摘要
八卦庙金矿是产于秦岭泥盆系地层中的超大型金矿床 ,对成矿地质背景、矿床地质特征综合研究表明 :晚泥盆世的热水沉积作用形成初始层状矿体或矿源层 ;海西—印支期的脆-韧性剪切作用控制着金的成矿过程并形成金矿体的主体 ;燕山期的岩浆气液对金矿的再次叠加富集最终形成金矿床。因而具有多期次复合成因特点。
Occurred in the Devonian system in Qin Mountain,Baguamiao Gold Deposit is a super large one.From comprehensive study of geologic background of mineralization and geologic characteristics of deposit,it shows that the thermal water sedimentation in late Devonian epoch resulted in initial layered orebody or ore source layer;the brittle tough shearing of Haixi Indo chinese epoch controlled the process of gold mineralization and formed the main part of gold orebody;the magmatic gas or solution of Yanshan epoch superimposed or reconcentrated on the ores and finally resulted in gold deposit,so it provided the characteristic of complex origin of multiple phase.
