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(lèi)型的巖相組合。
Two or over two lithofacies make up three facies association including slope- submarine valley, submarine fan and basinal plain.
較大范圍內(nèi)兩個(gè)或兩個(gè)以上巖相組成斜坡—海底峽谷、海底扇、盆地平原三個(gè)相組合。
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.
認(rèn)為扎爾則油田泥盆系F4層的沉積相是海洋環(huán)境下重力流沉積形成的水下扇，從下到上為一海退—海進(jìn)沉積序列。
