Abstract

Au-Ag-Te-Se-bearing epithermal mineralization at Prasolovskoye occurs along fault zones developed within a circular intrusive zone in Miocene to Quaternary age volcanic rocks. The ores show complex textures and mineralogy and can be divided into three stages based on tectonic fracturing and mineral associations: pyrite (I), polymetallic (II), and gold-silver (III). Stages I and II occur as hydrothermal replacement zones, veins, and breccias and are base metal sulfide rich without economic gold and silver grades. Following intrusion of rhyolitic dikes after stages I and II, gold-silver mineralization (stage III) formed during the late Pliocene. Vein-related, wall-rock alteration zones occur along stage III veins, overprinting pervasive propylitic assemblages, and consist mainly of silicification and sericitization. Stage III ore mineralization is composed of four substages which show a progressive change in mineralogy with increasing paragenetic time. -from Authors
