摘　　要：白山钼矿床位于环准噶尔斑岩型成矿带东南缘三岔口-白山斑岩铜钼矿带。矿床产于二长花岗岩与下石炭统干墩组(C1g)的黑云母长英质角岩外接触带中。矿体呈脉状、透镜状、似层状。成矿元素以钼为主,伴生铜、银、铼、硫。目前已探明钼金属量30万吨,根据地物化综合分析研究,在矿区南部及东西外围有很大的找矿前景,是寻找超大斑岩型钼矿床的有利地区。The Baishan molybdenum deposit is located in the Sanchakou-Baishan porphyry copper molybdenum ore belt, which belongs to the southeast edge of circum Zhungaer porphyry ore belt. This deposit occurs in the exo con- tact zone of the granite, which consists of biotite felsic hornfels originated from the Early Carboniferous Gandun For- mation. The orebodies occur as veins, lens and layers, 100 ~ 3000 m long, 2 -38.4 m thick, with average Mo grade of 0.03% -0.78%. Ore metals consist of mainly molybdenum with accompanying copper, silver, and rheni- um. Currently the proven metal Mo reserve is 0.3 M tons. Based on geological, geophysical and geochemical ex- ploration information, the neighboring areas in the south, west and east parts of the current ore zone is promising for further mineral prospecting.
