Study Of Medium And Large Scale Exploration Geochemical Method In JiaPiGou,Jilin

Jiapigou gold deposit in the structure of the earth belong to the southern flank of Jilin-Heilongjiang block in eastern Siberia and in the eastern section on the northern edge of the NCC,Mining area has the very good ore-forming geological background.Due to the existence of the mining of ore control tectonic extension area,mineralization are closed,Jiapigou mining area periphery also has great potential for gold prospecting.Through the Jiapigou mining area and its periphery 80km~2 zone conduct geochemical survey,Which is sampling medium for cuttings.within the range of anomalies delineated to carry out detailed geochemical survey,further narrowing the prospecting target areas,through these work,The knowledge obtained is as follows:1?From the census area ground cuttings measurement result,gold anomalies delineated can well reflect the known gold deposits,The known gold deposits are located in the gold anomalies delineated by range.the grid method for multipoint combination of coarse grained lithic measurement method is suitable for the geochemical survey in the jiapigou area,It is worthy of popularizing in the landscape application.Cuttings measurement discovered new gold anomalies with ore-prospecting significance in jiapigou mining area periphery,It shows that there still has some prospecting potential,Which Provide a new target for one of mine looking for gold mine resource in jiapigou area.2?Using 1:10000 geochemical survey conduct anomaly inspection on the west side of erdaogou gold anomaly area.Sampling method is still the cuttings measurement.Framed the multiple gold by measuring the highest content of more than 100 ng/g gold anomalies,and associated with Ag,As,Sb,Hg,Pb,W elements such As exception,It deserves further exploration engineering,to verify this exception,Which is expected to find gold ore body of economic value.3?Look from the element combination,jiapigou gold field have two different types of element combination,the jiapigou gold deposits in the east of fracture enrich Au-Ag-Bi-Pb-W,and lean As,Sb,Hg element combination,such as mine in this area,three switch ore,the north ditch,etc;However Jiapigou fracture near the element combination is complex,in addition to the enrichment of Au-Ag-Bi-Pb-W the anomalies of the elements,but also enrichment of As,Sb,Hg abnormal indicator elements,such As erdaogou,Jin Ling,etc.There may exist two different types of mineralization types in Jiapigou area.
