Shulamitite
Shulamitite is an IMA-recognized mineral species in the oxides & hydroxide class, with the chemical formula Ca₃TiFe³⁺AlO₈.
It crystallizes in the orthorhombic crystal system (space group Pmma). It is a member of the Perovskite, Brownmillerite structural group.
Key properties: Mohs hardness 6–7; Light brown streak; Adamantine to submetallic luster.
IMA symbol Sla, IMA status: approved, named in 2011.
A major accessory phase in larnite-mayenite metacarbonate rocks formed by combustion metamorphism at very high temperature (1150-1170° C) and low pressure (spurrite- merwinite facies).
It is found associated with Larnite, F-rich mayenite, chromian spinel, ye’elimite, fluorapatite, magnesioferrite.
The mineral was named to honor Dr. Shulamit Gross (1923-2012), emeritus member of the Geological Survey of Israel. The name is also related to biblical Shulamit, red-haired sweetheart of King Solomon.
