H Group
This large group counts more than 7.000 members (including lots of
probable pairings), and it has been named for the high content of free
nickel-iron that is characteristic for the meteorites of this group - the
"H" standing for "high iron". H chondrites contain a
weight percentage of 25 to 31% total iron whereas only 15 to 19%
nickel-iron is found in its free, reduced form. Hence, all H chondrites
are attracted to a magnet quite easily.
The H chondrites belong to petrological types 3 - 7, with a
characteristic peak at type 5. More than 3,400 members of this group have
been classified as H5, about 1,800 are H6, and about 1,400 are H4. There
are only about 200 H3s as well as some rare, heavily brecciated members
that contain lithic clasts of several petrological types. The primary
minerals are olivine and the orthopyroxene bronzite. For this reason the H
chondrites have also been called "olivine bronzite chondrites"
or "bronzite chondrites", but those names are no longer in use.
