aquifer transmissivity, and regional hydrochemical evolution. Groundwater flux patterns, especially in the shallow portions suitable for mining, can be highly complex and influenced by various factors. Studying the interrelationships among hydrodynamics, hydrochemical evolution, and matrix geochemistry in the Oakville Sandstone will provide insights into the effectiveness of mining technology in coastal plain aquifer systems. This research will aid in developing strategies to mitigate potential impacts on groundwater quality and ensure sustainable uranium mining practices in the region.

description: Chromium oxides, CrxOy, are of great interest due to the wide variety of their technological applications. Among them, CrO2 has been extensively investigated in recent years because it is an attractive compound to be used in spintronic heterostructures. However, its synthesis at low temperatures has been a difficult task due to the metastable nature of this oxide. This is indeed essential to ensure interface quality and the ability to coat thermal-sensitive materials such as those envisaged in spintronic devices. Pulsed Laser Deposition (PLD) is a technique that has the potential to meet the requirements stated above. In this work, we describe our efforts to grow chromium oxide thin films by PLD from Cr8O21 targets, using a KrF excimer laser. The as-deposited films were investigated by X-ray diffraction and Rutherford backscattering spectrometry. Structural and chemical composition studies showed that the films consist of a mixture of amorphous chromium oxides exhibiting different stoichiometries depending on the processing parameters, where nanocrystals of mainly Cr2O3 are dispersed. The analyses do not exclude the possibility of co-deposition of Cr2O3 and a low fraction of CrO2. PACS: 81.15.Fg, 75.50.Dd

description: The F and B matrices associated with Virasoro null vectors are derived in closed form by making use of the operator-approach suggested by the Liouville theory, where the quantum-group symmetry is explicit. It is found that the entries of the fusing and braiding matrices are not simply equal to quantum-group symbols, but involve additional coupling constants whose derivation is one aim of the present work. Our explicit formulae are new, to our knowledge, in spite of the numerous studies of this problem. The relationship between the quantum-group-invariant (of IRF type) and quantum-group-covariant (of vertex type) chiral operator-algebras is fully clarified, and connected with the transition to the shadow world for quantum-group symbols. The corresponding 3-j-symbol dressing is shown to reduce to the simpler transformation of Babelon and one of the author (J.-L. G.) in a suitable infinite limit defined by analytic continuation. The above two types of operators are found to coincide when applied to states with Liouville momenta going to $\infty$ in a suitable way. The introduction of quantum-group-covariant operators in the three dimensional picture gives a generalisation of the quantum-group version of discrete three-dimensional gravity that includes tetrahedra associated with 3-j symbols and universal R-matrix elements. Altogether the present work gives the concrete realization of Moore and Seiberg's scheme that describes the chiral operator-algebra of two-dimensional gravity and minimal models.

Subjects: subject: geology

subject: Texas

description: Of the approximately 153 billion barrels of oil discovered in Texas, conventional techniques and practices are estimated to recover around 33 percent, totaling about 51 billion barrels. If conventional recovery were to reach 40 percent of the original oil in place, which some consider possible, the total conventional production would be around 61 billion barrels. This leaves between 92 and 102 billion barrels of oil as conventionally unrecoverable. Nonconventional recovery methods could potentially target this substantial volume of oil, but the extent to which it can be recovered is a subject of debate among oil professionals. Estimates for nonconventional recovery range from as little as 5 percent to as much as 40 percent. Several factors contribute to this uncertainty, primarily concerning the spatial distribution and geologic occurrence of unrecoverable oil within known reservoirs. Historically, it was assumed that reservoirs and fluid distribution within them were uniform and homogeneous, leading to conventional field development based on a specified number of uniformly spaced wells. However, evidence suggests that many reservoirs exhibit significant geologic variations and compartmentalization, rendering uniform spacing inefficient in tapping and draining the reservoir efficiently. Untapped oil in these areas of geologic complexity is the potential target of strategic infill drilling. Conversely, residual oil remaining in portions of reservoirs that have already been tapped and drained during conventional primary and secondary production is the focus of enhanced or tertiary recovery technologies. These technologies aim to extract additional oil from already depleted reservoirs.

description: With rotating-wave approximation (RWA), we show in this paper that exciton transmission in a one-dimensional two-level molecule chain embedded in a cavity can be enhanced or suppressed by strong cavity-chain couplings. This exciton transmission is closely related to the number of molecules and the distribution of molecular exciton energy. In addition, we propose a proposal to enhance the exciton transmission by quantum-jump-based feedback. These results may find applications in experiments of exciton transmission in organic materials.

