河南小秦岭北矿带深部金(钼)矿床地质特征及潜力分析——来自F5深部探矿的启示

河南省小秦岭金矿田北矿带在全国地质找矿战略突破行动中新增金金属量25500 kg,新增钼金属量85714 t,取得了较好的找矿成果。本文在收集研究小秦岭北矿带以往地质勘查、开采及科研资料基础上,总结了小秦岭北矿带矿床地质特征,矿石类型由石英脉型为主渐变为构造蚀变岩型为主。通过分析小秦岭北矿带最新普查成果,综合本区以往找矿预测研究,揭示了小秦岭北矿带深部尚有很大的找矿空间。印证了"一街五巷三层楼"预测找矿模型在小秦岭深部找矿中的意义,对小秦岭其他矿带开展深部普查,实现整个小秦岭地区深部找矿的突破具有参考价值。

Geological characteristics and prospecting potential of deep gold (molybdenum) deposits in North Xiaoqinling ore belt, Henan Province:Inspiration from F5 deep exploration

The north ore belt of Xiaoqinling gold mine in Henan Province added 25500 kg of gold and 85714 t of molybdenum in the breakthrough of national geological prospecting strategy,and achieved good prospecting results. In order to provide confidence,experience and technical reference for other Xiaoqinling ore-prospecting breakthroughs,on the basis of collecting and studying the previous geological exploration,mining and scientific research data of Xiaoqinling Northern ore-belt,this paper summarizes that the deposits in Xiaoqinling Northern ore-belt have increased from shallow to deep,and the scale of the main ore-bearing structural belt has increased. The main ore type is quartz vein type,and the main one is tectonic altered rock type. Through the analysis of the latest survey results and the synthesis of previous prospecting and prediction studies in this area,it is revealed that there is still a great space for prospecting in the deep part of Xiaoqinling Northern ore belt. It verifies the guiding significance of the"one street,five lanes and three floors"prediction prospecting model in the deep prospecting of Xiaoqinling,which is of certain reference value to carry out the deep prospecting in other ore belts of Xiaoqinling and realize the breakthrough of the deep prospecting in the whole Xiaoqinling area.
