Haggertyite

From Wikipedia, the free encyclopedia

Haggertyite is a rare barium, iron, magnesium, titanate mineral: Ba(Fe²⁺₆Ti₅Mg)O₁₉ first described in 1996 from the Crater of Diamonds State Park near Murfreesboro in Pike County, Arkansas. The microscopic metallic mineral crystallizes in the hexagonal system and forms tiny hexagonal plates associated with richterite and serpentinitized olivine of mafic xenoliths in the lamproite host rock. It is an iron(II) rich member of the magnetoplumbite group. It is a light grey mineral with Mohs hardness of 5.

It was named for Stephen E. Haggerty (b. 1938), formerly of the University of Massachusetts, and of Florida International University in 2007.
