- •
We date paleoshorelines in Chile between 24°S and 32°S using 10Be concentrations data.
- •
Post-emergence erosion of abrasion shore terraces approaches 1 m/Myr.
- •
The coast has been uplifting at ~ 0.3 mm/yr during the Upper Pleistocene.
- •
Uplift velocity increased during the Pleistocene following a period of stability.
- •
Paleoshorelines are poorly preserved beneath the northern coastal scarp.
