The Berezitovoe gold-polymetallic deposit (Upper

2016-5-1  Gold-polymetallic complex is characterized by the irregular distribution of nests, veinlets, and dispersed impregnation of sulfide minerals in the metasomatites. The size of the sulfide nests does not exceed 20–30 cm, and the veinlets are no more than 3–5 cm. Replacement textures are common.

Geochronology of the giant Beiya gold-polymetallic

The Beiya gold-polymetallic deposit, located at the junction of the “Sanjiang” Tethys–Himalaya orogenic belt and the Yangtze craton in southwestern China, is the largest gold deposit in the region. Mineralization mainly occurs in skarn, which formed along the contacts between porphyry intrusions and limestone host rocks.

Genetic Types and Metallogenic Model for the

example, the polymetallic copper–gold deposits within the Tongling ore district were originally interpreted as typical skarn-type deposits (Guo Wenkui, 1957; Guo Zongshan, 1957; Zhao Bin, 1989). The orebodies mainly occur in contact zones between the Yanshanian intrusions and carbonate rocks, where the skarn mineral assemblages are well-developed.

Divining gold in seafloor polymetallic massive sulfide

2019-6-29  In sediment-hosted (SED) systems, the much higher pH stabilizes Au(HS) 2 − and keeps gold in solution to very low temperatures, after the precipitation of chalcopyrite, sphalerite, and galena, resulting in Au-poor polymetallic sulfides and very late-stage deposition of gold, commonly with amorphous silica. In arc-related (ARC) systems, gold deposition occurs at somewhat higher temperatures than in the MOR case, in part because the fluids start with higher gold

Divining gold in seafloor polymetallic massive sulfide

2019-6-29  In ultramafic-dominated systems, gold deposition occurs earlier owing to the lower stability of the AuHS° complex at low ƒO 2 (FMQ buffer). Gold deposition begins at 250 °C, before sphalerite deposition and is slower, requiring 75 °C of cooling to deposit > 90% of the gold.
