| 摘 要： | 新疆伽师铜矿床产于新生界古近系苏维依组中,通过对新疆伽师铜矿床地质特征、赋矿的苏维依组岩石化学、微量元素和稀土元素地球化学特征研究表明,伽师铜矿区富集Pb、Cu、Ag、As元素,具有较好的铜成矿背景;赋矿的古近系苏维依组的物源区构造环境为活动大陆边缘;Cu元素主要来自于上白垩统巴什基奇克组的风化产物;铜矿床的形成明显受地层、岩性、古气候环境和构造的控制,属古近系潟湖相沉积作用和构造富集作用有关的砂岩型沉积-构造富集型铜矿床。

| Abstract: | Jiashi Cu deposit occurs in Suweiyi formation of Cenozoic Palaeogene System. The geological characteristics of the deposit and research on geochemistry, trace element and REE geochemistry of the host rock of Suweiyi formation show that the surrounding area of the deposit is riched in Pb, Cu, Ag, As with potential for Cu ore prospecting. Source area of Suweiyi formation is active continental margin. Cu comes mainly from the weathered material of Upper Cretaceous Bashijiqike formation. The Cu deposit is apparently controlled by stratum, lithology, palaeo-climate and tectonics. It is a sandstone-hosted sedimentary-tectonic ore material enriched Cu deposit related to lagoon sedimentation. |
