Summary of Mining and Environmental Planning Aspects of
The Fire Clay coal bed in the Central Appalachian basin region contains a laterally-persistent tonstein that is found in the coal throughout most of its areal extent. Tonstein is a hard compact sedimentary rock that is composed mainly of kaolinite or less commonly other clay minerals suchas montmorillonite and illite.
