submarine fan

基本解释

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。
Two or over two lithofacies make up three facies association including slope- submarine valley, submarine fan and basinal plain.
较大范围内两个或两个以上岩相组成斜坡—海底峡谷、海底扇、盆地平原三个相组合。
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。
