It has an embedded beauty to my eye. NWA 12520 is a single stone primarily composed of olivine and orthopyroxene. 410g.
MetBull: “Relatively fresh, shock-modified breccia consisting of clasts of petrographic type 6 and shock stage S1 (largely recrystallized with rare chondrule remnants and stained metal) in a very fine grained to glassy matrix (black to cinnamon-brown in thin section).”
Sotheby’s was more poetic: “Fragments of impact melt breccias are cemented together by crystallized impact melt from a massive impact event which generated so much heat that it liquified the target rock which then engulfed the clasts now seen. Grains of metal from one such impactor provide further accenting.
Impact melts most often do not contain clasts and are typically homogenous, hardened slurries. When they contain brecciated fragments, they are often visually compelling and NWA 12520 is no exception. The meteorite from which this complete slice is derived is a snapshot of a cataclysmic impact in interplanetary space frozen in time.”
