Crystallization histories of the group IIF iron meteorites and Eagle Station pallasites

Hilton, Connor; Ash, Richard; Walker, Richard (Wiley - Meteoritics & Planetary Science, 2020)

The group IIF iron meteorites and Eagle Station pallasites (PES) have highly siderophile element abundances (HSE; Re, Os, Ir, Ru, Pt, and Pd) of metal that are consistent with formation in planetesimal cores by fractional ...
Supplementary Research Data for "Brachinites record divergent evolutionary pathways"
