Fig. 2

Chondrite-normalized REE pattern of zirconolite from NWA 4485. It is compared with Apollo lunar zirconolites (Norman and Nemchin 2014; Rasmussen et al. 2008; Seddio et al. 2013) and terrestrial grains from tholeiites (Rasmussen et al. 2008) and carbonatites (Wu et al. 2010). The Eu composition in our grain is predicted to be lower than 100 × CI based on Apollo lunar zirconolite studies
