The data obtained are compared with temperature measurements on a calcite/dolomite thermometer performed earlier. It is assumed that the non-linearity of the dependence between the amount of heating of sedimentary strata and the power of intrusiv is associated with the heterogeneity of the section in the mineral composition of various layers, their thickness and the amount of organic matter contained in them. Based on this, it is proposed to use the temperature of decomposition of carbonates, taking into account pressure, as the maximum temperature of contact metamorphism, laid down in the physico-chemical justification of the mathematical model. The process proceeds with an increase in the void space due to losses during calcination and the formation of a fracturing system, the scale of development of which has a direct impact on the transformation of rocks, including located far from the intrusion.","PeriodicalId":13672,"journal":{"name":"Interexpo GEO-Siberia","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82568815","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}

In these conditions the facies analysis is of paramount importance: both in traditional for sedimentary strata and in its refined or new modifications. Most often, the sedimentological study uses the developments known as the facies-cyclic analysis, which predetermines a clear methodology of research, providing for a sequential separation of facies - establishment of cycles - correlation of sections - paleogeographic reconstruction, with obligatory \"reverse\" verification of constructions at each successive stage. However, in today's reality, the classical study of oil and gas exploration and production is practically impossible because of incomplete core sampling, fragmentation of its removal, a priori insufficient amount of core material, especially for unproductive horizons. With the mentioned non-compliance of facies-cyclic \"canons\" it is suggested to realize direct and direct use of facies studies, realized on the borehole cores for sedimentological and petrophysical modeling of geological natural systems. Thus, consciously removing the problems associated with the allocation of cycles, diachrony of layers of migratory nature, thus having a direct transition to the solution of practical oil and gas problems, based on a reliable facies basis. The method is developed for deep productive horizons, inaccessible to direct observation, in conditions of limited actual data (small number of cores).","PeriodicalId":13672,"journal":{"name":"Interexpo GEO-Siberia","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90969395","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}

Based on the use of unified lithological criteria, taking into account geophysical and paleontological-stratigraphic data, the lower four out of six members identified within the Bazhenovo Formation in the Central Region of Western Siberia were traced in the studied area. In the Southeastern region, members 1-4 constitute the entire Bazhenovo Formation, which corresponds here to most of the Volgian-lower part of the Ryazanian. At the end of the Middle Volgian time, an increase in the supply of clay material to the study area is noted due to the proximity of this area to sediment sources and some decrease in global sea level. The depositional environments of the Bazhenovo Formation in the Southeastern region were suboxic during the Middle Volgian and changed to anoxic in the Late Volgian-first half of the Ryazanian. The development of suboxic conditions in the second half of the Ryazanian led to the cessation of the accumulation of Bazhenovo deposits in the studied area.","PeriodicalId":13672,"journal":{"name":"Interexpo GEO-Siberia","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87818059","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 approach consists in revealation of statistically significant correlations between long time series of key parameters of these processes, recorded in different spatial regions of target object. Within the framework of this approach, a space-time analysis of technogenic seismicity (hypocenter coordinates, time and energy of weak and moderate dynamic events) at the Tashtagol iron ore deposit was performed in conjunction with geomechanical modeling of the stress field evolution due to mining. Using the obtained correlation dependences between the number of dynamic events and the integral characteristic of the stress state, a forecast was made for the number of dynamic events in different areas of the geomechanical space of the deposit under various mining technologies. Comparison of the results shows that due to backfill array construction, as a rule, the level of seismic activity decreases.","PeriodicalId":13672,"journal":{"name":"Interexpo GEO-Siberia","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81230606","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}

It has been established that the background concentrations of chemical elements in surface and ground waters decrease in the order from Si to In. Hydrogeochemical anomalies were established in the distribution of As, U, Ti, Li, Al, Si, Mn, Fe, Br, I, Sb, which served as the basis for compiling a map of the degree of pollution of the natural waters of the city of Novosibirsk. Among the surface waters, the most polluted are the waters of the rivers: Inya (near the village of Novolugovoe), 2nd Eltsovka (near the Chemical Concentrates Plant), Plyushchikha (near Vilyuiskaya Street), Eltsovka (in Nizhnyaya Eltsovka), Kamyshenka (in Inyushensky Bor), as well as rivers Ob (in the Zaeltsovsky forest). It should be noted that the concentrations of hazardous elements in the Kamyshenka, Plyushchikha and 2 Eltsovka rivers decrease towards their mouths. The least polluted with toxic elements were the waters of the Tula and Kamenka rivers, the studied lakes and backwaters, the Gorsky and Tulinsky flooded quarries, as well as the samples taken in the standpipe near the Bugrinsky bridge.","PeriodicalId":13672,"journal":{"name":"Interexpo GEO-Siberia","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88231230","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}
