摘要/Abstract

摘要：

拉水峡铜镍矿位于秦祁昆造山系西南缘日月山—化隆新元古代地块中部。赋矿地层为化隆岩群的一套中高级变质岩系, 岩性主要为黑云斜长片麻岩、角闪片岩。因矿区普遍被厚50～150 m 的古近系—新近系西宁群紫红色砂砾岩、粘土岩等岩层覆盖, 采用常规的矿产勘查方法很难发挥作用。近几年在该矿区通过1∶5 000地气汞气测量详查工作, 共圈出地气汞气异常11处, 初步认为Ⅰ号和Ⅲ号异常找矿意义最大。结果表明利用地气汞气测量方法对寻找隐伏矿床有一定借鉴意义。

Abstract:

Lashuix ia Cu-Ni deposit is located in the middle of Riyue Mountain-Hualong new proterozoic mass if which is the southw estern margin of Qin-Qi-Kun orogenic belt.Host stratum is a set of intermediate and advanced level metamorphic rock of Hualong group, which mainly included biotite plagioclase gneiss and horn blendic schist.Because the mining field is covered by strata, about 50～150 m thickness, purplishred conglomerate and clay rock and so on in paleogene-neogene Xining group. In this area, it is difficult to play a role by using conventional mineral exploration method. Eleven anomalies have been found in this mining area recently by 1∶5 000 geogas and mercury gasmeasurement detailed investigation. Preliminary,Ⅰ anomaly and Ⅲ anomaly have a great prospecting significance. These results show that geogas and mercury gas measurement has a certain referential significance for finding concealed ore-beds.

Key words: Geogas and mercury gas measuremen, Concealed orebody, Anomaly characteristics, Lashuixia Cu-Ni mining area
