摘要
老柞山金矿床的热液成矿作用可分为早、晚两期、7个成矿阶段。通过对各成矿期不同成矿阶段的矿体赋存特征、矿石类型、共生矿物组合、铷锶同位素年龄及铅同位素特征等方面研究表明 ,早期成矿作用与晚海西期构造岩浆活动有关 ,成矿时代为 (2 39± 34 ) Ma,而晚期成矿作用则与燕山期构造岩浆活动有关 ,成矿时代略晚于 12 3～ 146
The hydrothermal metallogenesis of Laozuoshan gold deposit is divided into two periods and seven stages.Based on the studies of the characteristics of orebody's occurence,ore type,coexisting minerals,Rb Sr and Pb isotopic age,etc,the early metallogenesis is related to Hercynian tectonomagmatic activities and its metallogenetic age is (239±34)Ma,but the late metallogenesis to the Yanshan tectonomagmatic activities and its metallogenetic age is slightly younger than 123～146Ma.
