Geochemistry of hydrothermal gold deposits: A review ...

2011-7-1  3. The geochemical behavior of gold in hydrothermal systems. The occurrence of gold mainly depends on temperature, pressure, pH values, Cl − concentration, and fugacity of H 2 S in a hydrothermal system. Gold mostly occurs as AuCl − 2 in a system with temperature higher than 400 °C (Gammons and Williams-Jones, 1997), and with decreasing temperature being the primary

Metal source of gold deposits in the Jiaoxibei area ...

2021-9-29  The metal source of gold deposits in the Jiaoxibei area, eastern China, has been investigated by many researchers, but no consensus has been reached so far. In this study, three typical gold deposits, the Xinli, Jiaojia, and Dayingezhuang deposits, were selected for trace element analysis of gold and pyrite to constrain the metal source.

Newly published models suggest that some orogenic and Carlin-style gold deposits formed by the remobilisation of trace elements during interaction with hydrothermal or metamorphic fluids from early sedimentary pyrite that was enriched in Au, As and Te. The released trace elements are transported by the fluids to favourable trap sites where they are deposited.
