Uranium exploration geologic

Abstract strong commodity prices in the last few years have led to a remarkable renaissance of uranium exploration in Labrador, focused in a complex and geologically diverse region known as the Central Mineral Belt (CMB). Potentially economic epigenetic U deposits are mostly hosted by supracrustal rocks of Paleoproterozoic and Mesoproterozoic age, and are difficult to place in the traditional pantheon of uranium deposit types. Recent exploration work implies that structural controls are important in some examples, but the relationships between mineralization and deformation remain far from clear. Geochronological data imply at least three periods of uranium mineralization between 1900 and 1650 Ma. It seems likely that the Labrador CMB represents a region in which U (and other lithophile elements) were repeatedly and sequentially concentrated by hydrothermal processes. The current exploration boom lends impetus for systematic research studies that may ultimately lead to refined genetic models that may be applicable elsewhere.

There is such a large number of comparison studies and case histories in the literature that it is virtually impossible to cite them all. Many of them have already been referred to in the foregoing sections, fanner (1964b, 1978) described a number of case histories and comparison studies involving soil-gas radon. Adkinson and Reimer (1976) prepared a bibliography of references of geological interest to uranium exploration.

Further exploration and higher prices will certainly, on the basis of present geological knowledge, yield further resources as present ones are consumed. There was very little uranium exploration between 1985 and 2005, so the significant increase in exploration effort that has got underway since then will probably substantially increase the known economic resources.
