八渡钼矿地质特征及找矿潜力分析

摘要

Badu molybdenum deposit is located in Caledonian folding belt of North Qinling, the ore body occurs mainly in the Middle Proterozoic Qinling group stratum,and ore body shape,occurrence is controlled obviously by S-N trending fault or concentrated fissure zone in structure,the ore body shows low thickness,veins set and high grade. Main metal mineral in the body are molybdenite and chalcopyrite . The genesis of the deposit belongs to the porphyry type deposits in broad sense. The research shows that there is great prospecting potential in the deep ore-body hidden part,extending part of known ore belt as well as the contact zone of granite and gneissic rock.%八渡钼矿床位于北秦岭加力东褶皱带，矿体主要赋存于中元古界秦岭群地层中，矿体形态、产状明显受SN向断裂或密集裂隙带控制，矿体厚度小、条数多、品位高。金属矿物以辉钼矿、黄铜矿为主。矿床成因属广义上的斑岩型矿床。研究表明，在矿区深部、已知矿带的延伸部位及岩体周边有较好的找矿前景。
