Abstract

The sedimentary complexes of the Dombarovsk deposits (Ural eastern slope) underwent important transformation. The diagenetic rock alteration and the organic matter metamorphism observed in the Lower Carboniferous rocks are assumably due to frequent high tectonic stresses of various directions. Coals were transformed into anthracites of high degree of metamorphism, with a graphite-like structure in most altered parts. Intensive P-T stresses also transformed the minerals. The host rock minerals became structurally altered as to yield the 2M micas typical of high-temperature.
