A unique depositional sequence consists of phylloid algal buildups, bioclastic Banks and mud facies affected by frequent changes of depositional environments.
叶状藻礁在沉积环境频繁变化作用下,与碎屑滩相、灰泥相共同形成独特的沉积序列。
It can be used to determine boundaries of depositional sequence and system tracts, current direction, hydraulic energy and manifold depositional environments.
用它可以确定层序和体系域边界,判断水流方向和水动力大小,识别多种沉积环境。
Some rock type characteristics of the depositional sequence in the seismic event are summarily described, and the origin of the seismic depositional rock is preliminarily studied in this paper.
