PAL - Pallasite
Atacama Desert, Chile
Similar to the previous lot. Nothing known on Earth resembles this remarkably beautiful material. Fine pallasitic meteorites are the most sought-after meteorites, and this complete slice amply reveals why specimens of Imilac are among the most coveted. All pallasitic meteorites - less than 1% of all meteorites - originate from the boundary between the stony mantle and molten iron core of a planetary body that broke apart during the formation of our solar system (whose remnants are part of the asteroid belt). The olivine crystals seen here are the result of small chunks of stony mantle becoming suspended in molten nickel-iron which slowly cooled and crystallized over a million years in the vacuum of outer space. Imilac occasionally contains - as does this example - gem-quality olivine or peridot, the birthstone of August. This specimen has the archetypal dispersion of Imilac olivine crystals, and a complete rim of fusion crust. Found in the Atacama Desert in Chile, the source material is now thoroughly exhausted. It is now difficult to obtain large complete slices of what is inarguably the most resplendent extraterrestrial material known, of which this is a select example. 160 x 148 x 3 mm (6.33 x 5.75 x 0.1 inches) and 246.9 grams (0.5 pounds).
Provenance: The Macovich Collection of Meteorites.
