Sipingshan gold deposit is gold-bearing sillcalite in type�� There only exist a few kinds of sulfide in the ore and it is lower in content�� The gold degree is lower�� Au is closely related to the Ag��Cu��Pb��As and Hg elements�� The upper sillcalite has Eu and Ce negative anomaly��and the lower sillcalite has Eu positive anomaly�� however��the hot spring cemented breccia and rhyolite porphyry have Eu negative anomaly; the S isotope component has deep-seated magmatic sulfur and terrestrial sulfate characteristic; and the Pb isotope has the character of the mixture origin of crust and mantle that is mainly dominated by Pb in the orogenic belt�� The oreforming fluid temperature is 180��-244�棬characterized by magmatic hydrothermal and meteoric water; and the ore-forming age is 87 Ma�� The deposit was formed by the metallogenic fluid in the tectonic fault zone overflowing near the earth’s surface and leading to the metallogenic function and the metallogenic substance deposition��
