云南勐腊县龙巴河铜矿特征及找矿标志
|
摘要
龙巴河铜区位于位于扬子准地台西缘兰坪-思茅中生代塌陷南部。矿体呈层状或似层状沿近东西向断层破碎带展布,矿体围岩为中侏罗系统小红桥组上段(J_2x~2),含矿岩性主要为泥质粉砂岩、石英细砂岩,矿体明显受断层构造及地层控制。其矿床成因类型为地下热水溶滤铜矿床,矿区深部及外围有较大找矿前景。
Longbahe Cu orefield is in the S part of Lanping-Simao Mesozoic depression of W margin of Yangzi paraplatform. The ore body is bedded or stratoid,distributed along nearly EW fault fracture zone. The wall rock of ore body is Middle Jurassic Xiaohongqiao Formation Upper Member( J_2 x~2),the main ore-bearing rock is muddy siltstone,quartz fine sandstone. The ore body is controlled clear by fault and strata. It is a Cu deposit of underground hot water solution-filter in genesis. There is good prospecting potentiality in the deep and surrounding area..
