CHIM—Geo-electrochemical Method To Research On Prospecting Forecast In The Wuliying Census Area Of Huadian City,Jilin Province

This thesis is based on the project of the cooperation between the Institute of concealed deposits of Guilin University of Technology and The first detachment of the Chinese People's Armed Police Gold Force.In order to solve the problem that the geochemical prospecting method is not accurate in the Wuliying census area,so on the basis of the Armed Police Gold Force have completed the prospecting work,we carry out the CHIM—Geo-electrochemical Integration technology prospecting research work in the Wuliying census area.And mainly come to the following recognizes.1.Summarizes the geological data of the Wuliying census area,and through the field survey and verification in the alteration zone found on silicification and pyritization alteration mineralization,and the broken belt is mainly distributed in Fanjiatun stratum,controlled by NW torsional fault,consistent with the information records.Therefore,the main prospecting site is the broken alteration zone of silicification and pyritization that located in the Xinli village-Dadingzi Anticline flanks of Fanjiatun stratum,and controlled by NW torsional fault.2.Study on the feasibility of ore prospecting by using the CHIM—Geo-electrochemical in TC006 coastean with weak mineralization,the results show that the electrochemical anomalies are also affected by the weak mineralized fracture zone.In addition to Ag and Bi,the geoelectric extraction element with the trough sampling analysis of Au content increased the abnormal reaction better.Therefore,it can be determined that geochemical integration technology has good prospecting effect in this area.3.By means of fractal statistical analysis and combination the analysis of element content,we think the most promising potential is Au,Cu,Pb and Zn in the Wuliying Census area,and followed by Mo,Bi elements.On this basis,combining the results of cluster analysis and factor analysis,it is concluded that the combination of the best elements in the Wuliying census area is the(Cu-Pb-Zn)middle and high temperature polymetallic metallogenic element combination and Au independent main ore-forming element combination.4.Based on the regional mineral geological data,according to the Armed Police Gold Force on the area around the mining points of the survey results,We think that the early Yanshan period and Variscan's granite intrusive mass can form the contact metasomatic type and hydrothermal deposits in this area.The Main mineral species is gold,copper polymetallic ore.This conclusion is consistent with the results of the potential element analysis of the geoelectric prospecting.5.if the single element Au anomaly region appears as a leading edge halo element combination Sb-Hg anomaly,and the soil ionic conductivity anomaly and thermal release of mercury anomaly are better,we can be considered to find hidden gold-based.If the relationship between the combination of Cu-Pb-Zn element anomaly zone with the Ag-As-Mo-Bi element,conductivity and heat release mercury anomaly is better,we can be considered to find concealed copper lead zinc polymetallic ore.6.Under the guidance of geological prospecting signs and geochemical chemical prospecting signs,in the Wuliying Geographic work area delineated twelve target area,among them five?type target area,five ? type target area,two ? type target area.Based on the comprehensive analysis of each target feature and its ore prospecting evaluation,it is considered that the target area of the ? type has the most potential for ore prospecting.So it is possible to give priority to ? type target area for engineering verification.
