| 摘 要： | 泌阳断陷双河—赵凹地区下第三系核三上段所划三个陆相层序不仅在地震剖面、电测曲线上有显著的识别标志，而且它们在岩石地球化学特征上，亦有明显反映。具体地，识别陆相层序界面的岩石地球化学标志包括：①岩石类型标志；②砂砾岩中粘土矿物及胶结物特征；③化学成分标志；④碳氧同位素特征。

| Abstract: | The identification marking of three terrigenous sequences in the upper member of Eh of Biyang fault depression is distinct not only on seismic profile and electric log curve,but also in lithologic geochemical features.Particularly,the lithologic geochemical features to identify terrigenous sequence boundary include lithological types marking,clay mineral and cement characteristics in coarse fragments,chemical constituent,C and O isotope. |
