Mica Group

This page is currently not sponsored. Click here to sponsor this page.



Name:Probably used in the mineralogical sense by 1706 and originally "smicka" and from the Latin micare - to flash or glisten in allusion to the material's appearance. Isinglass predates the use of mica as a mineral term and known from at least 1535, but isinglass also referred to the matter from the sturgeon fish that also had pearly flakes from the scales.


A group of sheet silicates that can be parted into flexible or brittle sheets. Includes the True Micas and the Brittle Micas. Also known as the "mica family."
