My GFZ collaborator Laura V. Krone just published her first paper from her PhD as part of the EarthShape project. From the drilling campaign in the semi-arid study site in Santa Gracia in Chile, we found multiple weathering fronts at various depths, even reaching as deep as 76 m from the surface. The denudation rate from this site result in a slow turnover time of the entire weathering zone (~7 million years). Despite this, we show that deep weathering is still possible.
