摘 要: | The sedimentary-reformed ore deposit is one of the main types of strata-bound ore de-posits. The elements for the formation of sedimentary-reformed ore deposits in Chinamainly include Pb, Zn, Hg, Sb, As, U, Cu, Fe as well as S(pyrite), F(fluorite), Ba(barite)and Si(crystal). In this paper, the background content values of ore-forming elements inthese deposits are summarized, the association types of ore-forming elements in these depositsdivided and the geochemical characteristics and formation mechanism of these associationtypes discussed.
