Allende slab
Allende is a carbonaceous chondrite which fell in
Chihuahua, Mexico. Most of the light-gray objects visible in this sawn
slab are millimeter-sized chondrules, while the larger white objects are
refractory inclusions; both are embedded in black matrix material. This
primitive chondrite fell just a few months before the Apollo 11 astronauts
landed on the Moon, providing a unique opportunity for scientists to test
many of the analytical techniques that they had developed to study the
lunar samples. |