Cold molecular gas survives near R136 in 30 Doradus
Creators: name: Rubio, Monica
Publisher: name: Zenodo
Year: 2019

description: In the current paradigm of star formation, the densest regions of giant molecular clouds collapse into clumps, which eventually form Young Massive Clusters (YMC) which removes the molecular gas in its surrounding, decimating further star formation. Surprisingly there is cold molecular material very near (<10pc in projection) R136, the nearest YMC, located in the 30 Doradus star forming region in the metal-poor (0.5 Zo) LMC. According to most theoretical predictions, the photo-ionizing luminosity of the cluster is sufficient to evacuate any dense molecular gas surrounding the cluster within ~1 Myr. We present high spatial resolution ALMA maps in CO(3-2) that resolve the spatial structure of the cold gas. We determine their velocity distribution and the density of the molecular gas near R136 from the high density tracer CS(7-6) map and derive the molecular cloud properties in this extreme environment. We explore the origin of this weak cold CO gas and analyze if these represent molecular clumps (gas mass ~ 10^3 Mo) driven by the outwards wind momentum or VERY DENSE clumps that have survived photo-dissocia

description: We propose large-core correlation-consistent pseudopotential basis sets for the heavy p-block elements Ga-Kr and In-Xe. The basis sets are of cc-pVTZ and cc-pVQZ quality, and have been optimized for use with the large-core (valence-electrons only) Stuttgart-Dresden-Bonn relativistic pseudopotentials. Validation calculations on a variety of third-row and fourth-row diatomics suggest them to be comparable in quality to the all-electron cc-pVTZ and cc-pVQZ basis sets for lighter elements. Especially the SDB-cc-pVQZ basis set in conjunction with a core polarization potential (CPP) yields excellent agreement with experiment for compounds of the later heavy p-block elements. For accurate calculations on Ga (and, to a lesser extent, Ge) compounds, explicit treatment of 13 valence electrons appears to be desirable, while it seems inevitable for In compounds. For Ga and Ge, we propose correlation consistent basis sets extended for (3d) correlation. For accurate calculations on organometallic complexes of interest to homogenous catalysis, we recommend a combination of the standard cc-pVTZ basis set for first- and second-row elements, the presently derived SDB-cc-pVTZ basis set for heavier p-block elements, and for transition metals, the small-core [6s5p3d] Stuttgart-Dresden basis set-RECP combination supplemented by (2f1g) functions with exponents given in the Appendix to the present paper.

Observing the collimation and acceleration region of AGN jets with the GMVA+ALMA at 3 mm

description: The inclusion of beamformed ALMA in the Global Millimetre VLBI Array (GMVA) has enhanced the 3-mm network with a factor 2-3 in resolution in the North-South direction, a duplication of the sensitivity, and an important enhancement also in image fidelity. Submilliarcsecond resolution imaging in Band 3 does not only provide key information about the scattering pattern and the innermost morphology of Sgr A*, but also reveals the structure and profile of the regions where jets collimate and accelerate from the central powering super massive black hole, and provides invaluable priors for complementary observations at a shorter wavelength, also including beamformed ALMA. The GMVA has performed observations together with ALMA in Cycle 4 (targets were Sgr A*, 3C 273, and OJ 287), Cycle 5 (Sgr A*, M 87, 3C 279, 3C 273, and OJ 287), and Cycle 6 (3C 345, OJ 287, OR -017). We will present selected highlights from these results and discuss the scientific and observing opportunities open for the near .

