The numerous micrograined_disseminated gold deposits in the Triassic basins of Jinya and Youjiang, Guangxi, are all located both in the margins of underwater carbonate platforms and in the top part of the arc faults of the Triassic basins. The investigations into the inorganic and organic geochemistry by the previous researchers and the present authors have concluded that the metallogenic materials and fluids in the Jinya gold deposits originated from the sedimentary basins. In this way, both the sedimentary structural analysis and the fluid dynamic analysis have been made of the terrain margins. The application of the fluid potential theory and the digital simulation technology concludes that metallogenic fluids originating from the basins tend to be concentrated at the abnormal pressure both in the marginal slopes of the terrains and in the top part of the arc faults. This conclusion serves as a theoretical basis for the gold exploration in this region.
