Allende is one of the most primitive meteorites, and it illustrates the history of our solar system better than any other space rock. The calcium-aluminum inclusions (CAIs) seen in CV chondrites were the very first bits of matter to condense out of the solar nebula and even pre-date chondrules by 2-3 million years. The chondrules in Allende formed over 100 million years before the accretion of differentiated bodies like Earth began.
Dozens of CAIs, including some 2-3mm in diameter, are visible in this cross-section. There are also countless chondrules, including many 2-3mm in diameter, plus others that preserve their crystal structures in fine detail. Fusion crust covers ~50% of the exterior edge. This complete slice is an ideal specimen for studying this extremely important meteorite with a hand lens or low power microscope.
