沉积

Iron oxides would continue to be formed or at least not to be dissolved under oxic conditions, and the sediments in brown to red color will then be dominant. While in a reducing environment, iron oxides will be dissolved, with the possible migration of iron ion in the ocean, and then buried as siderite, pyrite, or other ironbearing minerals.

There are three features in the minibasins induced by gravitational sliding on the slope: the firstly, feature is surface of unconformity developed by onlap on minibasin margins or surface of unconformity truncated by mass transport-complex are sequence boundary in the study area; the secondly , accommodation of gravity flow is controlled by up lift rate and sedimentation rate , and styles of filling in the minibasins are dominated by the interrelationship between the two factors; and the third , there are two stacking patterns that consists of upward of turbidite fan-hemipelagic drape mud or mass-transport complexes-turbidite fan-hemipelagic drape mud.

认为在深水陆坡重力滑动作用所形成的微盆地内，层序边界表现为微盆地边缘上超不整合面或重力流对下伏地层的侵蚀不整合；逆冲构造隆升速率与沉积速率共同控制了重力流可容空间和沉积充填样式；沉积垂向演化以块状搬运复合体一浊积扇－深海披覆泥或浊积扇－深海披覆泥为特征。
