Abstract

Abstract

Portable X-ray fluorescence spectrum (PXRF) is a new analysis technique in-situ and is usually applied in both geochemical research at geological outcrop scale and heavy metal pollution assessment in soil. In this study, 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, 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. These results indicate that PXRF is a convenient, quick, practical, reliable, and nondestructive technique of low cost for identifying of mineralization and alteration along drill in the field.
