Noncumulate eucrites: have crystallized from basaltic melts on the
s u r f a c e of the HED parent body. Millbillillie is such a non-
cumulate eucrite.
Cumulate eucrites (O.R. Norton, Encyclopedia, Glossary, p. 342): An
igneous rock made up of relatively large crystals that settled out of
a magma by gravity and accumulated on the *floor of a magma chamber*.
