The Au has a close correlation with As, Pb, Ag and Cu. Geochemi- cally, the deposit is characterized by relatively enrichment in LREE with moderate or lower Eu negative anoma- ly. Sulfur isotopes appear as single and deep source, and lead isotopes indicate the Pb is from the earth＇s mantle and crust, which mainly are orogenic belt Pb, the ore-forming fluid has a temperature of 215~C -350~C and a low salinity with a mixture of characteristics of magmaitc hydrothermal and meteoric water. The ore-forming age is 111. 1 - 111.4 Ma. The deposit is formed in mineralization and precipitation of metallogenie materials caused by the mixture of the magmatic hydrothermal fluid and meteoric water.展开更多

The gold degree is lower. Au is closely related to the Ag, Cu, Pb, As and Hg elements. The upper sillealite has Eu and Ce negative anomaly, and the lower sillealite 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 Ph isotope has the character of the mixture origin of crust and mantle that is mainly dominated by Pb in the orogenic beh. The oreforming tluid temperature is 180℃-244℃ , characterized by magmatie 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 overtlowing near the earth＇ s surface and leading to the metallogenic funetion and the metallogenic substar,ee deposition.展开更多
