Meteoritics &Planetary Science, EarlyView.Abstract This study investigates the petrography and mineralogy of three L‐type ordinary chondrite meteorites: Northwest Africa (NWA) 4137 (L6), Homestead (L5), and Kunashak (L6). We studied the shock‐related deformation features in the matrix and the characteristics of the melt veins, including the presence or absence of high‐pressure (HP) phases. Our

A Microkrystite from the Australasian Tektite/Microtektite Strewn Field
Meteoritics &Planetary Science, EarlyView.Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the
