The shergottites are a subset of the Shergottites Nakhlites Chassignites (SNC) meteorites, which are believed to have come from Mars. Petrologic studies of these basaltic meteorites suggest that the most primitive shergottite composition is the groundmass of EETA79001 (a lithology). This inference is based on (1) its high Mg relative to the other shergottites; (2) it normative olivine; and (3) its lack of the cumulate crystals found in most other SNC meteorites. However, the relationship between this primitive composition and the compositions of the other, more evolved shergottites cannot be discovered through petrologic investigations alone. Therefore, liquidus phase relations were experimentally determined for a synthetic EETA79001A groundmass composition at 1 bar and QFM in order to find whether the bulk compositions of other shergottites could be derived by simple equilibrium or fractional crystallization of the EETA79001A groundmass composition.
