We've got a new paper out that uses U-Pb and U-Th/He ages on the same zircon grains (aka 'double dating') from Amazon submarine fan sediments to investigate cycles of mountain building in the Andes.

The lead author of the study, Cody Mason, and I wrote this blog post on the publisher's site to explain in detail: https://earthenvironmentcommunity.nature.com/posts/cycles-of-andean-mountain-building-archived-in-the-amazon-fan

This is a paper that started before COVID, got de-prioritized, and then recently revived!
