Three lithofacies assemblages of upper slope, lower slope and submarine fan emerged in the slope.

在这个斜坡背景中出现了上斜坡相、下斜坡相与 海底 扇相等3种类型的岩相组合。

It is considered that F4 layer is a submarine fan generated by gravity flow in marine environment, with a regressive-transgressive sequence from the lower to the upper parts.

认为扎尔则油田泥盆系F4层的沉积相是海洋环境下重力流沉积形成的水下扇，从下到上为一海退—海进沉积序列。

Upward-fining channels may occur in a wide range of environments from submarine canyon to alluvial fan.

向上变细的水道可以出现在好多种环境中，从海底峡谷到冲积扇。
