views updated May 08 2018

calcrete uranium In arid climates prolonged evaporation may cause hard surface crusts to form; if CaCO3 predominates the crust is called caliche (calcrete). Where the bedrock contains high levels of uranium the calcrete is locally uraniferous and may constitute a workable ore, e.g. in western Australia and Namibia.
