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.
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 ...
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]
Since the characteristics of lonsdaleite are unknown to most people outside of scientists trained in geology and mineralogy, the names "lonsdaleite" and "hexagonal diamond" have frequently been used in the fraudulent sale of worthless ceramic artifacts, passed off as meteorites on online e-commerce sites and at street fairs and street markets ...
Christopher said he found the meteorite on a dry lake in southern California where he regularly goes meteorite hunting. He then sent a small chunk of it over to UCLA for testing and viola, they ...
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]
The only place it is found is the pits of Hathsin, where small nuggets form in geodes mined by slaves. Using allomancy near the crystals that form the geodes, destroys them. When used by a Feruchemist, it allows them to store age and, if compounded, can cause a complete stop of ageing. Its name comes from the holder of the shard, Ati.
