| Abstract: | To investigate the correlation between the inorganic elements and the abnormal vitrinite reflectance(Ro),the Third Member of Shahejie Formation is closely surveyed and analyzed.The results shows that the contents of K,Na,Zn,Ni,Mg,Li,Ba,Co and Rb have positive correlation with the value of Ro in the whole,and the strong alkali metals including K,Na and Rb show high positive correlation.The contents of Ca,Sr and Mn have negative correlation with the value of Ro in the whole.And the contents of Fe and B have no correlation with the value of Ro for its little variety. |
