There
are Three Main Types of Meteorites: |
Stoney
Meteorites are the most common
meteorites. They are composed of mostly
silicon-based
minerals. They are heavier than native rock but are
recognizable by their black
fusion
crust outer layer, that looks almost
like a charcoal briquette. They account for approximately
94%
of the
observed meteorite falls.
Iron
Meteorites
are from the core of a planet or asteroid that has been destroyed. As
it's
name
suggests, they consist mainly of iron-nickel metal with small
amounts of sulphide and
carbide
minerals. This is
also the primary component of our Earth's core. These type of
meteorites make up about 5% of the observed meteorite falls. They are
the most recognized meteorite because
of
their weight.
Stoney-Iron
Meteorites
are undoubtedly the most beautiful of all the meteorites. The
Pallasite
Meteorite
falls
into this group. It
is a striking and unusual kind o f meteorite in which olivine
and
iron
are
intergrown in roughly equal proportions; these meteorites are thus
intermediate between stoney and iron meteorites.Their
primary
silicate material is olivine, which is distinguishable by
it's
greenish
hue. Olivine exists here on our earth; as the August birthstone
Peridot.
Only
35 examples of Stoney-Iron Meteorites are
known. |
