新疆且末县屈库勒克一带金铜矿找矿远景研究

Research on the prospecting prospect of gold and copper deposits in the Qukuleke area of Jimo County,Xinjiang

研究区属于阿尔金南缘金、铜、镍、铁、钨成矿区喀拉米兰金、铜及多金属成矿带的重要组成部分,研究表明:①屈库勒克东金矿(I号矿体)向东延伸仍然具有较好的找矿潜力;②布拉克巴什代牙东金矿(II号矿体)与I号矿体成因类型不同,属构造带内多期热液活动之岩浆后期沿裂隙贯入的含矿热液成矿,规模不大;③屈库勒克-洒阳沟构造带内的矿化类型均与目前所发现的矿体一致,是今后找矿突破的最有利地段;④穷乃克纳克铜矿找矿远景区受构造控制明显,与西部卡特里西中型铜锌矿处于同一构造部位,沿矿体东、西两侧的构造蚀变带还是有一定的找矿前景;⑤且末县屈库勒克金锑找矿远景区主矿体深部已由钻孔完全控制,深部元素原生晕特征显示,与浅部元素相比,个别剖面As、Au等前缘元素浓度值相对较高,说明个别地段深部存在盲矿体的可能。

The study area belongs to the gold,copper,nickel,iron and tungsten metallogenic area of the southern margin of Altyn,and the karamian gold,As an important part of the copper and polymetallic metallogenic belt,the results show that:①the eastward extension of the Kukulek East Gold Deposit(No.1 ore body)still has good prospecting potential;②the Bulakbashdaiya East Gold Mine(No.2 ore body)is different from the No.1 ore body,and belongs to the ore-bearing hydrothermal mineralization along the fracture in the later stage of magma with multi-stage hydrothermal activity in the tectonic belt,and the scale is not large;③The mineralization types in the Kukulek-Sayanggou structural belt are consistent with the ore bodies found so far,which is the most favorable location for prospecting breakthroughs in the future;④The prospecting prospect of the Kuknaiknak copper mine is obviously controlled by the structure,and is in the same structural part as the medium-sized copper-zinc ore in Katrisi in the west,along the east of the ore body⑤The deep part of the main ore body in the Qukulek gold-antimony prospecting prospect area in Moxian County has been completely controlled by the borehole,and the primary halo characteristics of the deep elements show that compared with the shallow elements,the concentration of leading elements such as As and Au in individual sections is relatively high,indicating that there is a possibility of blind ore body in the deep part of individual sections.
