摘　　要：黑龙江大卜场钼矿化体赋存于花岗斑岩体与正长花岗岩体接触带及构造破碎带中。矿化体所在位置范围内表现△T负异常、中等极化率中阻激电中梯异常,成矿元素Mo异常极为发育。根据区内的地质、物探、化探综合研究表明,大卜场钼矿化体成因类型可能为花岗斑岩型,矿化体可能为燕山期成矿。The Dapuchang molybdenum mineralization in Heilongjiang Province occur mainly in the contact zone of granite porphyry and syengranite,and also in the tectonic fracture zone.The mineralization area had△T relative negative magnetic anomaly,showed moderate polarization and intermediate resistance characteristics using induced electric medium gradient method,and molybdenum anomaly were strong.Comprehensive study on the geological,geophysical and geochemical characteristics of the molybdenum deposit showed that the genetic type of the Dapuchang molybdenum deposit may belong to granite porphyry type molybdenum deposit which formed in Yanshan period.
