About Mica GroupHide

As a Commodity:
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."

Age distributionHide

Recorded ages:
Paleoproterozoic to Quaternary : 1880 ± 16 Ma to 1.8 Ma - based on 8 recorded ages.
