摘要

The criterion-base iterative stepwise Backward Elimination(BE)method was used to predict Au according to the main variables(Ag,Cu,Pb,and Zn).The optimization process of the quadratic polynomial model are carried out on different trenches.Whereas,Pb and Zn with Ag×Zn and Pb×Zn are significant to determine the lateral dispersion of Au.It means Zn is the predominant element in near surface zone.Therefore,it point out that the polymetallic(Au-Ag-Cu-Pb-Zn)high-sulfidation hydrothermal veins may be related to a porphyry deposit at depth.Laterally,2D surface contour maps using kriging confirms all the results of the dispersion pattern of elements at Glojeh.
