摘　　要：在内蒙古西沙德盖钼矿床详查工作的基础上,根据大量的地质信息对矿床进行了分析,提出矿床成因类型为中型斑岩钼矿床,总结出矿床主要找矿标志。矿体围岩为云英化岩斑状钾长花岗岩,蚀变主要有云英岩化、硅化、钾长石化,其次是高岭土化、绢云母化、黄铁绢英岩化,围岩蚀变产生的矿化对找矿具有指导性意义。This study is based on the detailed geological exploration of Xishadegai Molybdenum Deposit in Inner Mongolia. The deposit is analyzed according to abundant geological information. The genetic type of the deposit is medium-sized porphyry molybdenum deposit, and the indicators for deposit are summarized. The surrounding rock of the ore body is greisenization porphyritic moyite. The main alterations are greisenization, silicification and potash feldsparization, and the other alterations are kaolinization, sericitization and beresitization. The mineralization pro- duced by the wall rock alteration is instructive for prospecting.
