The Settlers at Home He stood motionless, staring at the road where the heat waves shimmered, his absent gaze following a miniature cyclone that picked up and whirled a little cloud of powdered gypsum, while Helene waited. The Dude Wrangler The hydration of anhydrite to form gypsum, on the other hand, involves an increase of volume and may result in the doming up and shattering of the overlying sediments. The Economic Aspect of Geology It is possible that gypsum may act as an oxidising agent in the soil, just as iron in the ferric condition does.
