Each unitis of different biotic characters and displays different features of seawater composition during the time. 2 The black unit including a biotic extinction was caused by oceanic anoxic event. Crisis that deepwater keeled foraminifera encountered represents a ferocious anoxia in deep marine environment . Biotic recovery in gray unit reflects gradually improved marine circumstance. What the biotic extinction at the C/T boundary in black unit reflects an environmental mutation, whereas the gradual biotic change characterize the recovery of marine dissolved oxygen environment in a stepwise process. The red unit is the result of oxic deposition and characterized by extremely abundance of foraminiferal faunas, which reflects a high-oxidized marine circumstance. 3 As the most ordinary biotic index in paleoceanography researches, foraminifera represent anexcellent environmental indicator in this paper.

三套岩层表现出不同的生物特征，并指示出当时海水的不同性质。2黑层段是大洋缺氧造成的结果，生物大量灭绝，深层水具旋脊有孔虫的所遭受的危机反映出当时海洋深层水体严重缺氧的特征；灰层段中生物的恢复反映出海洋环境自缺氧事件之后的逐步改善过程，与黑层段反映的C/T 界线处生物绝灭反映的环境突变不同，灰层段生物特征的渐变指示出当时海洋溶解氧环境的恢复也是一个逐步的过程；红层段属于富氧沉积的产物，特征是有孔虫生物的极度繁盛，反映的是一种高氧化性的海洋环境。3有孔虫作为古海洋研究中最常用的生物指标，在本文研究中显示了良好的环境指示性。
