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
Final Fantasy XIV: In the MMORPG Final Fantasy XIV, Aether is one of the main elements of life and magic in the world. [12] [13] Magic: The Gathering: Aether (previously spelled Æther) is the main type of energy filling the blind eternities in the Magic: The Gathering multiverse, though it can also appear in variable quantities within the planes.

Iron meteorites, also called siderites or ferrous meteorites, are a type of meteorite that consist overwhelmingly of an iron–nickel alloy known as meteoric iron that usually consists of two mineral phases: kamacite and taenite. Most iron meteorites originate from cores of planetesimals, [3] with the exception of the IIE iron meteorite group. [4]
Meteorites composed of 6 wt% or less nickel are often referred to as hexahedrites due to the crystal structure of kamacite being isometric and causing the meteorite to be cubic. Likewise if the meteorite is dominated by the face centered taenite it is called an octahedrite as kamacite will exsolve from the octahedral crystal boundaries of ...
The Chinga meteorite is an iron meteorite. It is structurally an ataxite with very rare kamacite lamella. The meteoric iron is a part of the lamella taenite. [2] The total chemical composition is 82.8% iron, 16.6% nickel, and the rest mostly cobalt and phosphorus. [3]
As all meteorite iron is nickel rich this indicated a meteoritic origin. However, in the 1980s strong doubts developed after suggestions from archaeo-metallurgists that some early examples of nickel rich iron were produced by the use of terrestrial nickel rich iron ores. [13] To establish meteorite provenance more refined analysis was needed.
In February 2009 and 2010, meteorite fragments with masses ranging from < 1 gram (0.035 oz) to 35 kilograms (77 lb), plus an 83 kilograms (183 lb) specimen, were found in and around a 45 metres (148 ft) radius from Kamil Crater by an Italian-Egyptian geophysical team. [2] About 800 kilograms (1,800 lb) was recovered. [2]
