Sacramento Wash 005 and MET 00428: Impact Generated Sulfide-rich Fe,Ni Melts from the H-Chondrite Parent Body

The H-chondrite parent body has undergone extensive impact cratering resulting in 25% of its members being breccias [1]. One impact has re-sulted in the metallic-melt breccia, Portales Valley (PV); whose Fe,Ni veins resemble the morphology of iron meteorites [2]. Ungrouped iron meteorites either represent single samples from individual parent bodies, or show unique alteration histories from parent bodies of recognized groups [3]. We report the results of our investigation to (1) characterize the S-rich, ungrouped iron meteorites Sacramento Wash 005 (SW), MET 00428 (MET), and HOW 88403 (HOW); (2) compare them to known meteorite groups; and (3) constrain the processes which formed them.
