摘要
In this paper, PXRF was used to recognize lithology section and to analyze the content of Fe, Mn, Cr, Co, Ni, Ti, V, Cu, Zn, Pb, Ag, Mo, K, Ca, As, Sb, Bi, Cs, Zr and Nb along 5 drill holes in the Nihe iron deposit, Anhui Province, East China. Based on these data, the spatial distribution of these elements is obtained. The results show that 1) the areas with high values of Fe obtained by PXRF have high spatial correlation with the area with high grade of Fe delineated by chemical analysis; 2) Fe anomalies, Fe-V-Mn-Cr-Ni-Ti-Bi anomalies, Zn anomalies and Zn-Cu-Cd anomalies are good indicators for Fe mineralization, Cu and Zn mineralization, respectively; and 3) K and Ca anomalies are good indictors for potash feldspar alteration and anhydrite alteration, respectively.
