Keywords: Uranium, thorium, mineral evolution, ore deposits, geobiology. A comprehensive survey of the uraninite and coffinite assemblage of the Chenjiazhuang, Xiaohuacha, and Guangshigou biotite pegmatites in this uraniferous province reveal the primary magmatic U mineralization and its response during subsequent hydrothermal events

Metamorphosed volcanogenic uranium deposits are briefly treated here, even though some . Thorium concentrations during this stage exceed uranium

Metamorphosed volcanogenic uranium deposits are briefly treated here, even though some (Gandhi, 1978; Curtis, 1981) recognize syn-volcanic features in metamorphic terrains of northern and eastern Canada (for example, Baker Lake Basin and Makkovik Fold Belt). Thorium concentrations during this stage exceed uranium. The deposits contain a variety of yellow, hexavalent U minerals, but some uraninite is found at Nopal I. Studies by Goodell (1981a) and his students found a trace element suite similar to epithermal ore deposits but inconsistent associations with U. They propose that uranium was leached from volcanic glass by heated groundwaters.

The Ontario Geological Survey (OGS) is an administrative Branch of the Ontario Ministry of Energy, Northern Development and Mines. OGS helps people understand how to apply the geological knowledge about Ontario to address a range of public policy issues.

Deposits around the Bancroft, Ontario, area were discovered by the early 1950s, and the first discovery in Ontario's Elliot Lake region was in 1953. The northern Saskatchewan uranium province was also discovered in the 1950s and Eldorado Nuclear began mining at Beaverlodge in 1953. By 1956 thousands of radioactive occurrences had been discovered.

Part One describes the minerals and mineral deposits that are the sources and potential sources of uranium, thorium and beryllium, with full attention to physical properties and geologic characteristics, together with a careful description of the identifying marks of likely deposits. Among other things, radioactivity from supposed deposits of uranium was blamed for making cows lose their hair, stopping watches, and for causing burns, fires, and a ringing in the ears.
