The Allende meteorite is the largest carbonaceous chondrite ever found on Earth. The fireball was witnessed at 01:05 on February 8, 1969, falling over the Mexican state of Chihuahua . [ 1 ] After it broke up in the atmosphere , an extensive search for pieces was conducted and over 2 tonnes (2.2 tons) were recovered.
The new mineral was found along with hexamolybdenum. [2] These minerals, are believed to demonstrate conditions during the early stages of the Solar System, as is the case with many CV3 carbonaceous chondrites such as the Allende meteorite. [2] It is named after the Allende meteorite that fell in 1969 near Pueblito de Allende, Chihuahua, Mexico ...
L-excesses from 3 – 15% in several non-protein α-dialkyl amino acids have been found in the Murchison and Murray meteorites. [25] Their extraterrestrial origin is indicated by their absence in biological systems and significant heavy isotope enrichments in 13 C and deuterium compared to terrestrial values. [ 26 ]

Hexamolybdenum lies on a continuum of high-temperature alloys that are found in meteorites and allows a link between osmium, ruthenium, and iron rich meteoritic alloys. [4] The name hexamolybdenum refers to the crystal symmetry (primitive hexagonal) and the molybdenum rich composition. [4] The Allende meteorite fell in 1969 near Pueblito de ...

In fact, the term "stony iron" is a misnomer as currently used. One group of chondrites (CB) has over 50% metal by volume and contains meteorites that were called stony irons until their affinities with chondrites were recognized. Some iron meteorites also contain many silicate inclusions but are rarely described as stony irons.
