Abstract：The West Bairendaba zinc polymetallic deposit in the middle and eastern part of Inner Mongolia is a typical hydrothermal vein-type polymetallic deposit. In this paper, element enrichment and depletion regularity, primary anomaly zoning sequence, vertical variation of geochemical parameters and the relationship between sulfur, iron and ore-forming elements in the rock samples of the deposit were studied. The results show that there exist positive anomalies of ore-forming and associated elements and negative anomalies of Ba, Sr and Na2O in the ore deposit which as a whole occurs in a depletion halo formed by the negative anomalies. The major indicator elements of the deposit include Zn, Ag, Pb, Cu, Cd, Sb and Hg, and the indirect indicator elements are Ba, Sr, Na, As, W and Rb. The axial zoning sequence of the primary anomaly in the ore deposit is Ag-Hg-Pb-As-Cd-Zn-Bi-Au-Cu-Sb-Na2O-Sr-Ba-W-Co-Mo-Rb, with the existence of the anti-zoning phenomenon of As and Sb. The high element content and vertical fluctuations of geochemical parameters show that the mineralization experienced a superimposition and complex process. The authors established an primary geochemical pattern for the ore deposit. As various types of anomalies indicate that the ore-forming geochemical system has not yet terminated in the depth, the authors infer that there possibly exist concealed blind ore bodies in the depth. The result obtained by the authors provides a basis for the prospecting work in the depth and the periphery of the ore district.
