CONCEPTION JUNCTION METEORITE - LARGEST COMPLETE SLICE & COVER IMAGE OF METEORITE MAGAZINE
Pallasite - PAL
Conception Junction, MO - (40° 16'N, 94° 41'W)
Discovered as a result of the community outreach efforts on the part of meteorite hunter Karl Aston, this complete pallasite slice was cut from a meteorite found protruding from a hillside near Conception Junction, Missouri. The exterior of the meteorite was weathered, while the interior showed only minor oxidation. Classified in 2011 by UCLA's Dr. John Wasson, the world's foremost authority on iron and stony-iron meteorites, Conception Junction is chemically and morphologically unique among pallasites - the olivine is primarily circular and unusually plentiful. Following the quiet acquisition of the 17 kilogram mass from the landowner, a 16-month search of the surrounding area ensued for additional specimens - which turned out to be fruitless.

Accompanying this lot is the November 2011 issue of Meteorite, in which this specimen is featured on the cover, as well as a detailed monograph written on Conception Junction by Dave Gheesling, curator of the Falling Rocks and Back Plate meteorite collections. This is the largest complete slice of an eminent American pallasite. 229 x 197 x 7mm (9 x 7.75 x 0.25 inches) and 872.96 grams (1.9 pounds).
