    PALLASITES

    Transitional Meteorite Slice: Seymchan
    Pallasite, PMG
    Magadanskaya oblast', Russia (62° 54'N, 152° 26'E)
    Found: June 1967

    Seymchan is a bit of an "odd duck" among meteorites. For starters, the original mass was found in a creek bed lying among the river rocks - not your normal place to look for such things. A few months after that discovery in 1967, a second piece was found not far away, and in 2004 more material was recovered in the vicinity. The creek bed location is only mildly odd; the seriously interesting thing about Seymchan is that some slices show transitional areas, where the meteorite shifts from having Olivine crystals to areas with no Olivine at all. What this means is that part of the meteorite appears to be IIE Anomalous Coarse Octahedrite type and the rest (the Olivine bearing part) is pallasitic, which leads to a Pallasite, PMG classification. As a result, specimens, like this one show both types in the same slice: a rare occurrence that adds unique character and value to the specimen. A good portion of the beautifully polished slice displays a great Widmanstätten pattern with no Olivine, but very quickly, there is a rapid shift to the high Olivine levels of a classic Pallasite on the edges. The slice has been carefully polished and etched to expose the octahedrite crystal pattern and to show off the great contrast between the Olivine and the nickel-iron. Traces of the original exterior surface are exposed at the edges.
    Overall Measurements: 7.0 x 6.3 x 0.3 inches (17.8 x 16.0 x 0.7 cm), weighs 718 gm (25.32 oz.)
    Offered at no reserve.


    Estimate: $15,000 - $25,000.
