摘要
The Zhunsujihua copper-molybdenum deposit in Inner Mongolia is a typical hydrothermal vein type deposit. The element content and anomaly characteristics of the surface soil indicate that the elements exhibit a zonal distribution on the plane. This zonal distribution is centered by the surface mineralization outcrop, outward with a broad zone of Mo-Cu-W-Bi zone, In-Zn-Ag-Cd zone, and the outermost Pb-As-Sb zone in turn. This zonal sequence conforms to the distribution of elements in typical middle-high hydrothermal deposits. The combined anomalies of the major metallogenic element Mo and accompanying elements Cu, W, In and Bi are evaluated by geologic accumulation indices, and four target areas are determined. According to field investigations and project verification, deep-seated resource forecast is suggested to conduct in the target areas of I and II, and further investigations and verification need to be carried out in the target areas III and IV, and it is expected to discovery skarn mineralization in target area IV. This study is of great significance for deployment and implementation of the next exploration in the Zhunsujihua district.
