N2 - Shulamitite, ideally Ca3TiFe3+AlO8, is a mineral intermediate between perovskite CaTiO3 and brownmillerite Ca2(Fe,Al)2O5. It was discovered as a major mineral in a high-temperature larnite-mayenite rock from the Hatrurim Basin, Israel. Shulamitite is associated with larnite, F-rich mayenite, Cr-containing spinel, ye'elimite, fluorapatite, and magnesioferrite, and retrograde phases (portlandite, hematite, hillebrandite, afwillite, foshagite and katoite). The mineral forms reddish brown subhedral grains or prismatic platelets up to 200 mm and intergrowths up to 500 mm. The empirical formula of the holotype shulamitite (mean of 73 analyses) is (Ca2.992Sr 0.007LREE0.007)(Ti0.981Zr 0.014Nb0.001)(Fe3+ 0.947Mg 0.022Cr0.012Fe2+ 0.012Mn 0.001)(Al0.658Fe3+ 0.288Si 0.054)O8. The X-ray diffraction powder-pattern (MoKa-radiation) shows the strongest lines {d [Å](Iobs)} at: 2.677(100), 2.755(40), 1.940(40), 11.12(19), 1.585(17), 1.842(16), 1.559(16), 3.89 (13), 1.527(13). The unit-cell parameters and space group are: a = 5
