On February 8, 1969, the largest carbonaceous chondrite to be discovered on Earth fell in Pueblito de Allende, Chihuahua, Mexico. Fragments were scattered across Allende, making the meteorite strewn field one of the largest ones documented to date, with a total known weight of 2 metric tons.
The Allende meteorite is classified as a CV3 and has a total composition of about 24% iron. Throughout each specimen, calcium-aluminum inclusions (white crystal-like additions) are evident. On the basis of scientific analysis, these inclusions are estimated to be more than 4.5 billion years old. Allende specimens are older than Earth itself!
