The Geophysical And Geochemical Exploration Method In WuDaoGou Prospecting Application

This paper summarized the geophysical and geochemical exploration method inWuDaoGOU region for ore in the role. Through the area, Neigujin factory eight branchchannel upstream and599.3highland three ore prospecting examples, of main stratum,igneous rocks, metamorphic rocks, geochemical characteristics, structure, physicalproperties, electrical characteristics as well as high magnetic characteristics are discussedin detail. Summarize the five trench region mining geological characteristics, geochemicaland geophysical prospecting, and finally verified the prospecting effect.From five channel regions of the three abnormal verification process can be seen, thecomprehensive geochemical, geophysical information in shallow overburden area,metallogenic belt has convenient accurate prospecting effect. Integrated the research cansee,1:5million water geochemical exploration is to choose key prospecting work areaeffective means;1:2and geochemical anomaly and mineral surface position (of) thepositions of the body have a certain level of migration, but in the terrain below not bigcase, abnormal center distance (of mine) body small shift; shock electrical abnormalities,when low resistance background the small range is a high resistivity anomaly and lowpolarization background the small range and high polarizability anomalies are buckled,indicating deep underground may be mine (of) body; high precision magnetic survey inthe area of negative anomaly can accurately reflect the intrusive body deep position, sothat the delineation of ore control tectonic zone range, but the range is bigger, need tocooperate with the IP anomaly and geochemical anomalies, comprehensive utilization.Through the three abnormal area of geophysical and geochemical data ofcomprehensive research and analysis, that in Heilongjiang Province in shallow cover areasusing1:5million stream sediment anomaly delineation of constituencies, area with highmagnetic anomaly determination of ore-controlling structure of1:2million range, streamsediment anomaly identified concentration center, combined with the IP anomaly in the "low " abnormalities in determining the position of the gprospecting method is an effectivemeans in.
