Abstract

Abstract

106 samples were sequentially collected from a 106.5 m vertical core of the loess cover on the Diyanqinamu Mo-Ag deposit in the grassland area in the Inner Mongolia. The contents of 33 elements were measured by Niton XL3t X-ray fluorescence analyzer. After the normality test, the correlation between the contents of elements and the depth were analyzed by Kendall τ correlation coefficient method, which shows that the contents of 18 elements Mo, S, W, Te, Fe, Cu, Ni, Mn, Sb, Rb, Cs, Sn, Zn, Ti, V, Pb, Th and As from the loess cover are statistically correlated with the distances from the ore source. The long-term trends of the 18 elements were detached from the content spatial series, which were classified into several clusters. Ore-forming factors Mo-W factor and Pb-Zn factor were obtained by factor analysis, and the exponent transportation modes of the Mo-W factor were simulated. The research approach and results of this paper could be useful references for evaluating mineral resources of covered areas from the surface geochemical anomalies.
