摘要
绿沙金矿位于南秦岭褶皱带,合作—鹿儿坝—崖湾金、汞、锑等多金属成矿带上,处于鹿儿坝金矿西北部11 km处。矿区内圈定以Au为主的土壤综合异常4处,异常走向NW向为主,与区域地层展布及构造线方向一致;通过对AT3异常检查圈出金矿体3条,矿体赋存于中三叠统古浪堤组地层中,严格受断裂构造带控制,矿体走向以NW向为主,矿石具较强的褐铁矿化、硅化。本文在对矿区地质及矿体特征客观认识的基础上,分析总结了矿区的控矿因素和找矿标志,并与邻区的鹿儿坝金矿进行了对比。为该区及成矿带找矿工作具有借鉴意义。
Lvsha gold deposit is located 11 km northwest of Luerba gold deposit in the ore belt metallogenic belt of double entry, the deer DAM, Mercury bay, mercury, antimony, etc. In the mining area, the 1： 10000 soil survey is dominated by gold, and the anomaly is mainly Nishimukai, consistent with the regional stratigraphy and structure; Through the three anomaly detection ring withdraw ore body three, the ore body is hosted in the middle Triassic Gulangdi Formation, strictly controlled by fault structure, and mainly north of the ore body, the ore body is strong brown iron and silicification. Based on the objective understanding of the geological and ore characteristics of the mining area, the ore-controlling factors and prospecting criteria of the mining area are analyzed and compared with the Luerba gold deposit in the adjacent area.
