Table 6.

Trace element abundances in parent melt of NWA 7325 estimated from plagioclase trace element compositions.

	MgO (%)	K (ppm)	Ti (ppm)	Sr (ppm)	Ba (ppm)
Plagioclase	0.23	26	12	320	0.22
D(plagioclase/melt)^*1	0.037	0.16	0.036	0.92	0.084
Parent melt	6.3	170	320	350	2.6
Abundance/CI^*2		0.30	0.73	45	1.1

^*1

Values for Mg, K, Sr and Ba are from Dohmen and Blundy (2014) assuming Na₂O and CaO wt% of parent melt to be the same as those of bulk 7325 (Barrat et al., 2015). Value for Ti is from Bindemann et al. (1998), assuming T=1500 K and plagioclase composition (X_An=0.9).

^*2

CI chondrite abundance is from Anders and Grevesse (1989).
