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 ...
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.
The planet's economy comes to depend on mining and sale of duodecimate ores. It is not revealed what the substance is actually used for. Duranium: Star Trek: The fictional metal duranium is referred to in many episodes of Star Trek as extremely hard alloys used in starship hulls and hand-held tools. Dureum Lensman
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]
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
Various Ultimania books at a Books Kinokuniya in San Francisco, California. Dozens of Square Enix companion books have been produced since 1998, when video game developer Square began to produce books that focused on artwork, developer interviews, and background information on the fictional worlds and characters in its games rather than on gameplay details.
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 ...
Enstatite is a common mineral in meteorites. Crystals have been found in stony and iron meteorites, including one that fell at Breitenbach in the Ore Mountains, Bohemia. In some meteorites, together with olivine it forms the bulk of the material; it can occur in small spherical masses, or chondrules, with an internal radiated structure. [5]
