Want to know why some mountain ranges have steep fronts whilst others have gentle gradients? Check out my new paper with @AlexCopley_ in @AGU_GCubed. Summary below (1/5)

We combined results from oxygen isotope palaeoaltimetry in south east Tibet with numerical models to investigate the effect of lateral contrasts in the strength of the lower crust on the development of mountain ranges.
Key findings:
1. Lateral variations in lower crustal strength provide a first-order control on the shape and temporal evolution of mountain ranges
2. Strong lower crust in the Sichuan Basin can explain the development of topography in the Longmen Shan without #channelflow

3. Lateral transport of samples should be considered in interpreting palaeoelevations from stable-isotope palaeoaltimetry
(but #geochemistry results should be included in #geodynamic models!)

Enjoy! and if you can't access the paper, the accepted manuscript is on @EarthArXiv doi.org/10.31223/osf.i…
