Member of:

Brittle Mica Group > Mica Group

Name:

Named in 1967 by D. B. Pattiaratchi, Esko Saari, and Thure Georg Sahama in honor of Ananda Kentish Coomaraswamy [August 22, 1877 Columbo, Sri Lanka (Ceylon)− September 9, 1947 Needham, Massachusetts, USA], briefly, the first director of the Mineral Survey of Ceylon. In 1906, he left geology, moved to New York City, New York, USA, and became a noted philosopher.

Type Locality:

ⓘ Wilagedera iron prospect, Kurunegala District, North Western Province, Sri Lanka

Mica Group.
An unusual sulphur-bearing member of the mica group with three known polytypes: anandite-2M1, anandite-1M, and anandite-2O (the most common polytype at the type locality). All anandite polytypes resemble each other, nearly opaque black mica.
