Extraction And Assessment Of Geochemical Anomaly Information Of Aoteaoerla Area In East Tianshan

Trace element geochemical anomaly information extraction and evaluation isdone by the distribution of elements in geological studies, abnormal, abnormalinterpretation and evaluation, thus delineating target prospect area and a prospectingprospecting method. Among them, the element anomalies determine the lower limit ofthe basic content of exploration geochemistry, geochemical also key. In this paper,Xinjiang Aoteaoerla regional geochemical survey data, nine elements identified in thestudy area of anomaly thresholds and multivariate statistical analysis of the data todetermine the combination of ore-forming elements, and the interpolation factor score,compared factor score contours and single element anomalies in order to obtainsimple, fast and accurate regional geochemical data processing method, whichprovides for such a reasonable delineation of regional geochemical anomalies andprospecting targets preferred to provide a scientific basis.Cuttings were collected from the study area675geochemical samples weremeasured Au, Ag, Bi, Cu, Mg, Mo, Pb, Sb, Zn and other9kinds of element content.The use of correlation analysis, cluster analysis, factor analysis and other methods tostudy mathematical geology paragenesis laws of each element and the mainore-forming elements combined abnormalities. Nine elements can be divided into fourcombinations of elements, combinations of the first group of elements F1factor isPb-Zn-Mn, a second group of elements of F2factor is Mo-Sb-Bi, a combination of thethird group of elements F3factor is Cu-Ag, the fourth group of elements F4factoronly Au. Which, F3factor combinations Cu-Ag ore-forming elements can becombined as the main study area, with the formation of copper-silver polymetallicmineral potential.By determining the lower element and circle orders element anomalies, whileusing a combination factor score method delineated exceptions. Contrast combinationof these two methods delineated exceptions derived factor score combination methoddelineated anomalies and copper mineralization in the study area are basically thesame distribution of points, so factor score method to obtain the F3region as seekinghydrothermal copper polymetallic ore focus on prospecting areas in the region can beused as prospecting targets for future work. At the same time, it also shows that the factor score method in the delineation of the feasibility of a combination ofabnormalities for future geochemical anomaly extraction provides a new theoreticalbasis.
