Eucrite is also a now obsolete term for bytownite-gabbro, an igneous rock formed in the Earth's Scotland.
A rose-colored mineral named roselite is named after Rose, and he is credited with coining the terms howardite and eucrite.
3103 Eger is the only asteroid besides 4 Vesta identified as the parent body for specific meteorites . 4 Vesta is the parent body for Howardite, Eucrite, and Diogenite meteorites, while 3103 Eger is the parent body for Aubrite meteorites.
Dating of howardite, eucrite and diogenite ( HED ) meteorites and H chondrite meteorites originating from the asteroid belt reveal numerous ages from 3.4 4.1 Ga and an earlier peak at 4.5 Ga . The 3.4 4.1 Ga ages has been interpreted as representing an increase in impact velocities as computer simulations using hydrocode reveal that the volume of impact melt increases 100 1000 times as the impact velocity increases from the current asteroid belt average of 5 km / s to 10 km / s.
