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 Allende meteorite has shown to be full of new minerals, after nearly forty years it has produced one in ten of the now known minerals in meteorites. [2] This CV3 carbonaceous chondrite was the largest ever recovered on earth and is referred to as the best-studied meteorite in history. [2] The inclusion has only been viewed via electron ...
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 is a molybdenum dominant alloy discovered during a nanomineralogy investigation of the Allende meteorite. [4] Hexamolybdenum was discovered in a small ultrarefractory inclusion within the Allende meteorite. [4] This inclusion has been named ACM-1. [4] Hexamolybdenum is hexagonal, with a calculated density of 11.90 g/cm 3. [4]

Panguite is a type of titanium oxide mineral first discovered as an inclusion within the Allende meteorite, and first described in 2012. [4] [5]The hitherto unknown meteorite mineral was named for the ancient Chinese god Pan Gu, the creator of the world through the separation of yin (earth) from yang (sky).
