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).
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
