Autor: Nicolaj K. Larsen, Kristian B.R. Kristensen, Marie-Louise Siggaard-Andersen, Claus Heilmann-Clausen, Kurt H. Kjær

Publikováno v: GEUS Bulletin, Vol 53, Pp 1-7 (2023)

In this study, we test if cost-efficient X-ray fluorescence (XRF) analyses can be used to fingerprint Palaeogene clay and marl deposits in Denmark. A total of 67 samples from key sites in Denmark have been analysed. Our preliminary results indicate t
