陕西省潼关县潼峪-麻峪地区金矿地质特征及成矿因素分析

Analysis of Geological Characteristics and Metallogenic Factors of Gold Deposit in Tongyu-Mayyu Area,Tongguan County,Shaanxi Province

小秦岭地区是我国重要的金矿矿集区,已探明的黄金资源储量达数百吨。潼峪-麻峪地区金矿床位于小秦岭金矿田西段,大月坪—金罗斑复背斜折转端;矿体主要赋存在洞沟组和三关庙组地层中的深变质片麻岩系的控矿断裂构造带中,并严格受断裂构造带控制。矿体呈似层状、透镜状,矿体较连续,产状较稳定,矿体形态中等;工业类型为含金多金属硫化物石英脉型,规模中型。

The Xiaoqinling area is an important gold ore concentration area in China,with proven reserves of hundreds of tons of gold resources.The gold deposit in Tongyu-Mayyu area is located in the west section of Xiaoqinling gold field,at the turning end of Dayueping-Jinluoban anticline.The orebodies mainly occur in the ore-controlling fault structural belt of the deep metamorphic gneiss system in the Donggou and Sanguanmiao formations,and are strictly controlled by the fault structural belt.The orebody is stratified and lenticular,the orebody is continuous,the occurrence is stable,and the orebody shape is medium.The industrial type is quartz vein type containing gold polymetallic sulfide,and the scale is medium.
