submarine fan

基本解釋

Three lithofacies assemblages of upper slope, lower slope and submarine fan emerged in the slope.
在這個(gè)斜坡背景中出現(xiàn)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(fàn)圍內(nèi)兩個(gè)或兩個(gè)以上巖相組成斜坡—海底峽穀、海底扇、盆地平原三個(gè)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(rèn)爲(wèi)紥爾則油田泥盆系F4層的沉積相是海洋環(huán)境下重力流沉積形成的水下扇，從下到上爲(wèi)一海退—海進(jìn)沉積序列。
