Saliotite is a rare colorless to pearl white phyllosilicate mineral in the smectite group with formula (Li,Na)Al3(AlSi3O10)(OH)5.[2] It is an ordered 1:1 interstratification of cookeite and paragonite. It has perfect cleavage, a pearly luster and leaves a white streak. Its crystal structure is monoclinic, and it is a soft mineral with a hardness rated 2-3 on the Mohs scale.[2][3]
Saliotite was first described in 1994 for an occurrence in an outcrop of high grade schist north of Almeria, Andalusia, Spain. It was named for French geologist Pierre Saliot.[2]
