Fibrous Minerals in the Wabush Iron Ore District, Labrador, Newfoundland Canada
Fibrous minerals are common in the highgrade, metamorphic, Precambrian Wabush Iron Formation, Labrador, Newfoundland, Canada. The most abundant fibres are amphiboles of the cummingtonite-grunerite series; mineralogical studies support the work of Klein (1960, 1964, 1966) and Chakraborty (1966). Iron...
