人们常常根据沉积物所含不溶有机质（干酪根）的碳同位素比值来推断源岩一油的相互关系，因为每种干酪根都有受显微组分组成控制的特定值。本研究的目的是为了表征从各种干酪根中分离出来的每种显微组分的δ13C值，并检验每种显微组分是否都有特定值。首先，利用比重分离法从绿
The relationship between source rock and oil is often inferred from the carbon isotope ratio of insoluble organic matter (kerogen) in sediments because each kerogen has a specific value that is controlled by the composition of the micro-components. The purpose of this study was to characterize the δ13C values for each of the micro-components isolated from various kerogen and to verify that each of the micro-components has a specific value. First, the use of gravity separation from the green
