摘要: Coesite has been identified within ejected blocks of shocked basalt at Lonar crater, India. This is the first report coesite from crater. occurs SiO2 glass as distinct ~30 μm spherical aggregates “granular coesite” identifiable both with optical petrography and micro-Raman spectroscopy. The coesite+glass only former silica amygdules, which also high-pressure polymorphs forming a secondary mineral. Detailed NMR spectroscopy suggest that crystallized directly localized melt, result complex interactions between shock wave these vesicle fillings.
