Alluvial cone
| Глоссарий геологических терминов |
A semi-conical type of alluvial fan with very steep slopes; it is higher, narrower, and steeper (e.g., > 40% slopes) than a fan, and composed of coarser, and thicker layers of material deposited by a combination of alluvial episodes and to a much lesser degree, landslides (e.g., debris flow). coarsest materials tend to concentrate at the cone apex. compare - alluvial fan, talus cone. sw

Alluvial fan, английский
- A low, outspread mass of loose materials and/or rock material, commonly with gentle slopes, shaped like an open fan or a segment of a cone, deposited by a stream (best expressed in semiarid regions) at the place where it issues from a narrow mountain or upland valley; or where a tributary stream is near or at its junction with the main stream. it is steepest near its apex which points upstream and slopes gently and convexly outward (downstream) with a gradual decrease in gradient. gg
- A large, sloping sedimentary deposit at the mouth of a canyon, laid down by intermittently flowing water, especially in arid climates, and composed of gravel and sand. the deposit tends to be coarse and unworked, with angular, poorly sorted grains in thin, overlapping sheets. a line of fans may eventually coalesce into an apron that grows broader and higher as the slopes above are eroded away.
