Geological journal| Zusammenfassung: | This study presents the results of a detailed investigation of Upper Jurassic carbonate-terrigenous deposits within the Side Range structural formation zone of the Southeastern Caucasus. The research involved stratigraphic profiling, spatial correlation of sections, and systematic mineralogical and geochemical analysis sampling. The deposits primarily consist of fine- to medium-grained sandstones, pelitic and microcrystalline limestones, argillites, and fine-grained conglomerates, indicating accumulation on a steep continental slope. Geochemical data show a consistent composition across stratigraphic levels, suggesting moderate sediment maturity and a predominantly mechanical origin. Based on the petrochemical parameters studied, the Upper Jurassic rocks have been classified as lithogenic formations, which do not contain volcanic or terrigenous-pyroclastic impurities. They are categorized as normal siallites and pseudosiallites. |
