Abstract
Angrite meteorites represent alkali depleted planetary crust of basaltic composition, and have both plutonic and volcanic lithologies. NWA 15507 is a microgabbroic specimen (mean grainsize ~1.4 mm) composed predominantly of zoned Al-Ti-augite, Ca-bearing olivine and anorthite together with accessory kirschsteinite, rhönite, hercynite, low-Ni kamacite, merrillite, magnetite and troilite. Upon initial investigation, the anorthite was found to exhibit a cathodoluminescence (CL) response which revealed a complex history of crystallization. Hyperspectral cathodoluminescence, quantitative electron probe microanalysis mapping, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), and electron back scattered diffraction (EBSD) were used to determine the CL emitter to better unravel the crystallization history of NWA 15507.
