The achondrites of this group are named for a Greek philosopher
of the fifth century B.C., Diogenes of Apollonia. He was the first
to suggest that meteorites actually have their origin in outer space,
a fundamental realization that was subsequently forgotten for the
next two thousand years. T
Mineralogically, the diogenites are composed primarily of
magnesium-rich orthopyroxene, with only minor amounts of olivine and
plagioclase. The pyroxenes are usually coarse-grained, suggesting a
cumulate origin for the diogenites in magma chambers within the
deeper regions of Vesta's crust.
