The simulation thickness gradually increases from the top of the alluvial fan
to the central basin, and the maximum simulation thickness is 1800 m.
In this area the fault controls a conspicuous relief front that shows a hard calcrete-crust developed over Pleistocene alluvial fan
deposits dipping towards northwest.
Surficial patterns of debris flow deposition on alluvial fans
in Death Valley, CA using airborne laser swath mapping Geomorphology, v.74, p.152-163, 2006.
The drill hole encountered slightly compact but poorly consolidated Holocene and Pleistocene greenish grey gravelly sand (alluvial fan
deposits to 2 meters with a Vs equal to 185 m/s).
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.
The rounded shape of some stones in the conglomerate indicates long-distance transport from above the rim, where a channel named Peace Vallis feeds into the alluvial fan
. The abundance of channels in the fan between the rim and conglomerate suggests flows continued or repeated over a long time, not just once or for a few years.
The rocks in the outcrops were formed when water transported gravels downslope to bottom of alluvial fan
, where they remained for some time.
--The resulted gully erosion organisms and the processes of creeping form numerous alluvial fans
in our surveyed areas;
indicate the existence of complex processes of change in the landscape of the Pantanal, resulting from the sedimentary dynamic in alluvial fans
. In these fan regions the landscape changes continuously because of sedimentation and by avulsion processes.
