The indiction of the organic in basin for the process of basin-mountain coupling

The study of organic evolution in basin play a significant role in recognizing the process of basin-mountain coupling.Orangic and its offstring are influenced by temperature,time and pressure etc.On the basis of vitrinite reflectance,organic inclusions and organic geochemical study,we can built the tectonic basin-mountain formation system,analyze the uniformed temperature-pressure field and tectonic stress field of undergroud fluid,and therefore recover the process of basin-range coupling.
