摘要
三眼井铜矿属于沉积再造层控型砂岩铜矿,赋存于上泥盆统沙流水群紫红色砂砾岩的不完全退色层及断层破碎带中,呈似层状、透镜状、脉状,主要受褶皱或构造破碎蚀变岩带控制.结合三眼井铜矿的地质特征,分析其找矿标志,以更好地开发砂岩型铜矿资源.
Abstract
The Sanyanjing copper deposit belongs to the sedimentary regeneration strata-controlled sandstone copper depos-it,which occurs in the incomplete recession-colored layer and fault fracture zone of the Upper Devonian Shailiu Group.It is stratified,lenticular and vein-like,and is mainly controlled by the fold or tectonic fracture alteration zone.Based on the ge-ological characteristics of Sanyanjing copper mine,analyzes its prospecting signs in order to better develop sandstone copper resources.
