A deposit formed by a debris flow.
感觉是碎石流沉积。以下是debris flow 的解释。从一个网站copy来的。
debris flow Slow-moving, sediment gravity flow composed of large clasts supported and carried by a mud-water mixture. Debris flows occur as overland and submarine mudflows, and as submarine deep-sea deposits. The deposits are poorly sorted and internally structureless; typically they have a pebbly, mudstone texture. Debris-flow deposits cover many thousands of square kilometres of the abyssal plain after originating on the continental slope as slumped material. |
