Geosphere, October 2015, v. 11, p. 1343-1364, doi:10.1130/GES01121.1, Supplemental Figure S3 - Schematic representation of the uplift rates imposed for the various model scenarios tested, viewed in north-south orientation with respect to the Greater Caucasus. Black lines indicate initial geometries, grey lines indicate portion of the geometry that is different after initiation of second uplift zone. Concentric circle symbol indicates lateral propagation was implemented and dotted lines indicate the partial uplift rates implemented during these lateral propagation periods. Relative differences between the maximum value of the two uplift rates, U1 and U2 are given. Geometry of uplift rate gradient is labeled as either, “c” for a rate that decreases with the cube of distance, “s” for a rate that decreases with the square of distance, or “l” for a linear decrease with distance as described in the supplemental text. Below each uplift function is the output topography of the final time-step of the model. Final panel shows schematic of timesteps in the lateral propagation function. For this panel, the view is 90 degrees from the other diagrams, approximately east-west in terms of the Greater Caucasus. File size is ~43 MB.
