Abstract

According to the Baimianshan metallogenic forecasting area geological investigation to the west of Dabaoshan Mo deposit, we know that this area highly developed fault structures, mainly for the NW, NE and nearly NW three groups, among them, the NW fracture formed in the earliest time while NE the last. Along the NW and NE fault structures, we can see lots of suffer basic rock vein intruded. Following our investigation, we also find that along the fault zone of the surface existing multiple rock alteration and antimony lead-zinc pyrite mineralization points. Based on the test analysis in this area of surrounding rock and magmatic rock samples (ICP-MS), and from mineralization and geochemical characteristics of trace and rare earth elements reflecting the region is likely to have good metallogenic environment, combination of various metallogenic geological conditions and the predecessor's research of geochemical exploration work, we can conclude that there has ore-forming geological body which is not far from underground, and provided sufficient material sources for this region mineralization. Through the metallogenic information in this paper, we predict that between 500~800 meters underground in the mid-west of Baimianshan may be a considerable scale deposit of low temperature skarn type and zinc silver multi-metal.
