祁漫塔格西段白干湖钨锡矿区巴什尔希花岗岩序列及构造环境

Magmatic Sequence and Tectonic Setting of Bashierxi Granite in W-Sn Deposit of Baiganhu Area,the Western Sector of Qimantage Mountains

摘要: 祁漫塔格西段白干湖钨锡矿区的巴什尔希花岗岩由二长花岗岩和钾长花岗岩组成,岩石序列由早到晚包括6个单元,其侵位时代约为458~432 Ma;构造环境判别显示巴什尔希花岗岩形成于后造山构造环境;通过讨论,认为阿尔金断裂南侧的奥陶纪—早志留世偏铝质—过铝质A₂(PA)型花岗岩区是钨锡矿的重点找矿靶区。

Abstract: Bashenerxi granites of the western sector of Qimantage mountains consist of two rock types of adamellite and moyite,magmatic sequence includes sixunits from early to late,its age is about 458-432 Ma; tectonic discrimination shows Bashenerxi granites formed in the post-orogenic tectonic setting; through discussions that Ordovician-early Silurian A₂ (PA)-type granite of metaluminous-peraluminous in the south side of Altun fault is the focus of the exploration target of W-Sn deposit in.
