位于武夷隆起带西坡的江西熊家山钼矿床具有独特的矿化特点。本文概要地介绍了该钼矿的矿床地质特征,通过对辉钼矿的Re-Os同位素组成的测试分析,获得模式年龄151.7~161.6Ma,并计算出等时线年龄为152±20Ma,钼矿成矿作用发生于燕山早期。通过与我国大量的与岩浆作用有关的铜铅锌银多金属矿床辉钼矿Re含量的对比分析,揭示出熊家山钼矿成矿物质来源于上地壳,成矿构造背景归属于武夷隆起成矿带而不是赣东北构造成矿带。
The Xiongjiashan molybdenum deposit located in the west slope of Wuyi uplift belt has unique mineralization characteristics. This paper presents an overview of the geological characteristics of the molybdenum deposit. Through the analysis of the Re-Os isotopic composition of the molybdenite, the model age is 151.7-161.6 Ma and the isochron age is 152 ± 20 Ma. The molybdenum deposit Mineralization occurred in the early Yanshan. By comparing and analyzing the Re content of molybdenite with a large number of magmatic copper-lead-zinc-silver polymetallic deposits in China, it is revealed that the ore-forming materials of the Xiongjiashan molybdenum come from the upper crust and the metallogenetic structure belongs to the Wuyilong uplift mineralization Instead of tectonic belt in northeastern Jiangxi Province.
