扰动

The main lithologic characteristic is that the rock types are dominated by light-colored clastic rocks reflecting the oxidation environment with a low maturity. The grain size distribution and sedimentary structure show that the rocks have the sedimentary characters of both gravity currents and tractional currents. Plant fragments are lacking and bioturbation structures are abundant and cyclic. Sandbodies are distributed in a ring shape.

其主要岩性特征为：岩石类型以反映氧化环境的浅色碎屑岩类为主，成熟度较低，粒度分布和沉积构造反映其兼有重力流和牵引流的沉积特点，植物碎屑贫乏而生物扰动构造丰富且具周期性，砂体呈环带状分布。
