摘要
本文提出了宜昌奥陶系沉积相是台地相—台地边缘相—浅海盆地相的多相台棚式的组合类型,指出奥陶系经历了四次海进到海退的沉积旋回过程。
In this paper, it is suggested that the Ordovician sedimentary facies in the Yichang region are a combination type consisting of platform facies, platform margin facies and shallow sea basin facies. This region had had four sedimentary cycles associated with transgressions and regressions at the Ordovician period
