GEOCHEMISTRY OF PRE-MESOZOIC GOLDBEARING FORMATIONS IN SHAOXINGLONGQUAN UPLIFT REGION, ZHEJIANG PROVINCE

【摘要】 <正> The geochemistry of the main country rocks of gold deposits in Shaoxing-Longquan uplift region has been systematically studied in this paper. The authors believe that the Proternzoic Shuangxiwu group is the primary gold-bearing formation in this region and the Sinian-Cambrian Chencai group and the Precambrian Zuoxi migmatized quartz-diorite are the derivative gold-bearing formations. The genesis of rocks, content distribution features of gold and silver, characteristics of associated trace elements and other geochemical features in these formations clearly show a relationship of inheritance with evolution. By means of metamorphic-solution and volcanic-solution or/and other geological actions, these gold-bearing formations supplied the necessary ore-forming materials for the gold deposits in this region.更多还原
