摘　　要：在前期找矿和详查资料基础上,结合矿区岩样分析报告,综合对比了宽坪群地层、矿区石英斑岩、白岗岩及矿石中微量元素含量及其迁移富集规律,对比结果显示:矿区岩浆岩中Mo含量远高于其地壳丰度,其中石英斑岩中Mo的平均含量为26.67×10-6,浓度克拉克值达17.78,即成矿主元素Mo在石英斑岩体中明显富集,故认为成矿物质来源于岩浆岩。Combining with mine rock analysis report,we studied the molybdenum deposits of trace element of the molybdenum deposits systematically and compared the accumulation regularity of strata,mining quartz porphyry and white granite of trace elements comprehensively based on the previous prospecting material.The results showed that compared with the strata,content of Mo in igneous rocks was far higher than the crustal abundance.Quartz porphyry,in which the average content of Mo 26.67 × 10-6,and the concentration Clark value of 17.78,was strongly enriched Mo,so we hold that the forming materials derived from magmatic rocks.
