| Abstract: | Jianchaling gold deposit in Shanxi-occurs within contact zone of ultrabasic rock. The type of geochemistry of the gold deposit is Au-Ni-Cu-Ag. Characteristics of elements assemblage, rare earth elements, stable isotope of the gold deposit indicate that the ultrabasic rock is not only host rock of the gold deposit but also source rock of the gold deposit. S of the gold deposit comes from the mantle and country rock. Acidic magmatic hydrothermal solution in 400 my not only causes metamorphism of the ultrabasic rock but also dissolves part of gold which is scattered in the ultrabasic rock. Au precipitated from ore forming fluid and formed gold deposit when ore-forming fluid immigrates into contact zone of the ultrabasic rock due to P.T decreasement. |
