Tropical weathering in Norway, TWIN final report

Abstract

The Geological Survey of Norway and the Norwegian Petroleum Directorate established the TWIN Project (Tropical Weathering In Norway) in 2009 to improve the understanding of deep weathering on mainland Norway as well as offshore. All known reports of deep weathering in Norway have been reviewed and registered in a GIS database. We have selected four representative locations for more detailed studies in southern Norway (Kjose, Lista, Vågsøy-Stad and Inderøy) and another four locations in northern Norway (Vestvågøy, Hadseløya, Andøya and Hamarøy).
