康定金矿田主要分布在前震旦系康定杂岩中。康定大渡河两岸的结晶基底杂岩体,东、西、北界均为滑脱型剪切带所围限,结晶基底与盖层间强烈的剪切作用,使周缘上覆古生界地层大量缺失。在南北长60km、东西宽几千米至30 km范围内,金矿床(点)星罗棋布,构成了著名的康定大渡河“金谷”该矿区金矿主要形成于喜马拉雅期地壳的伸展过程(陈智梁等,1997;骆耀南等,1998;喻安光等,1998)。主要成矿年代为
The Kangding gold ore field is mainly distributed in the former Sinian Kangding complex. The crystalline basement complexes on both sides of the Dadu River, Kangding, are surrounded by slipping off shear zones in the east, west and north boundaries. The strong shear between the crystalline basement and the capillaries causes a large loss of the epicontinental Paleozoic strata . The gold deposits (dots) are dotted with 60km long and 60km wide from east to west and form the famous Kangding Dadu River. “Golden Valley” The gold deposits in the mine mainly formed during the extension of the Himalayan crust (Chen Zhiliang Et al., 1997; Luo Yaonan et al., 1998; Yu et al., 1998). The main mineralization age is
