Here, we compare the texture, mineralogy, mineral chemistry, and geochemistry of REE-enriched intrusive shergottite groups, including poikilitic shergottites, olivine\u2013gabbroic shergottites, and gabbroic shergottites. Due to the similarities of olivine\u2013gabbroic samples to poikilitic and gabbroic shergottites, we suggest that the former may represent an intermediary petrologic type. We suggest a shared magmatic history for these sample groups via a shared stratified magma chamber. Thermodynamic modeling of the proposed shared magmatic history using Magma Chamber Simulator (MCS) and MELTS was able to reproduce the mineralogies and general crystallization histories of samples using a parental melt of bulk silicate mars (BSM) composition and the compositions of olivine\u2013phyric shergottites LAR 06319 and NWA 6234.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>S.
