摘要/Abstract

摘要： 近年来，在西准噶尔北缘乌什加嘎衣提地区发现了布兰萨拉金铜矿床、乌什加嘎衣提金矿床和多处金、铜矿（化）点，找矿效果显著。为近一指导找矿工作，结合该区内已取得的地质研究成果，通过分析区域地质背景、矿化类型及矿化特征，并深入探讨了控矿因素、构造与成矿关系等，研究表明：①金成矿与中酸性岩体、构造关系密切，一般产于岩体外接触带中的石英脉中；②铜矿化广泛发育于构造裂隙和蚀变带中，主要赋矿层位为谢米斯台组地层；③区内成矿期主要分为两期：志留纪与火山热液和构造活动有关的铜成矿时期，晚石炭与中酸性岩浆侵入活动和构造活动有关的金、铜多金属成矿时期。

Abstract: In recent years,the prospecting achievements are remarkable.The goldcopper deposit of Bulansala city,the gold deposit of Wushijiagayiti,and various gold and copper deposits have been discovered in the Wushijiagayiti area on the northern edge of West Junggar.The rearch shows that:①The gold mineralization is closely related to the mediumacid rock mass and structure.It is generally produced in the quartz veins in the contact zone of the rock;②copper mineralization is widely developed in tectonic fractures and alteration zones.The main orebearing horizons;③The oreforming period in the area is mainly divided into two phases:one is the copper mineralization period related to the volcanic hydrothermal and tectonic activities of the Silurian; the other is the gold and copper polymetallic related to the intrusive activity and tectonic activities of the Late Carboniferous and the mediumacid magma mineralization period.

Key words: xiemisitai,formation,gold mine,metallogenic regularity,oresearching prospect
