Most meteorites date from the early Solar System and are by far the oldest extant material on Earth. Analysis of terrestrial weathering due to water, salt, oxygen, etc. is used to quantify the degree of alteration that a meteorite has experienced. Several qualitative weathering indices have been applied to Antarctic and desertic samples.
Gas-rich meteorites are meteorites with high levels of primordial gases, such as helium, neon, argon, krypton, xenon and sometimes other elements. [1] Though these gases are present "in virtually all meteorites," [ 2 ] the Fayetteville meteorite has ~2,000,000 x10 −8 cc STP / g helium, [ 3 ] or ~2% helium by volume equivalent.

The Cape York meteorite, also known as the Innaanganeq meteorite, is one of the largest known iron meteorites, classified as a medium octahedrite in chemical group IIIAB. [5] In addition to many small fragments, at least eight large fragments with a total mass of 58 tonnes have been recovered, the largest weighing 31 tonnes (31 long tons; 34 ...
When a meteorite with the mass of four Mount Everests hit Earth 3.2 billion years ago, it caused global chaos and provided an unexpected silver lining for life.
Meteoric iron, sometimes meteoritic iron, [1] is a native metal and early-universe protoplanetary-disk remnant found in meteorites and made from the elements iron and nickel, mainly in the form of the mineral phases kamacite and taenite. Meteoric iron makes up the bulk of iron meteorites but is also found in other
