| 摘 要： | 藏南冲木达铜矿床属矽卡岩型铜矿床。矿区出露地层为上侏罗统—下白垩统桑日群比马组,遭受不同程度的矽卡岩化蚀变或区域浅变质作用。矿区铜矿(化)体主要赋存于比马组3~4段透辉石榴矽卡岩、矽卡岩化大理岩中,并主要产出于断裂构造带及其断裂两侧附近。铜矿(化)的形成经历了矽卡岩化阶段和热液硫化物阶段。

| Abstract: | The Chongmuda copper deposit in Sangri,southern Xizang is considered as skarn-type copper deposit,and was hosted in the Bima Formation of the Upper Jurassic-Lower Cretaceous Sangri Group which has been subjected to the skarnization and regional epimetamorphism.The copper orebodies(mineralized orebodies) in the deposit mostly occur in diopside garnet skarn and skarnized marble in the third to fourth members of the Bima Formation along or around the fractured zones.The formation(mineralization) of the copper deposit is involved in two phases of skarnization and formation of the hydrothermal sulfides. |
