A new basic copper sulfamate Cu₃(OH)₅[SO₃(NH₂)] of the anthropogene origin from the oxidation zone of the Murzinskoe gold deposit (Altai Krai, Russia) has been characterized with XRD and IR spectroscopy. This compound has not natural or synthetic analogue and represents a novel structure type. It is monoclinic, space group P2₁/c, a = 7.5817(4); b = 5.9823(3); c = 17.0084(8) Å; = 99.140(5)°; V = 761.63(7) Å³ ; Z = 4. The crystal structure of this sulfamate (R = 4.91%) is based on the distorted brucite-type layers built by Cu2⁺-centred octahedra of three different types: CuO₂(OH)₄, Cu(OH)₆ and CuO(OH)₅. Isolated from each other SO₃NH₂ tetrahedra are linked to the layers from both sides. The neighboring heteropolyhedral layers formed by Cu-centred octahedra and SO₃NH₂ tetrahedra are connected via the system of hydrogen bonds.

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.

The problem of the interaction of spreading ridges with large igneous provinces is widely discussed in the scientific literature. The most striking and well-preserved example of such interaction in the geological past is the “collision” of the Southeast Indian spreading ridge and the Kerguelen plateau, which occurred about 43 Maago. The consequence of this event was the division of a single Kerguelen plateau into two parts: in fact, the Kerguelen plateau and the Broken ridge. The conditions for the formation of these morphostructures were studied experimentally. The paper presents the results of modeling the interaction of a spreading ridge with a large igneous province. The experimental results correlate well with geological and geophysical data and with the proposed model for the development of this region.

According to drilling data, the internal structure of the Mozyr salt cryptodiapir has been reconstructed, the main elements of which are strongly compressed folds with radially arranged layers on the wings, complicating domes and inter-dome depressions, flexures. A high degree of interrelation between the modern relief and the cryptodiapir roof buried at a depth of several hundred meters has been established. It is explained by the continued mobility of salts at the present stage. This feature allows us to supplement the structural and geological data with the results of morphostructural analysis of the relief and to identify certain elements of order in the structure of the Mozyr dome.

The presented article is devoted to the actual problem of regional geology — the reconstruction of the history of geological development of the Upper Paleozoic-Triassic complex in the southern part of the North Caspian. Understanding of evolution is one of the necessary conditions for improving the reliability of predicting the geological objects characteristics, the structure of which determines the possibilities for the formation of hydrocarbon accumulations. Despite the rather limited data presented mainly by 2D seismic, the authors created a tectonostratigraphic model of the region. It is based on the results of integrated interpretation of geological and geophysical information, carried out using modern methodological approaches.

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.

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).

A sedimentation model of the formation of the carbonate bundle of the Bogdinsky formation (Lower Triassic) of the location of the tetrapod Bolshoe Bogdo II is proposed. The genesis of microcrystals of analcime obtained from bone-bearing limestone with the remains of the temnospondyl amphibian Inflectosaurus sp was established during lithological-facies, diffractometric, crystallographic analyses, as well as the study of the grinds. The formation under consideration is associated with the possible transformation of the pyroclastic material of the Siberian trap province.

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.

The article presents the mineralogical and geochemical features of the types and grades of ores of the Yоshlik copper-molybdenum deposit. Chemical, mass spectrometric results of analyses of the selected samples are given. Ore minerals and their structural and textural features are established in the description of the anschlifs. The formation of the Yоshlik deposit is associated with small intrusions of diorites and mainly monzodiorites and monzonites, since it is polychronous and polyformational like other copper-porphyry objects of the Almalyk ore region. There is a possible connection between the mineralization of gold, silver and platinoids with plutonic dyke formations.

In the article, methods of mathematical statistics were used to study the processes of sedimentogenesis and early diagenesis of the surface sediments of the Kara Sea. Correlation analysis established two groups of oxides associated with certain granulometric types of deposits. As a result of applying one-way analysis of variance, the regularity of the distribution of sand, silt and pelite was established in accordance with the conditions of sedimentation based on differences between their average values. Based on these data, maps of the distribution of sand, silt, and pelite were constructed within the studied part of the Kara Sea. On the basis of statistical data, some features of the main factors of sedimentogenesis for this region were revealed. As a result of the established relationship between the Mn/Al, Mn/Fe, MnO/SiO2 ratios and depth, using a one-dimensional regression analysis, the intensity of early oxidative diagenesis within the shelf zone of the Kara Sea was studied.

The sections of boreholes and sediment cores in the Taman shelf area and on the Caucasian continental slope, which uncovered shallow and deep-water facies of the interglacial Karangate horizon, were studied. The shallow-water sediments include clayey and sandy-shell varieties containing stenohaline marine molluscan fauna. Deep-water sediments are represented by sapropelic and coccolithic layers with a marine flora of diatom algae and coccolithophorids.

The article presents modern data on the chemical, gas composition, the content of the stable isotopes of oxygen, hydrogen, carbon and sulfur in the natural mineral waters of the Essentuki field. A detailed study of the geological and hydrogeological features of the water circulation territory, their macro components composition, the content of organic matter in the water, temperature conditions and values of δ¹⁸О_SMOW, δD_SMOW, δ¹³СDIC, δ18О_DIC, δ³⁴S_VCDT, δ¹³C_CO2, δ¹³C_CH4, δ¹⁵N revealed the genesis of the aqueous, gas and salt components of the natural mineral waters of the Essentuki field. Established that all natural mineral waters of the Essentuki field are meteoric infiltration waters. The heterogeneous component composition of the natural mineral waters, that circulate in various aquifers, represents the features of the lithological composition of the water-bearing rocks, the degree of openness or closeness of faults and the intensity of reactions in the water-rock-gas-organic matter system.
