摘要
卡特里西铜锌矿位于塔里木陆块南缘晚古生代喀拉米兰弧沟系中,成矿与海相火山沉积作用有关,含矿地层为下石炭统托库孜达坂群基性凝灰岩层,矿体与基性凝灰岩层产出几乎一致,层控特征明显,一般呈层状、似层状、透镜状。以寻找海相火山沉积型矿床为目标,在矿区共圈出5条工业矿体,并经深部钻探,结果显示含矿层延深稳定,矿区资源储量规模有望达到中大型,深部找矿潜力突显。通过深入总结卡特里西铜锌矿的地质特征及找矿标志,为矿区下一步找矿及东昆仑地区同类型矿床的找矿工作提供参考。
The Katelixi copper-zinc deposit is located in the Late Paleozoic Karamiran arc-trench system of the southern margin of the Tarim block. Its mineralization is related to marine volcanic sedimentation. Its ore bearing stratum is the mafic tuff bed of the Lower Carboniferous Tuokuzidaban Group. Stratiform,stratiform-like and lenticular orebody and mafic tuff layers have roughly the same occurrence,which are obviously controlled by strata. With the deposit of marine volcanic sedimentary type as the searching target,5 industrial ore bodies were delineated in the mining area. Deep drilling reveals that the ore bearing stratum is deep and stable,and the resource reserves of the mining area is expected to be of medium and large size. This paper summarizes the geological characteristics and prospecting indicators of the Katelixi copper-zinc deposit,so as to provide guidance for prospecting in the next stage and for the same type of ore deposits in East Kunlun area.
