| 摘 要： | 乌日尼图钨钼矿床是近年来在国土资源大调查中发现的一个大型矿床.钨钼矿体主要产于燕山期细粒花岗岩与中下奥陶统乌宾敖包组砂板岩的外接触带中,矿体多呈脉状及透镜状,且明显受构造裂隙控制；矿床成矿在不同部位其矿化形式不同.在成矿母岩--燕山期细粒花岗岩中形成浸染状矿石；同时在与含钙质的板岩接触部位形成夕卡岩型矿石,在乌宾敖包组裂隙中形成热液脉型矿石.其中热液上侵与围岩接触处的细脉状矿床最为主要；矿体围岩蚀变发育,硅化、黄铁矿化与矿化关系最为密切；矿床深部钨钼矿石呈浸染状分布于细粒花岗岩中,后者为成矿母岩；矿床成因属广义的斑岩型矿床.

| Abstract: | The large-size Wurinitu tungsten-molybdenum deposit is discovered in the Erenhot-East Ujimqin,Inner Mongolia during implementation of Land resources survey program.The ore bodies occur mainly as veins and lenses in the outer contact zone between Yanshanian fine-grained granite and sandy slate of Middle-Lower Ordovician Wubinaobao formation and are obviously controled by tectonic fractures.Mineralization is varied spatially.The disseminated ore is in the Yanshanian fine-grained granite,the skarn ore at the contact between the fine-grained granite and calcareous slate and hydrothermal ore in the fractures of Wubinaobao formation.The hydrothermal ore vein is dominant.The wall rock alteration is well developed and silicification and pyritization are closely related to ore bodies.Genetically,the deposit is the generalized porphyry tungsten-molybdenum deposit. |
