PROSPECTING TARGET PREDICTION OF GOLD-COPPER-MOLYBDENUM DEPOSITS IN GEGENTAI-XIAOHEISHAN AREA OF MOLIDAWA QI, INNER MONGOLIA

Gegentai-Xiaoheishan area in Molidawa Qi of Inner Mongolia is located in the East Ujimqin Qi-Nenjiang Cu-Mo-Pb-Zn-W-Sn-Cr metallogenic belt in the northern-central Daxinganling Mountains. Based on the comparative analysis of metallogenic geological setting of regional typical deposits in the study area and ore-controlling conditions, it is concluded that Gegentai-Xiaoheishan area has the metallogenic potential of hydrothermal Au-Cu-Mo deposits, shear zone-type Au deposits and porphyry Cu-Mo deposits. Through the statistical method of information element extraction of favorable ore-controlling conditions and factor assignment, the prospecting target areas for gold, copper and molybdenum deposits in the area are predicted, which provides reference for the regional geological survey and prospecting in the future.
