      The proposed CRP will look into complete geochemical and mineralogical characterization of uranium and thorium deposits, including production of high precision data on major, minor and trace elements; stable and radioactive isotopes; identification of major uranium, thorium and other ore minerals; and fluid inclusion studies.   Uranium (U), vanadium (V), molybdenum (Mb), sulfur (S) and organic carbon (Corg) in selected samples from deep drill cores in the Storsjö area. Data according to Snäll (). In Skåne, both U and V have been analyzed continuously along drill cores and thus provide a means to clearly differentiating zones with high and low values in the Alum.
