河南省西峡县高庄金矿床地质特征及找矿前景

朱阳关-夏关断裂是一条长大于400km,深达上地幔的超壳断裂,沿断裂出露有较多的燕山期花岗岩（脉）体及一系列Cu、Au、Ag、Pb、Zn异常,有色金属、贵金属成矿作用明显。高庄金矿床赋存在朱阳关-夏关断裂次级断裂带中,为海底火山喷流-岩浆-构造热液叠加改造形成的含金石英脉-蚀变构造岩型金矿。本文分析了高庄金矿床特征,找矿标志。提出了在朱阳关-夏关断裂带中寻找金多金属矿床潜力较大。随着深部地质找矿的进一步开展,本区可成为我国重要的金多金属矿产基地。

Geological characteristics and prospect for prospecting work of Gaozhuang gold deposit in Xixia,Henan

Zhuyangguan-Xiaguan faulted zone is a more than 400 km ultra-shell faulted zone deep to upper mantle,there are more exposed granites（veins） of Yanshanian stage and a series of abnormal Cu,Au,Ag,Pb and Zn along the faulted zone,and there is also obvious metallogenesis of non-ferrous metal and precious metal.Gaozhuang gold deposit existing in the secondary faulted belt of Zhuyangguan-Xiaguan faulted zone is an auriferous quartz vein-alteration structural rock type gold ore formed by superimposing submarine volcano jet flow-magmatic hydrotherm-structural hydrotherm.This paper analyzes the characteristics of Gaozhuang gold deposit and markers for prospecting work,and also suggests the greater potential to seek polymetallic gold deposits in Zhuyangguan-Xiaguan faulted zone.Along with the further development of deep geological prospecting work,this zone may become an important polymetallic gold base of China.
