| 摘 要： | 超大型拖布卡金矿的发现,表明东川地区具备找金前景.“黑层”是金的成矿前提,断裂加蚀变是成矿必备条件,基性与中性岩脉在容矿层中的侵位,是找富金的重要标志.金成矿全过程应是多旋回（晋宁、华力西、燕山、喜马拉雅山）成矿作用,且受剪切破碎带控制的黑层型金矿.

| Abstract: | The discovery of large scale Tuobuka Au deposit shows the Au-prospecting potentiality in Dongchuan region. The prerequisite of Au metallogenesis is the "Black Bed"; the necessary conditions of Au metallogenesis are fault and alteration;the important marks of prospecting for rich Au deposit are the emplacements of basic and intermediate rock veins in the ore-bearing beds. Therefore, it belongs to the "Black Bed" type Au deposit formed by the polycyclic(Jinning, Variscan, Yanshanian, Himalayan) metallogenesis and controlled by the shear fracture zone. |
