摘要
长条状耿马花岗岩岩基(株)内部及接触破碎带为成金构造三级张性、张扭性、压扭性断裂控矿,毒砂矿化为找矿标志,应为断层控制、期后热液型金矿。
The Au deposit forming structures are in the rock body and the contact fracture zone of Gengma long band-form granite batholite(stock).The ore control structures are the tension and tension-torsion faults.And the ore prospecting mark is the arsenopyrite metallogenesis.It must be the hydrothermal Au deposit controlled by fault.
