Geochemical Anomaly Characteristics And Prospecting Potential Evaluation In The Saertuohai Gold Deposits,Tuoli County,Xinjiang

The Saertuohai is located in the Tuoli County of Xinjiang Oygur autonomous region,the deposits is located in the east of Juggar,in the east of chromium,gold,tin,iron,copper,mercury,graphite,crystal,coal metallogenic belt.The metallogenic belt is rich in metallic and nonmetallic minerals.This paper closely combines the research task,choose the Saertuohai Gold deposits,Tuoli County,Xinjiang as research object,strive to deal with a large number of geochemical data,study the geochemical anomaly characteristics and combined with the geological background and conditions of mineralization,make a scientific evaluation of ore-prospecting potential,In this paper,the iteration method is used as a traditional method to deal with the data of the test results of rock samples,in the case of the abnormal lower limits of every element in the area has been obtained,the parameter values of main elements are calculated,used the clustering method to study the paragenetic association of 14 elements,and the anomaly characteristics of single element,and so on.The prospecting targets is delineated and the prospecting potential of the target area is evaluated.In this pater,the following conclusions are obtained:1.The layers of the gold deposits are mainly basic volcanic tuff with lithic tuff.This formation rock has a high Au background value,which is Ore bearing strata in thhis area,and can provide the sources of Au element.2.The combination relationship of elements that reflect a certain geologygeochemistry environment,is the correlation between the display element.The result of R-type clustering showed that the relativity of As,Hg,Pb,Bi elements is very obvious,and the coefficient of correlation> 0.6.It is confirmed that there is a close genetic relationship between Au and As,Hg,Bi,Pb,from the analysis of the main ore-forming elements in various rocks,so As,Hg,Bi,Pb should be important marks of this gold area.3.The analysis result of single element anomaly characteristics showed that the gold element anomaly zones are mainly distributed in the mining area of the central position,and the linear distribution is obvious,single outlier has large scale,and the abnormal lining is the largest,with an area of 0.63km2,in the other areas,the abnormal distribution of gold element is sporadic,and the abnormal range and intensity are relatively small.Therefore,the prospecting direction is the middle part of the mining area.4.The outlier of gold in the prospecting target area roughly linear state by northeast-east direction,the outlier of gold is growing,there are more than 10 concentration center of grade 4.The phenomenon of the linear distribution of outlier indicated that the gold ore is hidden.5.The prospecting target area has good ore-forming geological conditions,tectonic conditions,ore bearing hydrothermal activities were strong,has a close relationship with gold mineralization alteration products of quartz veins and silicified rocks,pyrite and carbonate,arsenopyrite growth.The results show that the target area has great potential for ore prospecting and has a good prospect for ore prospecting.