description: We report a different type of three-minute chromospheric oscillations above a sunspot in association with a small-scale impulsive event in a light bridge. During our observations, we found a transient brightening in the light bridge. The brightening was composed of elementary bursts that may be a manifestation of fast repetitive magnetic reconnections in the light bridge. Interestingly, the oscillations in the nearby sunspot umbra were impulsively excited when the intensity of the brightening reached its peak. The initial period of the oscillations was about 2.3 minutes and then gradually increased to 3.0 minutes with time. In addition, we found that the amplitude of the excited oscillations was twice the amplitude of oscillations before the brightening. Based on our results, we propose that magnetic reconnection occurring in a light bridge can excite of oscillations in the nearby sunspot umbra.

description: We report for the first time real time in situ and quantitative measurements of the mutarotation reaction of lactose in the solid state. The experiments have been performed by 13C NMR. We show that mutarotation is initiated on heating the amorphous state, and reaches chemical equilibrium close above the glass transition temperature Tg. We do not observe this transformation when starting from stable crystalline states. The final ratio of and anomers is 1:1, which suggests that the energy profile of the mutarotation reaction pathway in the solid state is actually different from the mechanism proposed for aqueous solution. This chemical equipartition is reached before the crystallization into the corresponding 1:1 molecular compound. These new data clearly illustrate the interrelation between the chemical molecular properties, the physical state of the material, and the relaxational dynamics of the glass.
On the size of the CO-depletion radius in the IRDC G351.77-0.51

description: We present a study of the depletion of CO in the IRDC G351.77-0.51. Knowledge of the degree of CO-depletion provides information on the physical conditions occurring in the innermost and the densest regions of molecular clouds. A key issue is the radius within which the CO is depleted (Rdep). To estimate the depletion map on the cloud scale, we use the dust continuum (Hi-Gal), combined with APEX C18O(2-1) line observations. We built a simple model to investigate the size of the CO-depleted region in G351. The model suggests that Rdep is lower than 0.12 pc where n(H2) is larger than 3 x 10**4 cm**-3. These results provide crucial information on the spatial scales on which different chemical processes operate in high-mass star forming regions and also presents a warning for using CO for kinematical studies in IRDCs.

description: Tourism and Travel stores offering a huge quantity of services and traveling information by online. Additionally, this huge volume of information smoothly accessed by electronic devices, like phone, computer with the availability of internet connection. When tourists are visiting any cities, most of them aimed to explore the interesting fact or things about the places and events etc. in spite of the fruitful progress there are still several opportunities remaining to discover. Firstly, we investigate the properties of the travel package and expand TAST (Tourist-Area-Season topic) model. Thereafter, we expand the Tourist Area-Season topic (TAST) model for confining the relationship over the every group of the tourist. This research work expressing an outline for the recommender system and describing the latest production of recommendation techniques that are generally divided in the three phase: Collaborative, Hybrid recommendation and Content-based approaches. Finally, we appraise the TouristArea-Season topic (TAST) model with the cocktail recommendation approach on the real-world travel package data

description: Time evolution of initially prepared entangled state in the system of coupled quantum dots has been analyzed by means of two different theoretical approaches: equations of motion for the all orders localized electron correlation functions, considering interference effects, and kinetic equations for the pseudo-particle occupation numbers with constraint on the possible physical states. Results obtained by means of different approaches were carefully analyzed and compared with each other. Revealed direct link between concurrence (degree of entanglement) and quantum dots pair correlation functions allowed us to follow the changes of entanglement during time evolution of the coupled quantum dots system. It was demonstrated that the degree of entanglement can be controllably tuned during the time evolution of quantum dots system.

Testing the robustness of massive black hole mass measurements using ALMA and MUSE
Creators: name: Thater, Sabine
Publisher: name: Zenodo
Year: 2019

description: By now about hundred massive black hole (MBH) mass measurements of local galaxies based on stellar or gaseous motion reveal strong correlations of the MBH mass with their bulge properties, such as bulge mass, stellar velocity dispersion (sigma) and light concentration. Determining MBH masses is a challenging procedure and it is not possible to use one single method across the full sample of galaxies. Problematically, measurements from different dynamical tracers often give discrepant results , rising the question whether the variety of methods forces an additional bias on the scaling relations. Therefore, connecting mass results from different methods is necessary to evaluate the robustness and universality of the measurement results and thus crucial for improving the understanding of the interplay between the central black holes and their host galaxies. I will present our two independent black hole determinations from the early-type galaxy NGC 6958 based on stellar kinematics (MUSE) and molecular gas kinematics (ALMA), taking special care in revisiting the associated measurement errors, specifically, the systematics associated with the dynamical methods, and the general accuracy of black hole mass measurements. NGC 6958 is part of the SMASHING sample of 20 early-type galaxies which expand the scaling relations on both the high and low mass end. I will conclude my talk with discussing our recent results in context of the MBH mass-sigma relation

