摘　　要：三个顶子钼锌矿床属夕卡岩型矿床,矿体呈脉状产于奥陶系石缝组大理岩层间断裂中,成矿作用与燕山期斜长花岗岩、花岗斑岩关系密切.钼矿体多产于夕卡岩内,辉钼矿常于石榴石集中处富集,呈浸染状或细脉状.系统总结了三个顶子钼锌矿床的地质特征及矿床控制因素、矿床成因,并分析归纳出该矿床赋存富集规律,确定了该矿床的找矿标志.The Sangedingzi Mo-Zn deposit belongs to skarn deposit, with ore bodies occu,xing as veins in the interbed faults in the marble of Ordovician Shifeng formation. The metallogenesis is closely related to Yanshanian plagiogranite and granite porphyry. The molybdenum ore bodies favorite skarn, with molybdenite commonly enriched at the concentration of garnet, in dissemination or veinlets. Based on the geologic characteristics, controlling factors and genesis of the deposit, the regularities of the occurrence and enrichment, as well as the prospecting indicators are determined.
