We have not yet identified any other parent asteroids with as much certainty, but we know from their composition that the Aubrites and the Ureilite
meteorites are rocks from the mantles of two different asteroids that had violently explosive eruptions, which ejected what should have become their crustal rocks into space at escape velocity.
Recently a NASA scientist was asked by an American broker (not Haag) to analyze a rare ureilite
stone of "unknown origin.
3]'s meteorites are largely ureilites
, a weird set of rocks from a body that melted and was then blown to smithereens a few million years after it formed," says geochemist Ed Scott (University of Hawai'i).
It's plotting in a region of oxygen isotope space where we've never had meteorite data points before-except for a few ureilites
, which also have oddball chemistry," he said.
Their analyses revealed that the fallen stones belong to a rare meteorite class known as ureilites
, dark carbon-enriched rocks that were once at least partly molten.
