摘要:

谢坑金铜矿产于岗察岩体北接触带,矿体赋存于二叠系大关山群上岩组大理岩、砂板岩与中酸性岩体接触带部位,有3个含矿段,NW向断裂及NE向次级断裂为主要控岩、控矿构造,而NE向主断裂则是主要导矿构造,通过研究地质特征,初步认为矿床属矽卡岩型、热液型、构造蚀变岩型复合型金铜矿。

Abstract:

Xiekeng gold-copper mine is locate in the north contact zone of Gangcha rock body,rock host in the contact zone of marble,sand slate and medium acidity rock body that belong to Daguanshan Group upper petrofabric of Permian.There are three contain mineral segments,NW trending fault and NE trending secondary fault are the main fault that control rocks and minerals,but NE trending main fault is the main ore-transmitting structure.Through research geological characteristics,we initially think the deposit is a skarns,hydrothermal and tectonic altered rock type composite gold-copper mine.
