| 中文摘要: |
| 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(239±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123～146Ma |
| 英文摘要: |
| 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. |
