河南省新县姚冲钼矿床地质特征及控矿因素

摘要

Yaochong molybdenum deposit was a newly discovered conceal mineral deposit in Xinxian County, Henan Province. It is located in the Dabie Mo-polymetal metallogenic belt . Based on analysis and research on regional geological setting and its geological characteristics it is considered as a porphyry molybdenum deposit. Ore bodies occur in Dabie gneissic complex and Mo mineralization is closely related to conceal granitic porphyry and structure. Discovery of the deposit is practically significant to guide exploration of conceal ore deposit in the molybdenum metallogenic belt of Dabie Mountain.%河南省新县姚冲钼矿床是近年来新发现的隐伏矿床,矿区位于大别山北麓钼多金属成矿带.通过对区域地质背景及矿区地质、矿床地质特征等方面的分析与研究,认为姚冲钼矿属斑岩型矿床,矿体主要赋存于大别片麻杂岩中,钼矿化与隐伏花岗斑岩和构造关系密切.该矿床的发现对大别山北麓钼多金属成矿带寻找隐伏矿床具有指导意义.
