Characteristics and Prospecting Potential of Quartz Vein-Type Gold Deposits in Saishiteng Area, Qinghai Province

Saishiteng gold deposit, located in Leihu Town of Qinghai Province, is a composite endogenetic quartz vein-type gold deposit.Mineralization occurs in Caledonian quartz veins and the contact and shear alteration zones, characterized by intensively developed quartz veins, concentrated mineralization, high gold content and good nesting of drainage anomalous. Though gold deposits of Tanjianshan altered-type, Yeluotuoquan tectonic altered-type, Hongliugou quartz vein-type and Saishiteng composite endogenetic quartz vein-type were in the same tectonic unit (Northern margin Junction of the Qaidam basin) and the same metallogenic sub-belt (the Saishiteng-Alto Mountains metallogenic sub-belt), different types of gold deposits were formed in different ore-forming ages and positions.The comparison of different gold deposits is of practical guiding significance for metallogenic regularities and further comprehensive prospecting.
