An article by Ghosh et al. in this month’s Science magazine describes a new stable isotope technique to derive paleoaltimetry data that indicate extremely rapid uplift of a region of the Bolivian Andes. They hypothesize that the data might be explained by detachment of the dense lithospheric root of the mountain belt, as previously demonstrated in the Sierra Nevada range in California.

You might want to link to the article by Ghosh et al. here, too - Ghosh et al. did the actual paleoaltimetry, Poage and Chamberlain just wrote the “perspectives” article accompanying it.

Thank you for catching this Yami. That’s what I get for posting secondhand news without checking the original sources. I hope I’ve corrected it now. Glad to see you’re keeping me honest!
