Geology

Province: Paleozoic and Mesozoic Basins

Subprovince: Moose River Basin



Geology Comments

Dec 07, 2005 (D Draper) - Gypsum occurrences of the Moose River Basin are considered part of the lower Middle Devonian Moose River Formation. (GSC MEM 379, p.90). The exposures here rise approximately 2m above the water and occurs primarily along the east bank of the river for a distance of one kilometre. (AR 13, p.158; IMR 18, p.63; IMBP 12, p.15) Dyer describes the gypsum as being overlain by limestone with [Q] grey fossiliferous limestone of the Abitibi River formation in close proximity. (AR Vol 37-6, p.43).

Lithology Comments

Dec 07, 2005 (D Draper) - [Q]: The quality of the gypsum is high, uniformly fine-grained, white, and massive. Impurities consist of rare brown and black limy laminae and traces of rusty sulphide stain. Minor amounts of clear grey selenite are disseminated through the massive gypsum in stallate recrystallized spots. No limestone or gypsum breccia observed. (IMR 18, p.63).

Mineralization Comments

Dec 07, 2005 (D Draper) - Exposure consists of both greyish and whitish crystalline gypsum intermixed with streaks of pure selenite. (AR 13, p. 158) Ont. Dept. of Mines analyzed chip samples taken at random over outcrop area (1964); these returned a value of 95.60% gypsum. (IMR 18, p.64).
