Abstract

The black shale complex, which is organic carbon-bearing and characterized by syngenetic, epigenetic sulphidation and intense metamorphism in the Duruja structural-forma- tion zone of the southern slope of the Greater Caucasus, is the focus of geologists’ attention due to the mineralization areas, which are rich in significant non-ferrous, noble, radioactive metals, rare and rare earth elements. In order to determine the prospects of noble, non-ferrous, radioactive metals, rare and rare earth elements of the black shale of the Aghlig-Filfilli mineralization area of the Duruja zone, it is necessary to determine the mineralogical composition of the ores of the area, to study the textural-structural characteristics and to clarify whether the rocks of the zone are a source of complex ore raw materials. The object of the work is the mineragraphic and petrographic study of the numerous samples col- lected from the Aghlig-Filfilli mineralization area during the field expedition before the PhD admission period, during my post-graduate studies and currently in order to solve various important mineralogical and petrographic problems. In order to investigate the textural-structural characteristics and mineral types of the ores of the Aghlig-Filfilli mineralization area, thin sections and polished sections made from the samples were studied with the help of «Carl Zeiss» and «Polam-312» microscopes in transmitted and reflected rays. The composition, surface area and morphological characteristics of the monomineral samples were studied by the electron microscope «SEM». Accurate diagnosis of some minerals was carried out based on the results of their X-ray diffractometric analysis. According to the results of the research, the ores of the Aghlig-Filfilli mineralization area were formed in 3 stages: syngenetic, epigenetic and rem- ineralization as a result of strong metamorphism of syngenetic formations. At the same time, the origin of the ores of the Aghlıg-Filfilli mineralization area was studied. According to the results of the research, it was determined that epigenetic mineralization in contact with Aralig and Zangi deep faults in the north and south of the Aghlig-Filfilli area is of magmatogene origin (δ34S=1.6-4.6), and synge- netic mineralization in the black shales towards the center is of biogenic origin (δ34S= -18 – -22.6).
