温多尔哈尔铜矿床地质特征及找矿前景探讨

温多尔哈尔铜矿床位于华北板块华北北部陆缘增生带鄂尔多斯坳陷,区域上为狼山-渣尔泰元古代、古生代多金属成矿带。通过对该矿床的地质特征研究和物化探综合分析,阐述了温多尔哈尔铜矿床的成矿特征、控矿因素及成矿前景。该矿床分南北两个矿段,北矿段主要为铁矿化,南矿段主要为铜矿化。南矿段含炭质石英板岩的出露,对物探工作成果分析带来较大干扰,不利于直接作为找矿线索。南矿段地层控矿特征极为明显,铜矿体局限分布于石英岩地层中,南矿段石英岩地层为后续找矿工作的重点。

Geological Characteristics and Prospecting Potential of the Wenduoerhaer Copper Deposit in Inner Mongolia

Abstract: The Wenduoerhaer copper deposit is located in the Ordos depression, the continental margin accretion zone north of the North China plate, and belongs to the Langshan - Zhaertai Proterozoic - Paleozoic polymetallic metallogenic belt. This paper analyzes its geological, geophysical and geochemical characteristics, and illuminates its metallogenic features, ore-controlling factors and prospecting potential. The deposit is divided into the north and south ore sections, and the northern section is dominated by iron mineralization, and the southern section is primarily copper mineralization. Outcrops of carbonaceous quartz slate in the southern ore section cause a serous interference to geophysical surveys, and cannot be used as direct prospecting clues. On the other hand, mineralization in the southern section is obviously controlled by strata, and the copper ore bodies are confined to quartzite formation which should be regarded as the focus for future prospecting.
