Bentonite is absorbent aluminum phyllosilicate generally impure clay consisting mostly of montmorillonite (Na,Ca)0.33(Al,Mg)2Si4O10(OH)2·(H2O)n.
The absorbent clay was given the name bentonite by an American geologist sometime after its discovery in about 1890 – after the Benton Formation (a geological stratum, at one time Fort Benton) in eastern Wyoming’s Rock Creek area.
