Fig. S2. Fs-Wo trend for NWA 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.

图S4 6234/10170中辉石的En-Al含量。
图S5 NWA10414中辉石的Wo与Fs含量关系图，同时对比了NWA6234与EET79001A熔体成分的PETROLOG结晶模拟结果。在NWA6234的模拟计算中，斜方辉石短暂先于易变辉石结晶，该结果相较于EET 0001（Hewins等人，2019）的模拟结果，更符合NWA 6234的结晶演化特征。
图S6 利用PETROLOG模拟得到的NWA 6234结晶相温度区间。不同压力下的结晶温度差异极小。
图S7 利用PETROLOG模拟的NWA 6234中普通辉石的结晶过程：Al、Ti含量随压力变化极小；斜长石的加入使Al含量的变化趋势发生反转。
图S8 First与Hammer（2016）在1巴条件下结晶得到的辉石、Dann等人（2001）结晶得到的辉石，以及6234/10170中的辉石的对比图。
