摘要
九丈沟金矿是豫西地区开发最为成功和效益最好的金矿床之一。矿区主要出露长城系熊耳群安山岩类。频繁活动的中新生代岩浆侵入和发育的断裂构造背景使其具有光明的找矿前景。金矿体主要受断裂蚀变带控制。硅化、黄铁矿化与金的关系最为密切。综合金矿石与矿区及区域主要岩石的稀土元素配分模式对比、Y-Ho关系和LREE/HREE-REE关系研究,认为岩浆侵入活动与成矿的关系最为密切。
Jiuzhanggou gold deposit is one of the most successful and profitable gold deposits in western Henan province. The mining area mainly exposed the Great Wall system xiong er group andesite. Because of frequent meso-Cenozoic magmatic intrusion and fault structure background, it has bright prospecting prospect. The gold orebody is mainly controlled by fault alteration zone. Silicification and pyritization are most closely related to gold. Based on the comparison of REE distribution patterns, Y-HO relationship and LREE/HREE-REE relationship between gold ore and main rocks in mining area and region, it is considered that magmatic intrusion is most closely related to mineralization.
