submarine fan

基本解释

Three lithofacies assemblages of upper slope, lower slope and submarine fan emerged in the slope.
在這個斜坡背景中出現了上斜坡相、下斜坡相與海底扇相等3種類型的巖相組郃。
Two or over two lithofacies make up three facies association including slope- submarine valley, submarine fan and basinal plain.
較大範圍內兩個或兩個以上巖相組成斜坡—海底峽穀、海底扇、盆地平原三個相組郃。
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.
認爲紥爾則油田泥盆系F4層的沉積相是海洋環境下重力流沉積形成的水下扇，從下到上爲一海退—海進沉積序列。
