The Jinshan gold deposit is located in the Neoproterozoic Jiangnan orogen between the Yangtze and Cathaysia blocks. Gold‐bearing disseminated ores are associated with the earlier stage of NWW‐trending ductile zone, and auriferous quartz vein‐type ores show an intimate relationship with the later stage of NE‐trending brittle‐ductile zones. Fluid‐inclusion studies were conducted on the quartz veins...
Microthermometry and volumetric analysis are now widely used techniques in petroleum geology, which allow the reconstitution of the composition and P‐T trapping conditions of petroleum inclusions. However, these methods require efficient thermodynamic modeling tools of the PVT properties, coupled with compositional models for petroleum. Two methods presently available are reviewed here. The first...
Laboratory experiments were performed to help understand the fluctuations and the spike‐like anomalies of Rn in a time series that was recorded continuously at monitoring stations. One of the experiments indicated that Rn is adsorbed on the surface of sand particles and can be liberated with minor changes in the physical conditions of the containing medium. Another experiment indicated that the liberation...
