ResumoThe Paleogene-Miocene oil shales studied in the paper were taken from the outcrops and ejecta of mud volcanoes in Shamakhi-Gobustan and Absheron regions. The geological age, mineralogy, and chemical composition of the samples were studied by analytical investigations. Minerals found oil shales were described in detail in the relevant categories. Some appropriate classifications were made in connection with the chemical composition of samples. The indices such as CIA, CIW, PIA, "RR = SiO2/Al2O3" - chemical weathering index, the diagrams like "(Al2O - K2O) – CaO – Na2O", "A-CN-K", and also reflecting mobility characteristics of elements, and estimates on large-ion lithophile elements were used to study the paleoweathering characteristics. Keywords: oil shale; geochemistry; mineral; paleoweathering.
