Askarova N. S. Feature space of the Atasu type deposits (Сentral Kazakhstan) [Електронний ресурс] / N. S. Askarova, A. T. Roman, V. S. Portnov, A. N. Kоpobayeva // Naukovyi visnyk Natsionalnoho Hirnychoho Universytetu. - 2021. - № 5. - С. 5-10. - Режим доступу: http://nbuv.gov.ua/UJRN/Nvngu_2021_5_3 Purpose. Studying geological formations of the Atasu type deposits to identify prospecting criteria. Methodology. Analysis of literature and fund materials, comparative analysis of geological factors characteristic of stratiform ores, stage formation and metamorphism. Findings. The main features characteristic of the deposits of the Atasu type have been formed: their belonging to the lower strata of the Upper Famennian, Upper Devonian to the Visean stage of the Lower Carboniferous; complex composition of ferromanganese and polymetallic ores formed in three hydrothermal stages (sedimentary, metasomatic and vein ones), stratiform, lenticular, localized near volcanic edifices. Originality. The main geological criteria have been established that determine the belonging of the Uspensky ore belt in Central Kazakhstan deposits to the stratiform deposits of the Atasu type formed at different depths in continental rift valleys. The criteria include the age interval of the formation of ore deposits of the stratiform type, hydrothermal staging of mineralization (sedimentary, metamorphic, metamorphic (hydrothermal, dislocation multistage and dynamothermal)); localization of folded and post-folded subvolcanic intrusions near former volcanic edifices. Practical value. The main prospecting geological criteria (features) established for the Atasu type deposits can be used to form a feature space for predicting the areas of mineral deposits localization of the Uspensky ore belt of Central Kazakhstan formed in close time periods, in similar geological-geochemical, thermodynamic and geodynamic conditions. | ||

Roman A. T. Tectonic peculiarities of the Zhailma structure formation [Електронний ресурс] / A. T. Roman, V. S. Portnov, N. S. Askarova // Naukovyi visnyk Natsionalnoho Hirnychoho Universytetu. - 2022. - № 3. - С. 11-16. - Режим доступу: http://nbuv.gov.ua/UJRN/Nvngu_2022_3_4 Purpose. Studying the genesis and position of the Zhailma trough in the tectonic structures of Central Kazakhstan. Methodology. Critical analysis of literature and stock materials, comparative analysis of geological, geophysical and morphological factors characteristic of continental rifts, features of the formation of volcanic graben synclines, analysis of the results of isotope dating of rocks. Findings. The Zhailma graben-syncline is not an independent structure of the rift origin. The formation of Zhailma is associated with the general evolution of the Sarysu - Teniz segment of the Devonian volcano-plutonic belt. The formation of the Zhailma graben syncline is associated with subsidence after ejections of significant masses of felsic magmatic material. Originality. The authors carried out a comparative analysis of the geological, geophysical and morphological data of the Zhailma structure with similar data characteristic of modern continental rifts. As a result of the analysis, it was established that the rift genesis of Zhailma remains controversial. This structure developed simultaneously with the Devonian volcanic-plutonic belt, and is genetically related to the processes of volcanism. The authors suggest that Zhailma is a volcanic graben-syncline. Practical value. Over a long period of studying the structure, an opinion was formed about the futility of the Sarysu-Teniz segment of the Devonian volcano-plutonic belt for the identification of industrial deposits. An exception was the Zhailma trough, which is a unique Famennian-Carboniferous sedimentary structure in terms of ore saturation, containing significant reserves of iron-manganese, barite-polymetallic and barite proper ores. In this connection, the authors consider it practically important to study the existing graben-synclines in the area of the Devonian volcano-plutonic belt in order to identify industrial deposits of the Atasu type. | ||

Malchenko E. G. On the possible role of magmatism in the atasu type strathiform mineralization (Central Kazakhstan) [Електронний ресурс] / E. G. Malchenko, A. T. Roman, V. S. Portnov // Naukovyi visnyk Natsionalnoho Hirnychoho Universytetu. - 2022. - № 2. - С. 11-16. - Режим доступу: http://nbuv.gov.ua/UJRN/Nvngu_2022_2_4 Purpose. Studying the geological features of large industrial "Atasu type" ore objects. Methodology. Critical analysis of literature and stock materials, comparative analysis of geological factors characteristic of stratiform ores, stages and peculiarities of formation depending on the processes of volcanism, analysis of the results of isotope dating of rocks. Findings. Participation of volcanism (magmatism) processes in forming deposits of ferromanganese and barite-polymetallic ores of the Atasu type was minimal. It was expressed only in the development of a dissected pre-Famennian paleorelief favorable for the accumulation of metal-bearing silts and in the development of local hydraulic seals, which made it possible for the metal-bearing waters to circulate. Magmatic formations are protrusions of more ancient pre-Famennian Givetian - Franian volcanic structures. Originality. The pre-ore age of subvolcanic intrusions partially confirmed by the results of determining the absolute age, from the samples taken in the quarry of the Ushkatyn-deposit that amounted to 373 +- 4 million years, which corresponds to the middle of the Frasnian stage. The presence of three Atasu type ferromanganese deposits in the amagmatogenic Aidagarly graben-syncline also confirms this hypothesis. The genesis of deposits of the Atasu type is considered as sedimentary-hydrothermal one, associated with the processes of diagenesis and catagenesis. Practical value. Predicting the possibility of finding deposits of the Atasu type in graben-synclines throughout the entire area of the Devonian volcano-plutonic belt. | ||

Malchenko E. G. Peculiarities of the formation of the Zhailma volcano-tectonic deep [Електронний ресурс] / E. G. Malchenko, A. T. Roman, V. S. Portnov, N. S. Askarova // Naukovyi visnyk Natsionalnoho Hirnychoho Universytetu. - 2023. - № 1. - С. 26-31. - Режим доступу: http://nbuv.gov.ua/UJRN/Nvngu_2023_1_6 Purpose. Studying the features of the Zhailma volcano-tectonic depression formation, as well as the principles and factors affecting this structure's ore formation. Methodology. Analysis of the results of isotope dating of rocks, critical analysis of literature and fund materials, analysis of the genesis and specificity of the Zhailma structure mineralization, features of the volcano-tectonic depression formation. Findings. The Zhailma graben syncline formation is associated with subsidence after ejections of significant masses of acidic magmatic material from stratovolcanoes concentrated on the Zhailma structure. The initiation and development of the graben-syncline is closely related to the processes of tectonomagmatic evolution of the Devonian volcano-plutonic belt. Originality. The search model for stratiform deposits of the Atasu type has been revised, taking into account the original theory of the volcano-tectonic origin of the structure, formed at the final stages of the formation and development of the Devonian volcano-plutonic belt. The genesis of the Atasu-type deposits is considered as sedimentary-hydrothermal one, associated with the processes of diagenesis and catagenesis occurring within sedimentary basins. The presence of two large volcanoes on the northern side of the caldera structure was substantiated: North Zhairem and Ustanynzhal. Practical value. It is recommended to carry out predictive metallogenic and, accordingly, prospecting work for deposits of the Atasu type within the graben-synclines of the Sarysu - Teniz segment of the Devonian volcanic belt, where such deposits of ferromanganese ores as Tur, Bogach and Karaadyr are already being developed in the Aydagarly graben-syncline. | ||
