Magnesia from Canadian Brucite
BRUCITE associated with highly metamorphosed Precambrian limestone was discovered in the vicinity of Rutherglen in northern Ontario by the writer during field work on the limestones of that district in 1937, and later was identified in similar limestone at Bryson and Wakefield, Quebec. The brucite occurs as granules disseminated through the limestone (Figure 1) and comprises from 20 to 35 per cent of the rock. Such rocks may be referred to as predazzites or pencatites, depending on the proportions of the constituent minerals.
