The age of alluvial fan
deposition at a site in the Southern Uplands of Scotland, Earth Surfaces Processes and Landforms 19: 333-48.
In Holocene time, regional uplift, or movement along the Cerro Bola fault, possibly in addition to climatic change, caused dissection of the older pediment and alluvial fans, and creation of new, younger alluvial fans and a new, younger pediment surface at a lower level.
Previous episodes of such regrading is implied by the remnants of an older pediment surface and alluvial fans preserved around Cerro San Ignacio.
Seven plenary meetings are planned in communities most affected by rapid growth on alluvial fans
as projected by local governments through 2030.
Nevertheless, alluvial fans
were not subsequently ignored.
If we look more broadly in Gale Crater, we can see that there is a prominent feature that geologists call an alluvial fan
Three alluvial fans
within the plain; namely: the Zarub fan in the north, the Moundassah fan in the middle and the Ajran fan in the south (Al-Shamsei, 1993).
Most significant is that all strata in the two successions were deposited in continental environments-mainly fluvial and alluvial fan
settings (Nadon 1981; Nadon and Middleton 1985).
In the view to the north, erosion has produced subtle shadings of red and gray, with cream-colored accents spreading out in alluvial fans
With a little patience, though, during the late fall, winter, and especially spring, spectacular wildflowers may grace the alluvial fans
and desert slopes along the Amargosa and Panamint ranges.
Most of the localised recharge happens during summer storms, where ephemeral creeks lose part of their water in the alluvial fans
The early stretches of this 6-mile round-trip walk provide more of an introduction to the rocky complexity of alluvial fans
than you might like.
