This exhibit celebrates the acquistion by UCLA and a consortium of five other institutions the new and rare 123lb. Anoka iron meteorite specimens. It illustrates the broad depth of the UCLA Collection which totals 620 meteorites, the fifth largest in the United States, and the largest on the west coast. This exhibit is organized by John Wasson, UCLA Professor of Geochemistry, who is regarded as one of the world's leading experts on meteorites.
Alende: Mexico CV3 carbonaceous chondrite. The small dark spherules are chondrules; the large white chips are refractory inclusions.
Millbillillie: W. Australia Eurcrite. This basalt contains crystals of variable size; they are relatively coarse in this specimen, indicating that it was buried deep enough to cool slowly. The fusion crust on eucrites has a glassy sheen.
Canyon Diablo: Arizona, USA IAB iron meteorite. The impact of this meteorite produced Meteor Craor, a bowl-shaped depression about 1-km in diameter, about 50,000 years ago. The coarse banding indicates that it cooled at a rate of about 10 degrees Celsius per million years
