Accretion textures. (A) Meteor Crater: glassy impactite with multiple accretionary objects deformed by collisional impact (no. 1). (B) Talega site: cluster of large quenched spherules with smaller partially buried spherules (no. 1), accretion spherules (no. 2), and accreted carbonaceous matter (no. 3). (C) Meteor Crater: accretion spherule on larger host with impact pit lined with carbon (no. 1), quenched iron oxide surface crystals (light dots at no. 2), and melt draping (no. 3). (D) Melrose: YDB teardrop with a quench crust of aluminosilicate glass and a subcrust interior of SiO2 and Al-rich glasses, displaying melt drapings (no. 1), microcraters (no. 2), mullite crystals (no. 3), and accretion spherules (no. 4).
