Figure 3—Bedrock weathering, erosion, and tor development.
Weathering rate, W(h) [m/m.y.], as a function of sediment thickness, h [m]. Dashed lines represent rate at which alluvial surface is lowering (erosion rates, labeled e and e’ [m/m.y.]). The hatched region represents the range of alluvial surface erosion rates that permit tor development as described in the text, and extends from the peak of the weathering curve down to the bare-bedrock weathering rate of 14 m/m.y.
