摘　　要：新平县石门坎金矿矿体呈似层状、透镜状产于花岗闪长斑岩岩脉两侧接触带及岩层之层间破碎带中,矿体围岩为花岗闪长斑岩和泥盆系上统(D3)碎屑岩,矿体产状分别与岩体接触带产状和岩层产状基本一致。岩体接触带、层间断层破碎带以及硅化、黄铁矿化、毒砂矿化、辉锑矿化是重要的找矿标志,矿床类型属热液型金矿床。The orebody of Shimnkan in Xinping is stratoid,lenticular in the contact on both sides of granodiorite porphyry and the interlayer fracture zone.The wall rock of orebody is the granodiorite porphyry and Upper D(D3)clastic rock.The occurrence of orebody consists basically to that of rock body contact and rock bed separately.The rock body contact,interlayer fracture zoe,signification,pyritization,arsenopyritization,stibntization are the important prospecting criteria.I is a hydrothermal Au deposit.
