Sep 08, 2016 (A Wilson) - These samples are part of a wide northwest-trending metasedimentary-marble belt which is several kilometres in length. Flanking the marble portion of the belt is metasedimentary hornblende amphibolite paragneiss and paragneiss-marble migmatite. The marble is white to light grey and is dolomitic to calcitic in composition. Marble in this area can be subdivided into two categories: a) white with minor impurities; and b) grey with minor impurities. Only one marble outcrop that would be considered impure occurs in the map area. White marble has a grain size of up to 3 mm and contains only minor amounts of graphite, pyrite, and phlogopite. Grey marble has a grain size of up to 8 mm and contains minor graphite and muscovite. Minor occurrences of dolomitic marble appear throughout the belt but cannot be traced over any distance. The marble unit terminates to the east with a paragneiss unit, which in turn is bounded by a metamorphosed granitic intrusion to the east.
Sep 08, 2016 (A Wilson) - Map area 1912 has both white and light grey marble with only minor impurities occurring over a large area. It is possible that further investigation across strike would show an even larger amount of white marble. Up to 20 percent tremolite occurs in some outcrops and may be of interest as a by-product of marble extraction.
