1. Fault block uplift and subsidence
This movie shows a simulation of a pair of normal-fault blocks separated by
a vertical fault. The lower left edge is fixed through time, and represents
a shallow shelf just below sea level. The inner block of the landscape rises
at a steady rate, while the outer block subsides. Initially, the relief and
erosion rate are small, and the subsiding basin is underfilled. Notice the
progradation of a fan-delta complex. As relief and sediment flux increase, the
fan deltas reach the shallow shelf and the basin becomes filled (or
"over-filled" as they say, meaning that there is more than enough sediment
to keep filling the basin as it continues to subside).
2. Evolution of river valley landscape, stratigraphy, and geoarchaeology
These animations show three valley evolution scenarios discussed by
Clevis
et al. (2006). Animations created by Quintijn Clevis.
