摘要
西天山吐拉苏地区晚古生代浅成低温热液金矿,明显受三个级别构造的渐序控制:近东西向吐拉苏构造火山岩盆地控制着金矿带;横跨盆地的近南北向构造火山岩带控制着金矿田;火山机构控制了金矿床的分布。
The Late Paleozoic epitherrnal gold deposits have been discovered in Tulasu area in west Tianshan mountains recently and were devided into two types : adularia-sericite type and silicified rock type,both are the active products of volcanic geotherml -fluid system and were controlled by three-grade structuresobviously in order: the Tulasu basin trending nearly E-W control, the regional metallogenic zone; the nearly NS structural belt crosscutting the nearly E-W one control the gold ore field; the volcanic apparatus control the distribution of gold -ore bodies. And the host structures of ore bodies are low-grade faults.
