Geoelectrochemical Integrated Technology For Prospecting And Prediction Of Jienagupu Gold Mine Area, Longzi County, Tibet

The Tethys Himalayan metallurgical belt in southern Tibet is an important gold-metallurgical metallurgical belt in China.Since the closure of the Tethys Ocean,frequent geological activities in the area have provided material sources,ore-conducting structures and ore-forming space for the formation of ore deposits.In order to solve the deep and periphery gold metallurgical prospecting prediction in Jienagepu mining area of Longzi County in Tibet,the integrated GEO-ELECTROCHEMICAL technology is applied to carry out prospecting and prediction work in this area.Through the study of GEOELECTROCHEMICAL prospecting prediction in Jienagepu mining area,the following research results are obtained:(1)On the basis of previous studies and under the background of regional metallurgical geology,it is concluded that the main ore-controlling structures in this area are near-east-west and North-South structures with frequent geological activities.Through field survey,feldspar quartz gravel can be seen in the study area,and black slate can be found in some gullies.According to the data consulted and field exploration,it is considered that this area has good prospecting prospects.(2)Through the experimental study on the reliability of soil ionic conductivity,soil pyroelectric mercury release and geoelectric extraction methods in the known profiles of Jienagepu mining area,fresh GEOELECTROCHEMICAL integrated anomalies have been detected above the known ore bodies,which indicates that GEOELECTROCHEMICAL method is feasible in prospecting in this area,and also proves that GEOELECTROCHEMICAL method is feasible and effective in the permafrost area of southern Tibet plateau.(3)By using multivariate statistical analysis,there are four groups of element combinations in the study area::F1 factor element combinations:Mo-Co-Mn-Zn-Bi-Sb,F2 factor element combinations: Au-As,F3 factor element combinations: W-Hg,F4 factor element combinations: Ba.Among them,factor F1 reveals the multiple stages of geological activities in the study area;factor F2 indicates the gold mineralization stage,and indicates that As can be used as a prospecting indicator for Au in the area;factor F3 indicates that there may be intermediate-acid magmatic activities in the area;factor F4 indicates that there may be a large amount of potassium in the study area.(4)According to the unit element anomaly map,the combination element anomaly map and the geological conditions of the study area,four prospecting target areas are delineated,including 2 A-class,1 B-class and 1 C-class.It is also found that these target areas are mainly located at the edge of the study area and tend to extend outside the study area.(5)Through consulting the geological characteristics of the surrounding deposits in the Jienagupu mining area and comparing the geological conditions of the Jienagepu mining area,it is concluded that the geological background and genesis of the regional deposits are similar,and the metallurgical time is relatively concentrated.Therefore,according to the genesis of the surrounding deposits,we can guide the prospecting of the Jienagepu mining area and establish a descriptive geological model of the study area.
