Sierra Gorda 009: A new member of the metal‐rich G chondrites grouplet

open access: yesMeteoritics & Planetary Science, 2020
AbstractWe investigated the metal‐rich chondrite Sierra Gorda (SG) 009, a member of the new G chondrite grouplet (also including NWA 5492, GRO 95551). G chondrites contain 23% metal, very reduced silicates, and rare oxidized mineral phases (Mg‐chromite, FeO‐rich pyroxene).

A statistical investigation into relationships between the IIE irons and the ordinary, F and “HH” chondrites

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 10, Page 2376-2400, October 2025.
Abstract It has been proposed that IIE iron meteorites formed through impact processes on a parent body that was composed of either the H chondrites or a much‐debated fourth ordinary chondrite group, the HH chondrites. To resolve this debate, we have compiled a large dataset for the ordinary chondrites, low‐fayalite ungrouped chondrites, and IIE irons,
