云南香格里拉市红山铜矿特征及找矿标志

THE FEATURE AND PROSPECTING CRITERIA OF HONGSHAN CU DEPOSIT IN XIANGGELILA,YUNNAN

云南香格里拉红山铜矿,矿体呈似层状、透镜状赋存于,印支期中酸性岩浆侵入岩体与三叠系上统曲嘎寺组接触带外带的矽卡岩、角岩和大理岩层中,矿体产状与岩层产状大致相同,呈顺层产出。该铜矿的形成与印支期中酸性岩浆侵入活动有关,属复成份热液矽卡岩型铜矿床。中酸性岩体侵入接触带及矽卡岩化是重要的找矿标志。

The orebody of Hongshan Cu deposit in Xianggelila,Yunnan is stratoid,lenticular in the skarn,hornfels and marble in outer contact between Indosinian intermediate-acid magmatic intrusion body and Upper Triassic Qugasi Formation.The occurrence of bedding orebody is as same as that of the rock bed in the rough.The metallogenesis is related to Indosinian intermediate-acid magmatic intrusion,belonging to the composite hydrothermal skarn Cu deposit.The important prospecting criteria are the contact of intermediate-acid intrusion body and skarnization.
