Gypsum is important in building industry; output in 1926 was 5,635, 411 tons, including 200,000 tons of anhydrite; many important gypsum deposits were originally anhydrite; general notes of occurrences in Nova Scotia, New Brunswick, Newfoundland and Prince Edward Island, in Canada; at least half of gypsum deposits in United States are associated with anhydrite; latter lacks water of crystallization and cannot be changed to hemi-hydrate by calcination.
