“…When a mechanism of formation is suggested, it is by reduction of a circulating fluid transporting soluble vanadium oxide coming into contact with a reducing agent, often another fluid or carbonaceous material (Wanty and Goldhaber 1992;Northrop and Goldhaber 1990;Schade et al 1986;Hostetler and Garrels 1962;Huff and Lesure 1962). Vanadium substitution in pre-existing micas has also been suggested (Parnell 1988).…”

Synopsis Roscoelite, a vanadium mica, occurs in the cores of reduction spots within the Lower Old Red Sandstone that crops out in Gamrie Bay (Moray Firth). The finely crystallized mineral is seen both as a cement in the sandstone and replacing plagioclase feldspar in a lithic clast of granitic composition. It is suggested that roscoelite was formed by a complex reaction involving a change in the oxidation–reduction potential of the groundwater and the presence in the sandstone of sensitive associations of minerals containing vanadium-rich iron and titanium oxides. The reduction spots formed by diffusion as part of the same process.

“…U raninite and pyrite, 'associated or not with oxidized products of these minerals, occupy the central part of the nodules, which generally are encased in a zone of manganese and iron oxides (Sharp and others, 1964). In the Montezuma Oanyon area, San Juan County, Utah, ellipsoidal bodies consist of cores of barren iron-stained sandstone as much as 10 feet thick •and 40 feet across, which are enclosed by shells of uranium-•and vanadium-bearing sandstone a few inches to a few feet thick; the surrounding host rock is barren gray sandstone (Huff and Lesure, 1962).…”

“…Geologic evidence for the operation of diffusion processes in forming uranium deposits in the Salt Wash Member is given by Huff and Lesure (1962) who describe the occurrence of ore layers in rolls which form complete shells around pockets of altered sandstone and fossil plant remains. Shawe (1956, p. 241) has interpreted the configurations of other roll structures as having formed at fixed interfaces between flowing ore solutions and cooler connate solutions.…”
