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.
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 ...
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]
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]
A Meteorite mineral is a mineral found chiefly or exclusively within meteorites, as opposed to minerals also found commonly on Earth, such as Olivine. The main article for this category is List of meteorite minerals .
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
Extraterrestrial element found in meteorites. The German research team Group 935 discovers it in northern France in 1918 where zombified Christian knights infect the research team. Seen throughout the 'Zombies' storyline, it powers energy weapons, zombifies (and in some cases mutates) humans, increases the abilities of humans, can bend time and ...
The meteorite was called Vaca Muerta. [3] The picture at right shows a cut and polished piece of Vaca Muerta. The most recent fall of a mesosiderite occurred at Dong Ujimqin Qi in China, on September 7, 1995, where three large pieces with a total mass of 129 kilograms (284 lb) fell.
