Geology
The geological structure of the mountain is highly complex. Its western section consists of a granite-diorite intrusion and Upper Proterozoic phyllite and quartzite formations, with thicknesses ranging from 500 to 3000 meters. The central part is primarily composed of Lower Paleozoic granites and granite-diorites. The eastern section is formed of Ordovician sedimentary rocks, including sandstones, tuffs, porphyrites, limestones, conglomerates, and other deposits, with thicknesses between 1000 and 4600 meters.In the intermontane depressions, Neogene and Quaternary sedimentary deposits are present. The mountain range contains nepheline syenite massifs, which are associated with aluminum ore deposits.
