Abstract: This paper studies different kinds of source rocks including coals, carbonaceous mudstones, oil-shale, argillites and limestones collected throughout China and reports the important results as follows: There are great differences of vitrinite reflectance values (R0% ) formed under the thermal process with same simulating temperature among different kinds of source rocks. And the simulating temperature stages of high-peak production of liquid hydrocarbons produced during the thermally simulating process of organic materials from different kinds of source rocks are also apparently different. So, it is important to pay attentions to the influence of source rock properties and organic material types while vitrinite reflectance taken as an index to divide lithogenetic stages and oil-gas forming stages.
