Add to ORKGWe have performed infrared spectroscopy of meteoritic calcium-aluminum-rich inclusions (CAIs) from the CV chondrites Leoville and Allende. While some previous studies have focused on the wavelength range lambda<25 mum, we aimed at a detection and identification of CAI bands at wavelengths from 6 to 75 mum. The resulting spectra have been compared with laboratory mineral spectra of typical CAI constituents such as melilite (a solid solution of gehlenite [Ca2Al2SiO7] and åkermanite [Ca2MgSi2O7]), spinel (MgAl2O4), diopside (CaMgSi2O6), and its Al- and Ti-rich variety fassaite. Sixteen bands in a type-B1 Leoville CAI transmittance spectrum could be assigned to melilite and spinel, 13 bands in the spectrum of a B3 Allende CAI were assigned to A...
