The Beaverlodge area is within, and near the western border of, the Canadian Shield. It is dissected into ridges trending northeasterly. Relief is generally less than 100 m. The oldest rocks, possibly Archaean, are called the Tazin group. They were once sediments, but now they are mainly rocks granitized to banded gneisses and granites. Locally, they are quartzite, dolomite, argillite, quartz-biotite schist, garnetiferous gneiss, amphibolite, and chlorite- epidote rocks. Folds in the Tazin rocks are open, tight, isoclinal, and locally complex. Uranium deposits are pegmatitic and hydrothermal. Pegmatitic deposits are in Tazin rocks only, but none has proved economic. Hydrothermal deposits occur in both the Tazin and Athabasca rocks, but almost all production is from ore bodies in the Tazin. They are of the disseminated type and the vein type. The probable formation of the deposits is given. The most favorable rocks affecting deposition of pitchblende appear to have been siliceous argillite or related mixtures. The geology and structure of the main mining properties are described specifically. (auth)
