Description
Table S1. Compositions of minerals determined by EMP. Fig. S1. Spinel compositions in NWA 6234 and NWA 10170. Fig. S2. Fs-Wo trend for NWA 6234/10170. Fig. S3 Al-Ti trend for NWA 6234/10170. Fig. S4. En Al contents of pyroxene in 6234/10170. Fig. S5. Wo vs Fs content of pyroxene in NWA10414 compared with crystallization PETROLOG calculations of NWA6234 and EET79001A liquid compositions. Orthopyroxene briefly precedes pigeonite in the NWA6234 calculation, which matches crystallization of NWA 6234 better than by EET 0001 (Hewins et al., 2019). Fig. S6. Temperature ranges for the phases crystallized for NWA 6234 using PETROLOG. There is very little difference in temperatures with different pressures. Fig. S7. Crystallization of augite in NWA 6234 by PETROLOG: little variation of Al and Ti with pressure; entry of plagioclase reverses Al trend. Fig. S8. Pyroxene crystallized at 1 bar by First and Hammer (2016) compared to those crystallized by Dann et al. (2001), and to 6234/10170 pyroxene. Fig. S7.
