Abstract:
An organic facies is defined as a mappable stratigraphic unit containing organic matter (OM)of a particular genetic type in cartaain abundance. A new organic facies classification，which is based on indicative genetic kerogen(OM)type。is proposed. The ...

Abstract:
For a long time, ripple marks were often regarded as one of sedimentary indicators of shallow water, but large quantities of them were also found in bathyal terrigenous elastic turbidites of Upper Triassic of west Qinling Mts. The ripple marks charac...
