STATUS REPORT FROM SWEDEN
DESCRIPTION OF SWEDEN'S LOW -GRADE URANIUM DEPOSITS. (Page 43)
Excerpt:
”The most important and well-known uranium deposits are those in the alum shales. Uranium content reaching 100 g/t ore more is found in the strata beginning with the Olenus in the upper Cambrian and ending with the Dictyonema and the Ceratopyge in the region between Cambrian and Ordovician. The Olenus shale is regionally distributed into nearly all CambroSilurian districts in Sweden, i. e.' in the provinces of Scania, Oland, Vastergotland, Narke and Norrland.”
