摘　　要：乌和尔楚鲁图钼矿是二连-东乌旗成矿带新发现的一处中型隐伏斑岩型钼矿床。根据最新的矿床勘查成果,详细分析了矿床地质特征、物化探异常特征、矿体及矿石特征,简要评述了控矿因素、综合找矿信息。结果表明,矿体主要赋存于花岗斑岩与英安质角砾凝灰熔岩的内外接触带中,呈拱桥状产出。空间上和成因上均与燕山早期侵入的花岗斑岩体关系密切,含矿岩体以富硅、富碱、过铝型以及w(K2O)>w(Na2O)为特征。矿区围岩蚀变作用强烈,主要有硅化、钾长石化、黄铁矿化、绢云母化、绿泥石化、碳酸盐化等。主成因类型属低品位斑岩型钼矿床,初步估算钼矿体(3341)资源量为7万多吨。乌和尔楚鲁图钼(铜)矿床的地质、物探、化探等综合找矿信息,对本地区下一步找矿工作的开展具有重要借鉴意义。Located in the Dongwuqi metallogenic belt,Wheerclt porphyry-type molybdenum deposit is newly found as a middle molybdenum deposit.The authors studied geological characteristics,geophysical and geochemical anomalies,ore body and ore characteristics on the basis of the latest exploration results and briefly review the ore-controlling factors,comprehensive to ore-prospecting information.Results show that：The ore body mainly occurs in the inner and outer contact of granite porphyry and dacite breccia tuff lava as an arch bridge.It is closely related to granite porphyry body in space and origin.The ore-bearing intrusions are characterized by enrichment of SiO2 and alkali,relatively high Al2O3 and higher K2 O than Na2 O.There are extensive metallogenic alterations such as silicifiation,K-feldspathization,pyritization,sericitization,choritization,and carbonatization.The porphyry molybdenum deposit is low grade,and primarily estimated to contain more than 7tons of ore reserves（3341）.Geological,geophysical and geochemical ore-prospecting information of Wheerclt molybdenum（copper）deposit provides an important reference for next regional ore-prospecting.
