The pyritebearing Eagle Ford shale contains gypsum (CaSO 4 • 2H 2 O) produced by reaction of calcium carbonate in the shale with acid sulfate from oxidation weathering of pyrite (FeS 2). Sulfate movement upward in the soils can occur by capillarity, and it can be carried downward by infiltration, an often incomplete or interrupted event that leaves gypsum stranded as a soil evaporite. Once ...

 · The deterioration of buildings and monuments by gypsum is the result of crystallization cycles of this salt. Although gypsum can dehydrate to a hemihydrate, the mineral bassanite, and to an anhydrate, the mineral anhydrite, this reaction occurs in nature on a geological time scale and therefore it is unlikely to occur when gypsum is found on and in building materials. The CaSO4–H2O system ...
