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 ...

Carbonaceous chondrites or C chondrites are a class of chondritic meteorites comprising at least 8 known groups and many ungrouped meteorites. They include some of the most primitive known meteorites. The C chondrites represent only a small proportion (4.6%) [1] of meteorite falls.
In 1998, a meteorite, approximately 2.5 millimeters (1 ⁄ 8 in) across, was described from a deep sea sediment core from the North Pacific, from a sediment sequence spanning the Cretaceous–Paleogene boundary (when the site was located in the central Pacific), with the meteorite being found at the base of the K-Pg boundary iridium anomaly ...
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.
