The Xiaotieshan concealed polymetallic deposit is genetically a submarine volcanic eruptive-sedimentary deposit. Its

orehosting strata contain fairly abundant Cu, Zn, Ba, Ag and Co. Within the ore field and the ore deposit, these elements form

distinct primary anomalies, which are superimposed on the mineralization sector. In the extending direction of the ore body, the

distribution and association of the primary anomalies assume axial zoning, with the frontal elements being I, Na2O, Li, the

elements closely associated with the ore body being Cu, Zn, Hg, Au, Pb, Ag, Bi, Sb, As, and the rear elements being Cd, Mo, Co,

Sn. From the upper part of the ore body to the rear part,［(w（Na2O）×w（Li）］/［w（K2O）×w（Rb）］ decreases regularly. The

element association in the hanging wall is obviously different from that in the lying wall: the hanging wall is enriched with

siderophile elements, while the lying wall has abundant thiophile elements. These indicators are surely of some significance in

the evaluation of anomaly prospects and mineralization-denudation extent.
