Yongzhang Zhou (): Geochemistry and metallogenetic mechanism of the Hetai gold field, Southern China. PhD Thesis, University of Chicoutimi (Québec), Canada. Yongzhang Zhou (): Altered ductile shear-zone host type of gold deposits from South China. Integrating the evidence obtained from regional geology, ore deposit geology, fluid inclusion and C–H–O isotope geochemistry, we conclude that the Huachanggou gold deposit is best ascribed to be an orogenic‐type system formed in the tectonic setting of the north‐vergent oceanic plate subduction along the Mian‐Lue Suture during the Cited by: Shear zone-hosted gold deposits in China can be divided into four types: ductile, brittle-ductile, ductile-brittle and brittle, of which the ductile and brittle types are the basic ones. All these types of gold deposits have their own geochemical characteristics. The Hetai gold deposit in Guangdong Province, for example, is a mylonite-type gold deposit in a ductile shear zone.
The Xiaoqinling gold field is the second largest gold producing district in China (Chen and Fu, , Chen et al., ), and has more than gold-bearing quartz veins with a proven reserve of t Au and an estimated reserve of t Au (Zhou and Yao, ).Located on the southern margin of the North China Craton (NCC), it is the northernmost part of the Qinling Orogen (Fig. 1A . The characteristic structures of the Precambrian cherts from the Gusui section, Guangdong, China, include bedded structure, laminated structure, massive structure and pseudobrecciated structure. The chert is characterized by consistently low abundance of TiO2, Al2O3 and most trace elements. Howevver, it is enriched in Ba, As, Sb, Hg and Se. In Al-Fe-Mn ternary diagrams, it fells into the. The field relationships and zircon U–Pb ages of the two granitic plutons suggest that gold mineralization is coeval with or slightly younger than the emplacement of the Jiancaowan Porphyry. Therefore, both the porphyry and deposit formed during the post-collisional stage of the Qinling Orogen.

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 °C (Gammons and Williams-Jones, ), and with decreasing temperature being the primary mechanism causing gold.

Zhou Yongzhang, Geology and Geochemistry of Hetai Gold Field, Southern China, Guangzhou: South China University of Technology Press, , 53– Google Scholar 8. Based on the results of the project “Geological and geochemical study of Hetai gold deposit field in South China”, a mineralization model was established, which provides theoretical criteria for exploring similar gold deposit types.
