| Abstract:Taking the stream sediment data (scale 1颐50000) of the Small Pol mountain region as the object,the ore-forming elements portfolio of the
study area are determined to be Pb-Ag-Zn-Cu-Bi (Pb-polymetallic mineralization portfolio) and Mo-W-Sn (Mo-bearing polymetallic mineralization port鄄
folio) by correlation analysis and R-type cluster analysis. According to the above result,it is possible to make up two linear combind variables F1 (Pb-Ag-
Zn-Cu-Bi) and F2 (Mo-W-Sn). Moreover,the authority value of each element of these variables is determined by the relevant intensity of the main oreforming
elements. Two abnormal graphs of combined variables are drawn with the approach of trend-surface analysis. The result shows that the anomalies de鄄
termined by the combination of variables are well consistent with the known mineralization areas and the alteration information in the study region. In cun鄄
junction with the conditions of ore-forming geology,this paper evaluates the anomalies determined and suggests 3 potential mineral resources regions of level
-I,and 2 regions of level-II and level-III,respectively. They provide scientific evidence for further mineral search. |
