海底峡谷

海底峡谷，是由于地壳板块运动而形成的一种地质构造。

Submarine canyon is a geological structure that formed by plate movement in the crust .

海底峡谷成因新探

On the genesis of Submarine Canyon

由此可见塌向刚果海底峡谷的泥沙量之大，这条蜿蜒的通道从非洲西部海岸线切入海洋。

This gives you a sense of the volume of sand and mud that collapsed3 down the Congo Canyon4 – a sinuous5 channel that leads away from the West African coastline .

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。

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

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。

Two or over two lithofacies make up three facies association including slope - submarine valley , submarine fan and basinal plain .

构成低位体系域的沉积体系主要有盆底扇、斜坡扇、前积楔、三角洲、扇三角洲、冲积扇、海底峡谷和下切谷等。

The sedimentary systems of lowstand system tracts include basin floor fan , slope fan , progradational wedge , delta , fan delta , alluvial fan , submarine valley and incised valley .

细颗粒沉积物向深海的输运受到两种作用的控制：在狭窄的陆架，重力作用形成沿着海底峡谷向深海运动的浊流；

The escape of fine-grained material from the shelves is controlled by two mechanisms : on narrow shelves , transport may be due to turbid currents driven by gravity in submarine canyons ;

高水位体系域，主要分布在三角洲、扇三角洲、海底扇和峡谷水道。

In a lowstand systems tract , sandstones are mainly distributed in lowstand wedges , slope fans , basin-floor fans , fan deltas , deltas and submarine canyons ;