description: Hyperbolic metamaterials (HMMs) are the cornerstone of the hyperlens, which brings the superresolution effect from the near-field to the far-field zone. For effective application of the hyperlens it should operate in so-called canalization regime, when the phase advancement of the propagating fields is maximally supressed, and thus field broadening is minimized. For conventional hyperlenses it is relatively straightforward to achieve canalization by tuning the anisotropic permittivity tensor. However, for a dark-field hyperlens designed to image weak scatterers by filtering out background radiation (dark-field regime) this approach is not viable, because design requirements for such filtering and elimination of phase advancement i.e. canalization, are mutually exclusive. Here we propose the use of magnetic ($μ$-positive and negative) HMMs to achieve phase cancellation at the output equivalent to the performance of a HMM in the canalized regime. The proposed structure offers additional flexibility over simple HMMs in tuning light propagation. We show that in this ``pseudocanalizing'' configuration quality of an image is comparable to a conventional hyperlens, while the desired filtering of the incident illumination associated with the dark-field hyperlens is preserved.

description: Research on tight gas sands has traditionally focused on lenticular sands, but blanket-geometry sands, deposited by different processes, present distinct external and internal reservoir geometries requiring unique exploration and production techniques. To ensure the applicability of research findings across various reservoirs, a survey was conducted with a focus on elastic depositional systems and the potential transferability of results between different stratigraphic units. Based on the survey results, five stratigraphic units were selected for further study, and data collection efforts were initiated during the contract period. A comprehensive work plan was developed for the analysis of these units, which includes the preparation of geologic cross sections and maps, review of productive areas, resource analysis, and documentation of findings. The five selected units for study are the Travis Peak Formation, the Corcoran and Cozzette Sandstones, the Mancos "B" interval of the Mancos Shale, the upper Almond Formation, and the Frontier Formation. Data collection efforts have yielded a significant number of well logs from Colorado and Wyoming, with additional logs identified from Bureau files for the Travis Peak Formation. Wells suitable for cross-sectional analysis have been identified for the Travis Peak and Corcoran/Cozzette trends, and initial cross sections have been prepared for the latter trend. These efforts aim to enhance understanding and exploration potential of blanket-geometry tight gas sand reservoirs.

description: The mapping of high resistivity cap rock shales in the Frio Formation along the Texas Gulf Coast reveals variations in thickness and distribution between the upper and lower regions. Thinner cap rock is observed in the upper Texas Gulf Coast, while thicker and more extensive cap rock is present in the lower Texas Gulf Coast. This variation correlates with increases in maximum shale resistivity, the presence of unstable minerals such as volcanic rock fragments and detrital carbonate grains, and authigenic cementation, all of which are more pronounced in areas with thicker cap rock in the lower Gulf Coast. However, the distribution of cap rock in two major Frio deltaic depocenters does not show clear similarity. Facies analysis of regional cross sections in the lower Texas Gulf Coast, particularly in the Sarita East field of Kenedy County, indicates the preferential development of cap rock in the delta-front/slope facies of the Norias delta system. The sand content within the cap rock interval varies, suggesting that sands within the cap rock may serve as fluid conduits during mineralization processes. Cap rock is less commonly developed in the shale-rich prodelta and distal delta-front facies. While high resistivity cap rock shales have been attributed to authigenic calcite cementation, conclusive evidence for this origin is lacking. Preliminary mineralogic analyses of well cuttings have not provided satisfactory results, highlighting the need for core analysis through cap rock and non-cap rock intervals to determine mineralogic variability and accurately assess any mineralogic control over the high resistivity log response. Further investigation is necessary to better understand the origin and characteristics of high resistivity cap rock shales in the Frio Formation.
