Abstract:

The study area is located in the north zone of Beishan Mt,where the ore-forming geological condition is favorable, and the anomalies of the 1∶200 000 stream sediment survey are outstanding. Meanwhile, the Elegenwulanwula porphyry Mo(Cu)deposit is also located in this area, where the 1∶50 000 soil geochemical survey has been conducted by the authors. Taking the soil geochemical data as the material and the geology cognition as the basis, this paper has studied the geochemical data characteristics, geochemical field characteri-stics and integrated anomalies characteristics. According to this study,the authors believe that Mo, Cu and Au are the main metallogenic elements in this area, the volcanic horizon of Xianshuihu Formation is the main meta-llogenic strata, and the Carboniferous granodiorite is the main metallogenic intrusion. All the integrated anomalies can be divided into five types, among which those related to the porphyry Mo(Cu)metallogenic system and Ordovician geological formation-structure are the key points for the future study and prospecting.

Key words: soil survey, geochemical field, integrated anomaly, porphyry Mo(Cu) metallogenic system, Elegenwulanwula, Inner Mongolia
