  2. Alluvial fan - Wikipedia

    en.wikipedia.org/wiki/Alluvial_fan

    Alluvial fans are common in the geologic record, such as in the Triassic basins of eastern North America and the New Red Sandstone of south Devon. Such fan deposits likely contain the largest accumulations of gravel in the geologic record. Alluvial fans have also been found on Mars and Titan, showing that fluvial processes have occurred on ...

  3. Tectonic influences on alluvial fans - Wikipedia

    en.wikipedia.org/wiki/Tectonic_influences_on...

    The shape of alluvial fans is mostly influenced tectonically. An alluvial fan can be completely changed due to orogenic thrusting. [4] An alluvial fan could have been deposited and formed outside of a mountain range, however, thrusting of the mountain belt could cause the alluvial fan to become broken up by the new mountain forming.

    Alluvial fanFan-shaped deposit of sediment; Anabranch – A section of a river or stream that diverts from the main channel and rejoins it downstream. Arroyo – Dry watercourse with flow after rain; Asymmetric valley – Valley that has steeper slopes on one side; Backswamp – Environment on a floodplain where deposits settle after a flood

  6. Bajada (geography) - Wikipedia

    en.wikipedia.org/wiki/Bajada_(geography)

    These fan-shaped deposits form by the deposition of sediment within a stream onto flat land at the base of a mountain. [1] The usage of the term in landscape description or geomorphology derives from the Spanish word bajada , generally having the sense of "descent" or "inclination".

  7. Conglomerate (geology) - Wikipedia

    en.wikipedia.org/wiki/Conglomerate_(geology)

    Fanglomerates are poorly sorted, matrix-rich conglomerates that originated as debris flows on alluvial fans and likely contain the largest accumulations of gravel in the geologic record. [4] Breccias are similar to conglomerates, but have clasts that have angular (rather than rounded) shapes.

  9. River delta - Wikipedia

    en.wikipedia.org/wiki/River_delta

    Alluvial fan deltas, as seen by their name, avulse frequently and more closely approximate an ideal fan shape. Most large river deltas discharge to intra-cratonic basins on the trailing edges of passive margins due to the majority of large rivers such as the Mississippi , Nile , Amazon , Ganges , Indus , Yangtze , and Yellow River discharging ...
