牙形石

通过对同一岩样进行Ro%的测定及牙形石颜色观察，得出CAI值与镜煤反射率（Ro%）的规律性关系，证明CAI值作为有机质成熟度的指标之一是可行的。

From determination of Ro % and colour observation of conodonts of a same rock sample , the relationship between CAI value and Ro % of vitrites is derived , which indicates that the CAI value may be used as one of the indices of maturity of organic matter .
