摘要
泌阳断陷双河赵凹地区下第三系核三上段包括三个陆相层序，它们在岩石类型、矿物成分、化学成分及Ｃ、Ｏ同位素特征等方面，均呈现旋回性变化规律。据此，亦可作为划分和识别陆相层序的依据之一。
The upper member of Eh3 consists of three terrigenous sequences for Shuanghe Zh aoao area, Biyang fault depression, and the sequences show cyclical changes and differential characteristics in lithological features, mineral compositions, che mical constituents and C and O isotopes. The lithologic geochemical cyclicity l aw can be used as one of evidences to divide and identify terrigenous sequences.
