A meteorite mineral is a mineral found chiefly or exclusively within meteorites or meteorite-derived material. [citation needed] This is a list of those minerals, excluding minerals also commonly found in terrestrial rocks. As of 1997 there were approximately 295 mineral species which have been identified in meteorites. [1]
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
Troilite (/ ˈ t r ɔɪ l aɪ t /) is a rare iron sulfide mineral with the simple formula of FeS. It is the iron-rich endmember of the pyrrhotite group. Pyrrhotite has the formula Fe (1-x) S (x = 0 to 0.2) which is iron deficient. As troilite lacks the iron deficiency which gives pyrrhotite its characteristic magnetism, troilite is non-magnetic ...
0.1, in which both iron and nickel have the valence zero (Fe 0 and Ni 0) as they are metallic native elements commonly found in iron meteorites. Besides trace elements, it is normally considered to be made up of 90% iron and 10% nickel but can have a ratio of 95% iron and 5% nickel. This makes iron the dominant element in any sample of kamacite.
They were first discovered in the 19th century by ore prospectors who mistook the shiny metal inclusions for silver and thought they had found an outcrop of a silver ore deposit. Later when an analysis was made and nickel-iron was found, the true nature as a meteorite was established. The meteorite was called Vaca Muerta. [3]
Many masses were found strewn in a field, with a total weight of about 820 kg. An additional mass of 227 kg was found at a depth of 10 feet (3.0 m) in 2002. Esquel, Chubut, Argentina. A large mass of 755 kg was found embedded in soil before 1951. Pallasovka, Pallasovka, Russia. A single mass of 198 kg was found near Pallasovka, Russia in 1990.
The exact worth of a meteorite varies depending on the specific type of meteorite in question. An 82-pound iron meteorite originating from an asteroid recently sold for $44,100 — about $540 per ...
Most iron meteorites originate from cores of planetesimals, [3] with the exception of the IIE iron meteorite group. [4] The iron found in iron meteorites was one of the earliest sources of usable iron available to humans, due to the malleability and ductility of the meteoric iron, [5] before the development of smelting that signaled the ...
