Bus–DeMeo principal component values for all eight aubrite meteorites and their associated grain size bins using the Bus–DeMeo taxonomy classification web tool (F. E. DeMeo et al. 2009). Grain size variations among the same meteorite can be seen by using the dashed–dotted lines connecting them, where marker size increases with grain size. All grain size bins from <45 μm to slab are included for thoroughness, though slab points are unconnected due to their unconstrained grain size. Grain size variation is generally parallel to the α-line, with Rantila as the notable exception that crosses this boundary.
