摘要
红柳沟基性-超基性岩体是笔者开展1∶5万矿产地质调查期间新发现和厘定的含铜镍矿化岩体,它位于塔里木板块北缘北山裂谷带,夹持于大山头-岗流脑子和方山口-庙庙井-双鹰山断裂带之间,北西距黑山大型铜镍矿床约30 km,是一个非常重要的铜镍成矿区。运用地物化遥等综合找矿技术方法,在充分系统研究地质背景的前提下,利用1∶5万水系沉积物和磁法测量对空白区进行扫面,圈定异常,进而开展大比例尺地质测量和激电中梯及激电剖面测量工作,进一步圈定出成矿区内若干有利的成矿地段,择优开展槽探和钻探工程验证,新发现红柳沟Ⅲ、Ⅳ号铜镍矿点,取得了较好的找矿效果,说明综合运用物化探找矿方法是可行、有效的,对进一步指导该区及区域上的铜镍找矿工作具有借鉴意义。
Hongliugou basic-ultrabasic rock mass is a copper-nickel mineralized rock mass newly discovered and determined during the author's 1∶50000 mineral geological survey.It is located in the Beishan Rift zone on the northern margin of Tarim Plate,sandwiched Dashantou-Gangliuxin and Fangshankou-Miaomiaojing-Shuangyingshan fault zone,and is about 30 km to the northwest from Heishan large copper-nickel deposit.Under the premise of fully and systematically studying the geological background,comprehensive prospecting techniques such as geological,physical,chemical and remote prospecting are used to sweep the blank area with 1∶50000 drainage sediment and magnetic survey to delineate anomalies,and then large-scale geological survey and exciting elevator profile survey are carried out to further delineate some favorable ore-forming areas in the metallogenic area.The channel exploration and drilling engineering verification are carried out in an optimal manner,and the Cu-Ni ore spots No.Ⅲand IV in Hongliugou are newly discovered,and better prospecting results have been obtained,which indicates that the comprehensive application of physicochemical prospecting method is feasible and effective,and has reference significance for further guiding the Cu-Ni prospecting work in this area and the region.
