Some features of formation of hydrothermally altered rocks of volcanogenic areas (propylites, secondary quartzites) and their prospecting significance

Abstract
The wide development of geological research in volcanogenic areas contributed to the discovery of a number of deposits and ore occurrences of metals (Au, Ag, Si, Mo, Pb, Zn, Sb, Hg, Bi, U, etc.) and nonmetals (alunite, corundum, sulfur). In turn, these discoveries attracted the attention of geologists to the elucidation of ore-bearing volcanogenic formations in general and to the study of the peculiarities of formation of hydrothermally altered rocks with which the ore occurrences are associated, in particular ...
