    For a meteorite to be analyzed, one of the first things to occur is the preparation of thin sections. In a process that is part craft and part art, material is mounted and ground down until it is so thin that light can pass through the various structures seen. When backlit with white light, the texture, mineralogy, and crystalline morphology of the sample become richly evident. As different minerals refract light differentially, when viewed through polarized light, each mineral displays a vivid color. This lot contains a thin section of NWA 5717 prepared by Steve Schoner - which contains some of the most primitive planetary material known (see lot 49008); a thin section of NWA 5240 - a carbonaceous meteorite that contains CAIs (see lot 49004); and finally, an historic thin section of Claxton, one of the most famous American meteorites, known for landing directly in - and through - a mailbox in Claxton, Georgia. The thin section of Claxton is accompanied by packaging from Andrew Graham of the British Museum of Natural History. Thin sections: average of 40 x 20 x 2mm. Claxton: 49 x 27 x 1mm (2 x 1 x 0.05 inches)
