The most easily recognizable meteorites are the iron variety, although they only

represent about 5 percent of all meteorite falls. They are composed of iron and nickel

along with sulfur, carbon, and traces of other elements. Their composition is thought to

be similar to that of Earth’s iron core, and indeed they might have once made up the

(5)  core of a large planetoid that disintegrated long ago. Due to their dense structure, iron

meteorites have the best chance of surviving an impact, and most are found by farmers

plowing their fields.

 

One of the best hunting grounds for meteorites is on the glaciers of Antarctica,

where the dark stones stand out in stark contrast to the white snow and ice. When

(10)  meteorites fall on the continent, they are embedded in the moving ice sheets. At places

where the glaciers move upward against mountain ranges, meteorites are left exposed

on the surface. Some of the meteorites that have landed in Antarctica are believed to

have come from the Moon and even as far away as Mars, when large impacts blasted

out chunks of material and hurled them toward Earth.

 

(15)  Perhaps the world’s largest source of meteorites is the Nullarbor Plain, an area of

limestone that stretches for 400 miles along the southern coast of Western and South

Australia. The pale, smooth desert plain provides a perfect backdrop for spotting

meteorites, which are usually dark brown of black. Since very little erosion takes place,

the meteorites are well preserved and are found just where they landed. Over 1,000

(20)  fragments from 150 meteorites that fell during the last 20,000 years have been

recovered. One large iron meteorite, called the Mundrabilla meteorite, weighed more

than 11 tons.

 

Stony meteorites, called chondrites, are the most common type and make up more than

90 percent of all falls. But because they are similar to Earth materials and therefore

(25)  erode easily, they are often difficult to find. Among the most ancient bodies in the solar

system are the carbonaceous chondrites that also contain carbon compounds that might

have been the precursors of life on Earth.
