Here is a new publication by Jiao about the work he did on the Southern Alps of New Zealand. Jiao used on Raman Spectroscopy of Carbonaceous Material on sediments. The study shows how erosion patterns vary during a glacial retreat. Jiao’s new work extends nicely the work we published in the last few years using the same methodology (Herman et al., 2015; Nibourel et al., 2015; Beyssac et al., 2016).
