摘要:
五龙沟金矿床是东昆仑成矿带内典型的金矿床,该矿床主要受三条NW-SE向的大型韧性剪切带控制,矿体集中赋存于14条次级含金破碎蚀变带中。通过对五龙沟金矿床地质特征、控矿构造、矿体富集规律、富集标高的研究,认为矿区内韧性构造控矿则矿体长轴与运动方向一致,而脆性断裂控矿则矿体长轴与运动方向垂直。据此提出了新的预测区,经工程验证,取得了显著的效果。表明五龙沟金矿深部和外围仍具有较大的找矿潜力,为下一步找矿指明了方向。
Abstract:
Wulonggou gold deposit is one of the typical gold deposit in the east Kunlun metallogenic belt. The deposit is mainly controlled by three major NW-SE trending ductile shear belts, and concentrated gold ore body occur in the fourteen secondary gold-bearing fractured alteration zone. Based on the study of the ore deposit geo-logic features, ore-controlling structure, the enrichment regularity of the ore body, enrichment of elevation, we conclude that under the control of ductile structure, the orebodies in long axis and the movement are in the same direction, and which are in the vertical direction are controlled by the brittle fracture. Meanwhile, we proposed the new predicting area, which was verified by engineering, has obtained the remarkable result. It show that Wulong-gou gold deposit still has the great deep and periphery prospecting potential, which point out the direction for the further prospecting.
