Abstract:

查干德尔斯钼矿床是近年来在内蒙古西部中蒙边境地区新发现的一个具大型规模的隐伏矿床,辉钼矿化呈浸染状、团块状、细脉状分布在中细粒二长花岗岩中,具斑岩型矿床的特点。笔者在矿区成矿岩体、矿化和蚀变特征等初步研究的基础上,进行了辉钼矿Re-Os测年,获得模式年龄为(240.3±3.9)~(244.2±3.5)Ma,等时线年龄为(243.0±2.2)Ma〔MSWD=0.78,187Os初始值为(-0.3±2.4)〕,表明区内的钼成矿时代为三叠纪,属印支期构造-岩浆活动的产物。笔者经研究认为,内蒙古西部中蒙边境地区的额济纳旗—乌拉特后旗—苏尼特左旗一线为一钼多金属成矿带,并初步总结了该成矿带内成矿岩体和钼矿床的特征及找矿标志。
