陕西潘河钼矿床位于华北板块与扬子板块拼接消减带的北秦岭东西向洛源-石门-马超营断裂与铁炉子-黑沟-栾川断裂带之间,南西距蟒岭岩体约10 km.它属于元古界长城系宽坪群上段绿片岩系掩盖下的似层状、层状矿体,产于元古界长城系宽坪群下段一套浅变质绿片岩与(矽卡岩化)大理岩的不同岩性层间接触界面间.区内岩浆活动、矿体产出形态、...

Geological characteristics and genesis of Panhe molybdenum deposit in Shangluo, Shaanxi Province

The Panhe molybdenum ore deposit is located in EW-trending Luoyuan-Shimen-Machaoying and Tieluzi-Heigou-Luanchuan faulted zones of North Qinling along the collage subduction belt between North China plate and Yangtze plate, some 10 km from the Mangling intrusive body. It consists of stratoid and stratiform ore bodies covered by greenshist of upper Kuanping Group in Proterozoic Changcheng System. Ore bodies occur along the interlayer contact zone between epimetamorphic greenschist and skarnized marble in lower Kuanping Group. Modes of occurrence of ore bodies, ore textures and structures and mineralization enrichment characteristics are all closely related to regional main folds and faults as well as joints and fissures. Based on geological, ore body and wall rock alteration characteristics in the ore district, this paper has made a tentative discussion on the genesis of the ore deposit as well as the ore-control factors.
