杨砦峪金矿床地质特征及深部成矿远景评价

Geological characteristics and evaluation of deep-seated mineralization prospect in Yangzhaiyu gold deposit,Henan Province

杨砦峪金矿床为河南灵宝小秦岭地区一重要大型石英脉型金矿床 ,矿床空间产出受太华群变质地层、岩浆岩及断裂构造控制 ,层间断裂为主要容矿构造。矿脉内矿体产出表现出“尖灭再现”、“尖灭侧现”规律。综合研究表明 ,小秦岭地区金矿床深部具有存在第二矿化富集段的可能性 ,在杨砦峪矿区 ,矿脉东段深部仍存在较好的成矿远景和找矿潜力。

Yangzhaiyu gold deposit is an important one in Xiaoqinling region,Henan Lingbao. Taihua group metamorphic suites,magmatic rock and fault tectonics control the spatial occurrences of the vein. Interlayer fault is themain ore-controlling structure. In the vein,deposit present features of thin out reappearing and side appearing. The synthetic study shows that the deep-seated gold deposits in Xiaoqinling area are probable to be the second mineralization enrichment area. In Yangzhaiyu mining area,there is great mineralization prospect zone and better exploration potentiality for the deep levels in the east of the vein.
