It is found in Norway in considerable quantity, especially in the neighborhood of Arendal. As found it always contains water, but the original mineral was doubtless anhydrous, and isomorphous with zirconium, silicate, or zircon. Some varieties of the mineral, called uranothorite, contain a considerable amount of uranium.
