Abstract
Uranium-series nuclides are responsible for the gamma -ray anomalies associated with iron veins in Israel; Th and K contributions are negligible. The U content in hand samples is as high as 2000 ppm. Uranium, like a variety of other trace elements encountered, is disseminated within the Fe phases and does not form independent minerals even at high concentrations. The richest U content is found in hematite. Goethite, derived from the alteration of hematite, contains less U, but still considerably more than the U-poor marine carbonate host rocks, generally of Cretaceous age.-from Authors
