The 27 pages that link to Gypsum, each with the reason it gives.

• Calcium carbonateCompared with: It is another common calcium mineral, but contains sulfate rather than carbonate.

• CalciteCompared with: It can resemble pale calcite but is much softer and does not effervesce with dilute acid.

• Mohs scaleBroader topic: It is the next standard mineral above talc.

• EvaporiteBroader topic: Gypsum commonly precipitates early in the sequence of evaporite minerals.

• SulfateBroader topic: It is a widespread sulfate mineral used in plaster and drywall.

• HydrateBroader topic: Heating gypsum partially removes its crystal water to produce plaster of Paris.

• Phosphoric acidRelated: The wet-process reaction commonly precipitates gypsum as a large-volume byproduct.

• CalcinationRelated: Heating gypsum removes bound water, a widely used calcination process.

• Monoclinic crystal systemBroader topic: Gypsum is a familiar mineral that crystallizes in the monoclinic system.

• Portland cementRelated: Added during grinding, it controls the rapid reaction of clinker aluminates with water.

• SpeleogenesisRelated: Groundwater dissolves gypsum readily, allowing caves to develop faster than in limestone.

• CementRelated: It moderates rapid reactions of clinker aluminates and helps regulate setting.

• Crystal waterBroader topic: Its crystal water distinguishes gypsum from anhydrous calcium sulfate.

• Flue-gas desulfurizationRelated: Forced oxidation of captured sulfur produces gypsum that can be recovered from wet systems.

• Messinian salinity crisisBroader topic: Gypsum beds record an early stage of evaporative concentration in the basin.

• Soil amendmentRelated: Can supply calcium and help reclaim some sodic soils without substantially raising pH.

• GessoRelated: Gypsum-based grounds rely on this mineral instead of chalk.

• Calcium sulfateBroader topic: This hydrated mineral is calcium sulfate’s most familiar natural form and the source of plaster.

• Carlsbad CavernsRelated: Gypsum deposits in the cave preserve evidence of sulfuric-acid dissolution.

• Lechuguilla CaveRelated: Gypsum occurs in striking formations created by sulfuric-acid reactions in the cave.

• AnhydriteCompared with: Gypsum is anhydrite's hydrated counterpart and is softer and less dense.

• Sulfate mineralBroader topic: Gypsum is a common hydrated sulfate and a major component of evaporite deposits.

• White Sands National ParkNarrower topic: The dunes are made of gypsum crystals rather than the quartz sand common in most deserts.

• Axel Heiberg IslandRelated: Gypsum occurs with evaporite deposits that help characterize the island’s unusual salt geology.

• Optymistychna CaveRelated: The cave’s walls and passages formed in this soluble mineral.

• Frasassi CavesRelated: Sulfuric-acid reactions with limestone can leave gypsum deposits in the caves.

• Solutional caveRelated: Gypsum dissolves more readily than limestone, allowing caves to form rapidly in suitable settings.
