Mémoire H.S. n°45 de Géologie AlpineIn well-Iogging, values of gamma-activity are measured by scintillometry. A conventional paradigm is to link high y-activity to Potassium (K) and Thorium (Th) isotopes present in clays and to Uranium isotopes present either in detrital sediments ( typically in zircon or monazite minerals) or to sediments rich in organic matter. In shallow-water carbonates platforms, high y-activities are interpreted in the same way. However, in a first y-scintillometer survey of the Gorges du Nan section (subalpine Vercors massif), we found inconsistencies between lithologies and their expected y-responses: the highest radioactive beds do not correspond to high argillaceous or detrital limestones and marls, but to some lo...
