Name:In allusion to the satiny luster and its original identity as a spar mineral.


A fibrous variety of Gypsum or Calcite and Aragonite.

The name originally referred to a variety of Calcite found in "Cumberland, England", but the name was eventually used to cover varieties of Aragonite and Gypsum too, so this name is best used as an adjective in conjunction with a mineral name rather than as a specific variety name of its own - see Satin Spar Gypsum and Satin Spar Calcite.
