Short summary
We proposed a new non-destructive mineralogical methodology on sub-millimeter grains that allows us to quantify the hematite and goethite content and hematite / goethite ratio of grains prior to (U–Th) / He geochronological analysis. (U–Th) / He data performed on different aliquots with different acquisition times show no remarkable differences in age, opening a new way to investigate the (U–Th) / He data evolution in supergene lateritic duricrusts.
