Within the walls of Acopios 1 and Acopios 2 a high angle (subvertical), south-dipping fault zone affecting
alluvial fan deposits can be seen (Figs.
The Urao lake shows a transition from the
alluvial fan deposits in the northern margin of the basin towards the fine clay deposits of the lake centre.
When we look at the location of the Curiosity landing site with respect to the
alluvial fan we can see that the rover landed downstream of the 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).
Accumulation processes have a lower manifestation, especially, in creeks confluence area with the Valsan river mouth and its tributaries valleys as
alluvial fan.
Geomorphologic relations hips and ages of soils on
alluvial fans in the rio General valley, Costa Rica.
It features a depositional tract of sandy sediments derived from the plateaus of sedimentary basins, forming huge
alluvial fans and lacustrine and fluvial environments.
The
alluvial fans and hillsides had some difficulties for crop production, because the streams can sweep the soil instead of depositing it; furthermore, the streams can change their course over the
alluvial fan from one year to another.
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).
The gentle
alluvial fan of the Preak Tnaot was also generally not inundated, except for its low-lying eastern skirt (within Phnom Penh city).
Alluvial fans develop where the stream trunk enters the "Delta" as these streams lose their energy and their bed load.
Two research groups of the Geological Society of London claim that they chose Sorbas, in southeastern Spain as the cite for 2003 a conference on
alluvial fans because it is a tectonically active dry region with a wide range of Quaternary
alluvial fans.
