Lot 777
Meteorite Etched Gibeon Slice. Gibeon iron-nickel meteorites are in very high demand as they are hard to find and possess the most beautiful internal crystalline structure when cut and etched. Gibeon meteorites were found in the Kalahari desert of Namibia, Africa from a fall that occurred thousands of years ago. This large 5.25 x 4 x .4 inch, 1002 gram (over 2.2 pounds) section has an extremely detailed, beautiful octahedral Widmanstatten pattern. This interesting geometric pattern resulted from the separation of two alloys of nickel, taenite and kamicite that occurred on the large parent asteroid before it was blown apart early in the formation of the solar system. This crystalline pattern does not exist on any rocks on earth and only forms when the iron core of the asteroid cools very slowly at no more than one degree Celsius per million years. This slice is from an old collection and has the original fusion crust on top. It is protected in a 8 x 6 inch Riker mount. Estimated Value $900 - UP
