The Allende meteorite is a CV3 carbonaceous chondrite that fell over the Mexican state of Chihuahua in February 1969. It contains calcium-aluminum-rich inclusions, refractory components that formed during the earliest stages of the Solar System and rank among its oldest dated solid materials. The large amount of recovered material has made Allende an important scientific reference for studying pla...

Ornans is a carbonaceous chondrite meteorite that fell near Ornans in the Doubs department of France in 1868. It is the type specimen for the CO, or Ornans-type, group of carbonaceous chondrites, whose members contain abundant small chondrules and primitive rocky material.
