| 摘 要： | 研究区位于西南天山科克布克三山晚古生代铅锌铜金铁钒钛五级成矿带,成矿地质条件优越。20世纪90年代以来,发现一些找矿线索,但在研究区未能取得找矿突破。为解决该区的找矿问题,通过系统地开展1∶50000水系沉积物测量工作,圈定了一批化探综合异常,优选Hs46 乙_2综合异常为铅锌找矿靶区,采用激电中梯测量、激电测深工作确定了隐伏的矿化体分布和埋深,最终通过钻探验证发现了琼恰特北铅锌矿床,取得良好的找矿效果。

| Abstract: | The work area lies in the Cu-Ni-Au-Fe-Ti-V-Pb-Zn-RM-REE- vermiculite metallogenic belt in the northern margin uplift of Tarim, southwest Tianshan Mountains, where geological conditions of mineralization are good. Since the 1990s, some clues of ore search have been found here, but no breakthrough was achieved in this area. To solve this problem, The a stream sediment survey on a scale 1: 50000 has been carried out and a batch of geophysical and geochemical anomalies have been delineated, from which Hs46B2 was chosen as the target. Using IP intermediate gradient measurement and IP sounding, distribution and burial depth of polarized bodies have been determined. By drilling verification, finally a new type of lead-zinc deposits in northern Qiongqiate has been found, indicative of good application results. |
