Seeking indicators of tills weathering: how can we exploit geophysical and geochemical methods?

Abstract

(1) major and trace elements content analysis using ICP-MS (Inductively Coupled Plasma – Mass Spectrometry) and XRF Fluorescence), (2) geophysical logging of till profiles with handheld gamma-ray spectrometry (GRS) yields the concentrations of K, Th, U and total gamma-ray signal (GR), (3) correlation of weathering indices obtained by geochemical analyses with geophysical logging results.
