According to the chemical composition of the studied mud volcanic waters are represented by Na-Cl and Na-HCO3-Cl types, and the Cl/Br, Na/Cl, and Y/Ho ratios specify three main genetic groups of volcanoes. It was found that the rare-earth element contents in the aqueous phase of mud volcanoes are low (fractions of μg/L) and are distinguished by negative cerium anomalies and positive europium and holmium anomalies. The highest REE concentrations are observed in mud volcanoes located within the oldest Cretaceous sediments in the area of fault influence. As the distance from the Mesozoic source ΣREE sharply decreases. It has found that the free CO2 content in the aqueous phase regulates the REE content in waters and the value of cerium and europium anomalies.","PeriodicalId":471278,"journal":{"name":"Вестник Московского университета","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135943757","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}

Organic matter changes during laboratory modeling of maturation, controlled by pyrolytic parameters, follow the same trends as in natural source rocks. The kinetic spectra of kerogen activation energy destruction show a heterogeneity of organic matter inside the rock. At the constant frequency factor, a decrease in low-energy bonds and an increase in the release of hydrocarbon compounds from 53 to 54 kcal/mol are observed. Calculated changes in hydrocarbon compounds formation at different activation energies depending on maturity level are different from experimental ones, which indicates the influence of maceral composition and necessity to take into account a variability of individual components in basin modeling.","PeriodicalId":471278,"journal":{"name":"Вестник Московского университета","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135943745","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}
