The middle of the Salair peneplanation planes is widely distributed here – the Late Cretaceous-Early Paleogene, formed at elevations slightly exceeding the denudation basis – the level of the World Ocean at that time, which was 250 m above the modern one. Its current absolute marks are about 400 m, that corresponds to the neotectonic rise of the territory with an amplitude of 150 m. At the beginning of the Quaternary,a vigorous downcutting of hydrographic network occurred with its stabilization and transition to a perstratal regime at elevations 10–15 m below the сurrent encroachment line of stream flows as a result of neotectonic bulging up of the territory and further drawdown in the level of the World Ocean. Massive deposition of aeolian material occurred in the Middle Quaternary. The thickness of the cover loams on watersheds is currently up to 55 m. From valley slopes aeolian loams entered the hydraulic network and overlapped the Early Quaternary alluvium, with which the main gold-bearing alluvial placers of the territory are associated. During reoccurring downcutting, there was an abstraction of watercourse heads of the southwestern slope by watercourses of the northeastern slope of Salair with a displacement of the main watershed in some areas by 5–6 km to the southwest. Emerging buried areas of paleovalleys represent prospective targets in search for placers. The hydrographic network that arose during reoccurrung downcutting does not repeat in detail the Early Quaternary one and ancient alluvium oft en underlays slope deposits with a displacement beyond the bottom of modern valleys to the first tens of meters. Conducting a large-scale geomorphological survey makes it possible to identify areas of ancient valleys with potentially gold-bearing alluvium, which usually remain untested during prospecting and exploration.","PeriodicalId":52268,"journal":{"name":"Geology and Mineral Resources of Siberia","volume":"27 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139188770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The absolute age of monzogabbroes of the stock intrusion lower phase is defined as 397 Ma, that corresponds to the Lower Devonian. Nd-model age of protolith during melting of gabbroids composes 893 Ma, that is characteristic of transit zone from the Middle Paleozoic consolidation to the Altai – Mongolian terrain. According to the chemistry, the Timofeev stock rocks belong to the lime-alkali and shoshonite series. The geodynamic aspect of melt generation is interpreted by mixing alkaline oceanic basalts of the plume setting and normal oceanic basalts of mid-oceanic ridges that took place in the Paleo-Asian Ocean evolution in the Early Paleozoic. Samarium-neodymium isotopic labels of gabbroids indicate the proximity of their values to chondrite meteorites. The ratio of neodymium isotopes with gabbro age indicates that the isotopically varying earth’s crust, close to the depleted mantle, existed under the Korgon trough in the Early Paleozoic. The skarn-iron-ore deposit of the same name is spatially and paragenetically connected with the Timofeev stock.","PeriodicalId":52268,"journal":{"name":"Geology and Mineral Resources of Siberia","volume":"33 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139189469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The identical mineral composition of gold-sulphide formations developed by Early Proterozoic rocks of the Eekitian series and rhyolites of the same age gave reason to assume the simultaneity of their formation and to refer them to the general stage of ore formation. According to the established mineral paragenesis, described gold sulphide manifestations are attributed to the gold-quartzsulphide formation type. The discovery of gold sulphide mineralization in the zone of tectonic fracturing of Early-Middle Permian sandstones indicates the formation of ore occurrences in the area associated with the processes of tectonomagmatic activation of the Mesozoic. The identification of indicators of low-temperature hydrothermal processes as mineral paragenesis – mercury-containing gold, cinnabar and barite, testifies to shallow and low-temperature conditions for the formation of this ore manifestation. It was found that according to the Co/Ni ratio, 28% of pyrites (including gold-bearing ones) are associated with hydrothermal processes. In general, the detection of native gold in quartz veins in free form and as microinclusions and impurities in pyrite, as well as the discovery of relatively large poorly rounded attachments of gold to quartz in stream flows dewatering the studied ore formations, allows researchers to positively assess the prospects for further study of ore manifestations of the Sololi uplift of the Olenek arch.","PeriodicalId":52268,"journal":{"name":"Geology and Mineral Resources of Siberia","volume":"17 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139189240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the CO2 solution is saturated, along with an increase in total dissolved solids there is a naturally-determined increment in the volume of transition of ions into their complex forms. The main macro components (Ca2+, Mg2+, Na+, K+, (SO4)2–, Cl– ) migrate mainly in the form of their own ions, with a decrease in their fraction by an order of 1–3 % with an increase in mineralization. Ions such as Fe, Al3+, Mn3+, (NO3)–, (HCO3)–, SiO2, (NH4)+, (NO2)– are prone to transition into the form of complex compounds, the fraction of which in the total volume increases with the amount of saturation of solution with carbon dioxide. When CO2 is injected into the terrigenous reservoir, there is a natural decrease in the solution pH, absence of precipitation of carbonates and minimal changes in the rock porosity. The observed process of dissolution of primary aluminosilicate minerals (albite, anorthite, potassium feldspar) is characteristic of most of the considered mineralogical varieties of reservoirs, when they are saturated with CO2. This process is accompanied by deposition of secondary mineral phases in the form of montmorillonites, illites, chlorites, etc. Taking into account the low rates of these reactions, no significant changes in reservoir properties are noticed.","PeriodicalId":52268,"journal":{"name":"Geology and Mineral Resources of Siberia","volume":"33 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139192853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main minerals of the peat ash part are mica, quartz, plagioclase, bassanite, potassium feldspar; secondary one is chlorite, accessory ones are amphibole, illite. The study results of peat substance by energy-dispersive X-ray microanalysis showed that peat deposits are represented by a mixture of particles and conglomerates of various shapes and sizes. The elemental composition of the main matrix of samples is presented by an organic component with a high content of C and O and silicate mineral component with a content of Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe. Single small bright particles of facetted and semi-facetted shape with a high content of Fe, Ti, Ca, Ba and W occur in almost all studied peat samples. The mineral component of these particles may be represented by magnetites, titanites, single metal granules. The upper interval of the peat bog section (0-20 cm) is characterized by increased concentrations of Cu and Zn, that may be due to both anthropogenic stress on swamp ecosystems and high biophillyng, i.e. the ability to accumulate living matter.","PeriodicalId":52268,"journal":{"name":"Geology and Mineral Resources of Siberia","volume":"27 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139195886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
