摘要
Langda Cu deposit,which is part of Gonggar-Gaca east-west Cu polymetallic metallogenic belt and originates in fractured zone of middle acidic magmatic rock in Himalaya Period,is located at the north of arc-land collision suture zone of Yarlung Zangbo River and on the southern margin of Gangdise epicontinental magmatic-volcanic arc.Two mineralization belts in vein,lenticular and layered shapes that discovered so far are controlled by near EW or NWW fractures in this mining area.Most ore structures are in banded,veined and brecciated shapes,while part of the polymers are in ataxitic or disseminated shapes.According to the careful analysis on geologic conditions,ore bodies and ore features of the mining area,structure and magmatic hydrothermal fluid are the major controlling factors.In conclusion,this area has favorable prospecting potential.
