Table 2 lists the Antarctic meteorite populations of each of the meteorite subtypes. The last subtype in each major type is that for rare or unusual meteorites. These generally include several different types of meteorites, as for example, the achondrites include acapulcoites, angrites, brachinites, lunar and martian meteorites. This surprising abundance of rare meteorites in Antarctica is attributed to the fact that it is easier to find small meteorites on ice than on land. An exception to this is the planetary meteorites.
Martian meteorites are generally large.
1900g and 7900g. It would appear that a difference in impact dynamics makes these rare planetary meteorites larger specimens. Populations of US Antarctic meteorite subtypes. Percentages are based on pairing-corrected numbers of meteorites, except for ordinary chondrites which are uncorrected. 0.1 Figure 3.
