Essentially vermiculite is a member of the phyllosilicate group of minerals, resembling mica in appearance.

It is found in various parts of the world, but currently the major mines are located in South Africa, China, Brazil, Zimbabwe, and the United States.

The largest operating mines today are located in the Palabora region of North-Eastern Transvaal in South Africa, in the northwestern corners of China, and along the eastern Appalachian range in the United States (Virginia and South Carolina).

The vermiculite ores from these mines are different forms of hydrated phlogopite or biotite mica which has the remarkable ability of being able to expand to many times its original volume when heated---a property known as exfoliation.
