It is a IAB-MG (Main Group), coarse ochtahedrite and is named "Ocate" after the nearest town to where it was found. It will be in the online database soon and will be published in MB96 (Sept, issue MaPS). It wasn't until 2008 that they finder approached me with the single 6.4kg stone that the classification process began. I went to the find site last fall with the person who found it to take GPS coordinates, photograph the area and to hunt for more if there were any to be found. We didn't have much time to hunt at that time so we did not find any others. Here are a couple of links to give you an idea of how nice Ocate is (see all available specimens below classification below). This was cut and prepared by one of the best meteorite craftsman in the business!

It took us about three hours after leaving the paved road to get to the site up the mountain on a road that was more like a crater-ridden trail with large boulders in most places and swampy mud in others. To successfully hunt the site would require camping for a week, there is no way to drive up and down the mountain each day and get enough hunting hours in to make it worthwhile. There are also lots of elk hunters during hunting season so anyone who wants to give it a go, be careful! Submitted and approved classification for "Ocate": Ocate 36° 17.72' N, 105° 2.90' W Mora County, New Mexico Find: 1986 Iron (IAB-MG), coarse octahedrite History: This single 6.4kg mass was found by a local New Mexico hunter in 1986. Knowing it was different from the surrounding rocks and had an odd appearance (the face of a bear), the hunter took it home and set it aside with an odd assortment of 'collectibles' while hunting and mountaineering over decades in the New Mexico area. The owner contacted G. Hupe in May 2008 for verification of the find, which was confirmed by study of the type sample at the University of Alberta. Physical characteristics: A single stone weighing 6402 grams with virtually no apparent fusion crust, yet also lacking progressed terrestrial alteration, which contributes towards its dark brown metallic appearance with well defined regmaglypts. Petrography: (C. Herd, N. Bruemmer, UAb) A 5 x 7 cm polished and etched slab reveals Widmanstätten pattern with an average bandwidth of 1.4 ± 0.2 mm, few areas of plessite, and numerous inclusions. A 1 cm ellipsoidal graphite nodule and several smaller inclusions of graphite, troilite and schreibersite are associated with polygonal kamacite on one portion of the slab. Smaller, mm-scale elongate inclusions of troilite are oriented parallel to kamacite lamellae where the Widmanstätten is better developed. Terrestrial oxides decorate fractures within a few mm of the exterior surface. Geochemistry: Bulk Composition: INAA data (J. Duke, UAb): Ni = 6.99 ± 0.05 wt%, Co = 0.466 ± 0.004 wt%, Ga = 71.9 ± 0.3 μg/g, Ge = 271 ± 6 μg/g, Ir = 2.25 ± 0.04 μg/g, Au = 1.60 ± 0.03 μg/g, As = 15.2 ± 0.3 μg/g, Cu = 119 ± 11 μg/g, W = 0.87 ± 0.08 μg/g, Re = 0.22 ± 0.02 μg/g (uncertainties 1s, 68% confidence level). Classification: Iron meteorite, IAB main group, coarse octahedrite, minimal shock, minimal weathering. Type specimens: 97.58 g slab and a 3.2 g interior piece, UAb, main mass, G. Hupe. I have only 12 specimens out of 15 that are available, here is the list which also shows the thickness of each piece: Ocate, New Mexico IAB-MG iron meteorite 910g end cut http://www.lunarrock.com/ocate/specimens/nm910a.jpg http://www.lunarrock.com/ocate/specimens/nm910b.jpg 322.6g cs 4mm thick http://www.lunarrock.com/ocate/specimens/dsc00001.jpg 314g cs 4mm http://www.lunarrock.com/ocate/specimens/dsc00002.jpg 211.6g cs 3.5mm http://www.lunarrock.com/ocate/specimens/dsc00003.jpg 208.2g cs 4mm http://www.lunarrock.com/ocate/specimens/dsc00004.jpg 191g cs 4mm http://www.lunarrock.com/ocate/specimens/dsc00005.jpg 168.6g cs 2.5mm http://www.lunarrock.com/ocate/specimens/dsc00006.jpg 163.8g cs 2.5mm http://www.lunarrock.com/ocate/specimens/dsc00007.jpg 162.9g ps 6.5mm http://www.lunarrock.com/ocate/specimens/dsc00008.jpg 162.8g cs 3.5mm http://www.lunarrock.com/ocate/specimens/dsc00009.jpg 130g ps 5-7mm http://www.lunarrock.com/ocate/specimens/dsc00010.jpg 4.5g ps (unpolished) 5mm http://www.lunarrock.com/ocate/specimens/dsc00011.jpg cs - complete slice ps - part slice I am asking just $4.00/g plus shipping, so if you are interested, please contact me Off-List.
