内蒙古乌兰矿区多金属矿地球物理、地球化学特征研究

Research on the Geophysical and Geochemical Characteristics of Multi metallic Minerals in Ulan Mining Area,Inner Mongolia

为了解内蒙古东乌珠穆沁旗乌兰矿区的多金属矿成矿地质条件,研究成矿规律,通过全面收集研究区域地、物、化和矿产等成果资料,采用大比例尺地质测量、物探和槽钻工程等方法手段,同时配合物探激电测深测量、激电联合剖面测量、1∶10000高精度磁法测量,大致查明了矿区内地表矿化蚀变带的数量、分布、形态、规模、产状,了解了矿区地层、构造、岩浆岩与成矿的关系,为下一步普查找矿工作奠定了基础。

In order to understand the geological conditions of polymetallic mineralization in the Ulan mining area of Dongwuzhumuqin Banner,Inner Mongolia,and study the mineralization laws,comprehensive collection of regional geological,physical,chemical,and mineral data was carried out.Large scale geological surveys,geophysical exploration,and trench drilling engineering methods were used,combined with geophysical induced polarization depth measurement,induced polarization joint profile measurement,and 1:10000 high-precision magnetic method measurement.The quantity,distribution,morphology,scale,and occurrence of surface mineralized alteration zones in the mining area were roughly identified,and the relationship between the strata,structures,magmatic rocks,and mineralization in the mining area was understood.This laid the foundation for the next step of survey and prospecting work.
