Chunky Allende Meteorite with Crust! 8.5g - From A Carbonaceous Asteroid!

The Allende meteorite, which fell in February 1969 in Chihuahua, Mexico, is one of the most significant meteorites ever recovered. It is classified as a carbonaceous chondrite, specifically belonging to the CV3 group. This type of meteorite is known for containing a wealth of organic compounds and presolar grains, providing valuable insights into the early solar system.

The Allende meteorite is notable for its large size—over 2 tons were recovered, making it the largest carbonaceous meteorite found to date. Its irregularly shaped fragments displayed a distinctive appearance, with mottled patterns of light and dark material, reflecting its complex mineralogy.

Scientific studies of the Allende meteorite have revealed clues about the conditions that existed in the early solar nebula. It contains a variety of minerals, including olivine, pyroxene, and refractory inclusions, which are thought to have formed in the high-temperature regions of the solar system. Additionally, the presence of amino acids and other organic compounds in the meteorite raises intriguing questions about the origins of life and the building blocks of organic matter.

The Allende meteorite has not only contributed to our understanding of planetary formation but has also sparked discussions about the potential for life beyond Earth. Its rich scientific significance makes it a key specimen in the study of meteoritics and astrobiology.

About Carbonaceous Chondrites:

Carbonaceous chondrites are a significant subset of stony meteorites that provide valuable insights into the early solar system's history. These meteorites make up an extremely small portion of the total number of fallen meteorites and are classified into several distinct, rare groups, based on their chemical composition, mineralogy, and oxygen isotopic signatures. 

Like other chondrites, carbonaceous chondrites have undergone varying degrees of alteration, whether through exposure to water, heat, or a combination of both. One group, CI, has undergone such extensive alteration that few of its original features remain. Interestingly, these meteorites no longer exhibit any signs of chondrules, which are a defining characteristic of chondrites. Despite this, scientists continue to classify them as part of the chondrite family due to their chemical makeup and other distinctive features.

Fun Fact:  Not all carbonaceous chondrites contain significant amounts of carbon, even though it was thought to believe that the dark matrix meant otherwise. The dark color is actually a result of the abundance of fine-grained matrix in these meteorites.

About Stony Meteorites:

Stony meteorites are the most common meteorites, making up the majority of the meteorites discovered here on Earth.  They are divided into two groups: chondrites, which are some of the oldest primitive material in our entire solar system originating from large asteroids, and achondrites, which include meteorites that derived from our moon and Mars.

*Note - Lunar and Martian-originated meteorites will always be indicated as such on the listing. Any other meteorite listed will have originated from an asteroid.
