东天山帕尔塔格西铜矿床地质特征及找矿方向

Geological Characteristics and Prospecting Direction of Paltagexi Copper Deposit of Eastern Tianshan

东天山帕尔塔格西铜矿是近年新疆地矿局继土屋铜矿之后在该矿带深化找矿认识中实现的又一重大突破。其处于东天山古生代造山带小热泉子石炭纪岛弧带,产于晚石炭世花岗闪长岩和闪长玢岩中,呈细脉浸染状矿化,与土屋铜矿特征类似,属斑岩型铜矿。通过初步勘查及资料分析研究,总结了矿床产出的地质环境、控矿要素、矿体特征、找矿标志,探讨了矿床成因,指出今后进一步扩大矿床规模及找矿方向。

After the discovery of Tuwu copper deposit,the paltagexi copper deposit is another major breakthrough in deepening the understanding of ore prospecting in this ore belt.It is located in the Carboniferous island arc belt of Xiao Re Quan Zi in the Paleozoic orogenic belt of East Tianshan,and occurs in the Late Carboniferous granodiorite and diorite porphyrite.It is a porphyry copper deposit with veinlet disseminated mineralization similar to Tuwu copper deposit.Based on preliminary exploration and data analysis,this paper summarizes the geological environment,ore controlling factors,ore body characteristics and prospecting criteria of the deposit,discusses the genesis of the deposit,and points out the prospecting direction for further expanding the scale of the deposit in the future.
