采用Rb Sr同位素定年方法 ,对新疆卡拉脚古牙锑金矿床赋矿地层的含炭泥质千枚岩进行测定 ,获得Rb Sr等时线年龄 379± 1 9Ma ;成矿时代采用主成矿期与锑金共生的石英 ,利用4 0 Ar- 39Ar法获得成矿时代为 1 1 8。
3.
Although the metallogenic age of this deposit is not known, studies show that it was formed in Caledonian, with the rock-forming age earlier than the ore-forming age.
在空间上,石居里辉长岩与石居里铜矿紧密相关,石居里辉长岩位于石居里铜矿的下部;在时间上,虽然目前尚无石居里铜矿的成矿时代年龄,但研究认为与石居里辉长岩同属加里东期,而且成岩时代早于成矿时代,因此推测石居里辉长岩为可能为石居里铜矿提供了热源。

通过对矿质来源、控矿构造、流体特征、成矿时代等控矿因素的分析 ,确定早期成矿作用为中高温热液蚀变岩型 ,矿体受北西西—东西向张性断裂控制 ,成矿年龄为 (2 39± 34 )Ma,与华力西晚期的岩浆活动有关 ;晚期成矿作用为中温热液充填脉型 ,矿体受北北西—北西向压扭性断裂控制 ,其成因与燕山期的岩浆活动有关。
