Antarctic Meteorites
The stony meteorites found in Antarctica are thought to be some of the most ancient, and the least disturbed from the time of their formation. Fraknoi, et al. report that almost all these meteorites have radioactive ages between 4.48 and 4.56 billion years. When the best data and the most accurate values for half-lives are combined, these Antarctic meteorites give an age of 4.54 billion years with an uncertainty of less than 0.1 billion years.

PSRD: Antarctic Meteorites
The total number of Antarctic meteorites is closer to 25,000 when you include Japanese collections (beginning in 1969) and European collections. This large number is uncorrected for pairing--when laboratory examinations show that two or more specimens are actually broken pieces of the same rock. Antarctica (the highest, driest, coldest, windiest, and emptiest place on Earth)...

Pairing Unbound: Fragmentation of Antarctic Meteorites.
Antarctic meteorites are found as accumulations on icefields, and many of these samples are fragments of individual meteorites, or “pairs”. We have used natural and induced TL data to search for potential pairings among 882 Antarctic samples, using literature noble gas concentrations and radionuclide activities as additional criteria when possible. We did not impose geographic proximity criteria, instead using it as an independent test of proposed pairings.

Antarctic Meteorites
Although meteorites have been found in many places, the richest hunting ground for meteorite finds is the Antarctic ice sheet. This is not because more meteorites fall in Antarctica, but because they are easier to find and identify there. There are two primary reasons: 1. Because there are few other sources of rocky material on the Antarctic ice sheet, rocks found there are likely to be meteorites.

Meteorite Mysteries
Antarctica is a special place for collecting meteorites. More meteorite fragments have been recovered there than from the rest of the world combined. Yet because the continent is frozen, remote and uninhabited, not a single Antarctic meteorite fall has been observed. Several factors combine to make Antarctica ideal for finding previously-fallen meteorites.
ABSTRACT
detailed evaluations of Antarctic meteoritic carbonates show that weathering can affect carbonate geochemistry by dissolution-precipitation both before and after ice burial (JULL et al., 1988; JULL et al., 1998; KOPP and HUMAYUN, 2003). In this study, we examine oxygen and carbon isotopes of carbonate minerals from a suite of paired CM2 chondrite meteorites from Elephant Moraine, Antarctica that are described in The Meteoritical Bulletin (GROSSMAN and SCORE, 1996).

Meteorites
A meteorite is a rock from outer space that was once a meteor and has fallen to the earth. Some meteorites are made of broken up pieces of planets. Other meteorites may be parts of comets. ... However, upon close inspection, meteorites differ from earthly rocks in that meteorites contain small specks of metal (primarily iron). In Antarctica, where meteorites are easier to find in the icy, white glaciers, nearly 90% of the meteorites are aerolites or stony meteorites.

Stony-iron meteorites refers to the small group of meteorites that are composed of some metallic alloy, usually in the form of iron and/or nickel. The majority of meteorites - about 86% - are known as stony meteorites because they do not contain any metallic element in their material composition. So it comes to as no surprise that the rarity of pallasites results in their finds to be celebrated and much attention drawn to the total weight recovered.

Leaverites: Meteo-wrongs | It's Not a Meteorite If...
Artificial Materials. Slag and waste metal are especially often mistaken for meteorites. Meteorites do not melt except for a thin surface layer. They do not flatten against the surface they hit, or enclose objects they hit. If it's obviously flattened against a surface or encloses terrestrial objects, it is not a meteorite.

Meteors, Meteorites and Tektites
Meteors, Meteorites and Tektites. A meteor is produced when a bit of rock or dust from outer space enters the earth's atmosphere at a high speed. The friction between this material and the molecules in the atmosphere causes intense heat to build up and makes the material glow -- producing the streak of light people call a "shooting star." A meteor shower is a period when we see an unusually large number of meteors.

An introduction to meteorites
All primitive meteorites are stony, although not all stony meteorites are primitive. Primitive meteoritic material remains largely unaltered by its violent arrival at the Earth's surface. Those meteorites that have experienced major chemical or physical changes since their formation are known as differentiated meteorites.

Comets, Asteroids, Meteorites and Impacts
This is really just all of the little bits that can't be put into the categories of planet or satellite. We'll start off with the very spectacular comets, then the elusive asteroids, followed by the meteoroids-meteors-meteorites and end up with the problems that occur when worlds collide. ... There is even a group of meteorites discovered in Antarctica that are thought to be from Mars.

Studying Meteorites at the University of Central Florida
The current collection of 15 meteorites, which all date from the formation of the solar system 4.6 billion years ago, come primarily from northern Africa and China, and represent a diversity of ancient cosmic materials that are valuable for study. “When you ‘see’ the oldest thing in the solar system, it’s more concrete, more tactile,” Britt says. “There are lots of things we don’t understand yet, but that’s what science is about.”

The meteor’s brightness peaked at an altitude of 29.7 km (18.5 miles) as the object exploded. For nearby observers it briefly appeared brighter than the sun and caused some severe sunburns. The team estimated that about three-quarters of the meteoroid evaporated at that point. Most of the rest converted to dust and only a small fraction (4,000 to 6,000 kilograms, or less than 0.05 percent) fell to the ground as meteorites.

Atmospheric composition 1 million years ago from blue
In the Allan Hills, Antarctica, the antiquity of shallow ice is documented by ter-restrial ages of englacial meteorites exposed on the surface by ablation (6). These ages cluster between 100 and 400 ky, with a small number that extend to 1 Ma and a single meteorite yielding an age of 2.2 Ma (7). Here, we present the first, to our knowledge, direct snapshots of atmospheric composition during the MPT from an ice core.

The antarctic treaty
Activities in the Antarctic had generally been conducted peacefully and cooperatively. Yet the possibility that exploitable economic resources might be found meant the possibility of future rivalry for their control. Moreover, isolated and uninhabited, the continent might at some time become a potential site for emplacing nuclear weapons. Fortunately, scientific interests rather than political, economic, or military concerns dominated the expeditions sent to Antarctica after World War II.

However, Isotope concentrations are significantly different in meteors than that of the Earth’s crust as seen in the K-T boundary layer (Glikson, 2005). ... Iridium-bearing clay is characteristic of the K-T boundary (only boundary rocks) regardless of location. Because meteorites have a much higher concentration of Iridium than that of Earth, we believe that the mass extinction event is largely due to an asteroid approximately 10 km in diameter (Cowen, 1994).

Transcriptomics of iron limitation in Phaeocystis antarctica
P. antarctica is ecologically important due to its contribution in global sulfur gases emissions. Thus, P. antarctica fits as an ideal model organism in understanding phytoplankton adaptation to iron limitation and functional changes following iron addition. Here the results of a transcriptomic study assessing the effect of iron repletion on P. antarctica in a time-series manner are firstly reported. A Ross Sea-endemic P. antarctica clone was acclimated under iron limitation and iron was supplemented to the cultures.

One line of evidence for the overall composition of Earth is found in the composition of meteorites. Many of these are pieces left over from the early solar system, so they are snapshots of the early mix of ingredients that make up our planet. Producing a planet from an accumulation of such fragments will give the correct overall bulk chemistry, but not the proper structure.
