Geomorphic imprints of lithospheric flexure in central Australia
Earth and Planetary Science Letters（2022）
摘要
•We resolve the enigma of intertwined active and relict gorges in the Finke River.•Flexural response to cyclical tectonic loading imposes to-and-fro topographic tilting.•Loading variations may reflect mantle-flow tractions at the base of the plate.•Multi-million year storage of gorge gravels signifies the timescale of tilting.
