摘　　要：小秦岭地区是著名的多金属成矿区,其形成与酸性浅成-超浅成花岗斑岩体有关,钼矿床直接产于岩体内外接触带及其附近,有的斑岩体即为钼矿体;通过对斑岩的性质分析,阐述了含钼斑岩的成因、形成环境、构造机制及其与钼矿床的成因关系。Xiaoqingling area is a famous polymetallic ore-forming zone associated with acidic shallow to super shallow granitic porphyry in genesis, with molybdenum deposit occurring in inner and out contact zones of magmatic rocks, some porphyry being molybdenum orebody itself. Based on the analysis of porphyry＇s properties, the genesis of ore bearing porphyry, genetic relations of molybdenum deposit with forming environment and structure mechanism were expatiated.
