The polygenetic complex (G), magmato-metamorphic (Archaic-Proterozoic medium), with granitoids, gneiss, migmatite, xenolith is followed by a transition sequence (A) that appears to be an unevolved crust of alteration. Several genetic markers (quartz, potassic feldspar, triclinicity, myrmekites and perthites, restites, apatite and zircon) were identified. The three sedimentary units (B-C-D) considered the Lower Cryogenian age – medium. (Rifean, Geru, 1987) constitutes the beginning of the depositional sequence in the basin of the Dniester (with microconglomerate and coarse sandstones belonging to the Olcedaev member). The sequence reflects a shift from a LST regime to a transgressive TST regime, in which we have reconstituted sedimentation in shallow waters from the deltaic or coastal systems, with channel facies, levee and facies of the coastal or alluvial plains.","PeriodicalId":430014,"journal":{"name":"Bulletin of the Institute of Geology and Seismology","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121401825","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}

Statistical analysis of the main components indicated a high specialization of metal pollution in the industrial areas. Soil pollution in areas of children's institutions had a clear residential-transport character. The elimination of a multisectoral industrial production, the redevelopment of industrial areas and an increase in traffic intensity in the city over the past 30 years should have led to a significant change in the spatial structure and spectrum of pollution in the city of Chisinau.","PeriodicalId":430014,"journal":{"name":"Bulletin of the Institute of Geology and Seismology","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116672762","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}
