    COMPLETE SLICE OF HENBURY - GLIMPSE INTO AN IRON METEORITE'S INTERNAL STRUCTURE
    Iron - IIIAB
    Northern Territory, Australia - (24° 34'S, 133° 10'E)
    Similar to the previous lot, this complete slice reveals the internal crystalline structure of a Henbury meteorite - a latticework found only in select iron meteorites. When the planetary body from which this meteorite originated broke apart billions of years ago, the hot, massive metallic core found few molecules in the vacuum of space to which it could transfer its heat, thus providing sufficient time - millions of years - for the molecules of the alloys, kamacite and taenite, to form their octahedral crystalline habit. As there is no other environment other than the vacuum of space that can provide such an extended cooling curve, the presence of this pattern, known as a Widmanstätten pattern, is diagnostic in the identification of a meteorite. The medium octahedral banding of Henbury meteorites can be contrasted with that of other crystalline patterns (see lots 49045 and 49058). 251 x 138 x 3mm (10 x 5.33 x 0.1 inches) and 584.5 grams (1.33 pounds).
