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 ...
Some carbonaceous chondrites, such as the Allende meteorite, contain calcium-aluminum-rich inclusions (CAIs). These are compounds that emerged early from the primeval solar nebula , condensed out and represent the oldest minerals formed in the Solar System .

In meteoritics, a meteorite classification system attempts to group similar meteorites and allows scientists to communicate with a standardized terminology when discussing them. Meteorites are classified according to a variety of characteristics, especially mineralogical , petrological , chemical , and isotopic properties.

Anders went on to study samples of the Allende meteorite, the largest carbonaceous chondrite ever found on Earth. Results of these studies suggested elements 111–115 (today roentgenium, copernicium, nihonium, flerovium, and moscovium) [4] as the most likely candidates for the progenitor of CCF Xe.
Notably, his work delves into analytical chemistry, stable isotope ratios, and magnesium isotopes within the framework of Allende meteorite investigations. [ 2 ] His honors include the Robert J. Trumpler Award in 1978 from the Astronomical Society of the Pacific , and Outstanding Researcher Awards from the National Science Council in 1985-87 ...
