摘要
河南嵩县庙岭金矿位于华北陆块南缘外方山地区,矿床赋存于中元古界长城系熊耳群火山岩中断裂构造带内,属破碎蚀变岩型金矿。成矿热液蚀变矿物钾长石Ar-Ar法定年的年龄为(121.6±1.2)Ma,矿床形成与区域上早白垩世构造-岩浆-流体活动有关,为岩浆期后热液活动的产物。
Miaoling gold deposit in Henan Province is located in Waifangshan Mountain which belongs to the southern margin of North China block,it occurs in Xiong＇er Group faults zone of Proterozoic Changcheng System,broken altered rock type deposit.The Ar-Ar age of hydrothermal K-feldspar is 121.6±1.2Ma,Deposit formation and the region related to the Early Cretaceous magma-structure-fluid activities.
