PLATE PREFACE
The following plates highlight 80 samples from the
collection that have influenced either the general field
of meteoritics or the definition and understanding of
specific meteorite groups. They are listed starting with
chondrites (ordinary, carbonaceous, enstatite, Rumuruti,
and K chondrites along with associated ungrouped
chondrites), followed by achondrites including major
achondrite groups, and lunar and martian meteorites.
For each sample the following information is presented:
Sample names are abbreviated as explained in chapter 2
of this topic, and sample localities are presented in map
Figures 2.1a to 2.1e from that chapter.
Classifications, masses (in grams), dimensions, find
dates (by ANSMET teams), and weathering grades are
taken from the NASA-JSC classification database (
www.
curator.nasa.gov
) and associated field and curation data.
For each sample we present a combination of field
photos, lab images, and thin section images. For some
samples field photos are not available, and lab and/or thin
section photos may not illustrate features clearly.
Therefore, all three are not always presented for each
sample. Cubes present in meteorite images are 1 cm on
each side.
For each sample, we present a general overview of each
meteorite type, a summary of the mineralogy, and the
significance of that sample within the field of meteoritics
or within that particular meteorite group.
Additional images for the plates were chosen to high-
light some significance aspect of the sample, and are
taken from peer reviewed literature published for the sam-
ples. References for each sample are presented at the end
of the plate section. These references are meant to reflect
a broad range of research carried out on the Antarctic
meteorite collection but are not necessarily comprehen-
sive. Specific references are called out by number in the
mineralogy and significance sections.
