Figure 8: Diagram of determination of organic Facies by using the ratio of changes of HI Vs OI. Characteristics of specified range include: A: environment which is very regenerating. AB: marine regenerating environments are related to marine or lake regenerating environment: environment including marine and continental organic material and sedimentation in oxidant conditions. C environment with average sedimentation speed. CD: deep environment next to Orogenic point’s D continental environment with extreme oxidant [16].
