Application of Geophysical and Geochemical Exploration Results in Prospecting Prediction: Taking Pangjiagou-Xiajinbaogou Au-Ag Polymetallic Ore in Hebei Chengde as an Example
Abstract:
Pangjiagou-xiajinbaogou Au-Ag polymetallic ore in Hebei Chengde magmatic activity is very strong, mainly Late Jurassic - Early Cretaceous of granite and Late Yanshanian alteration of acidic rocks, archean metamorphic rocks and Middle Proterozoic strata containing mainly gold seam. Studies show that the area is insignificant on main rock resistivity, and all kinds of mineral body, mineralized rocks Fs> 2.4%, gneiss containing high gold abundance, gold body, auriferous quartz veins are greater than 2.4% Fs,can be used as an indirect sign on geophysical prospecting. Sb, As, Pb, Ag, Au and other elements of the exception can be used as indirect signs on geochemical prospecting. After considering this area geophysical, geochemical characteristics analysis of, binding studies geological conditions, prospecting method using the analogy prediction target region, the success of the orebody found.
