We are a team of meteorite and fossil hunters. We search worldwide for new and known meteorites. Since 1995, we have mounted expeditions to Tsarev, Brahin, Kunya Urgench, Dronino, Markovka, Seymchan, Sikhote-Alin and many others in Russia and nearby. We have also collected many meteorites from North Africa, the Middle East, Europe and the United States. We have gathered samples of almost all types of known meteorites, including a large collection of lunar meteorites. We are on the world market since 2000, and on eBay since 2004. The new Cometshop on eBay is formed from our old cometshop21 that had more then 500 positive feedbacks, more than 2000 good deals with 99.9% positive (before 2006). We ship worldwide from our locations in USA and Germany. (please see careful the location of the item you bid). We easy combine shipping (from one location of course). We accept different ways of payments, but PayPal is very preferred. As always we hope the best is in future. We'll make a very good business with all you our friends and partners. Please do not hesitate ask us any questions. Gebel Kamil Location 22°01'06"N 26°05'16"EEast Uweinat Desert, EgyptFound: 19 Feb 2009Iron, ataxite (ungrouped)History: A total of about 1600 kg of iron meteorite shrapnel (thousands of pieces), ranging in mass from < 1 to 35,000 g, plus a single 83 kg individual completely covered with well developed regmaglypts, was found in and around the 45 m diameter Kamil impact crater by an Italian-Egyptian geophysical team in February 2009 and February 2010. Ca. 800 kg of the total mass observed in the field (the regmaglypted individual inclusive) was recovered. The Kamil crater was identified by V. De Michele, former curator of the Natural History Museum in Milan, Italy. The geophysical survey was carried out within the framework of the "2009 Italian-Egyptian Year of Science and Technology".Physical characteristics: A 634 g type specimen, measuring 88 x 70 x 55 mm, is flattened and jagged shrapnel with a rough, dark-brown external surface. The surface originally sitting in the desert soil shows some oxy-hydroxides due to terrestrial weathering.Petrography: (M. D’Orazio, DST-PI; Luigi Folco, MNA-SI) Etched sections show an ataxitic structure interrupted on a centimetric scale by crystals of schreibersite, troilite and daubreelite enveloped in swathing kamacite. Kamacite spindles (20 ± 5 μm wide) nucleated on tiny schreibersite crystals. The spindles form small aligned clusters and are rimmed by taenite. The matrix is a duplex plessite made of approximately the same proportion of kamacite and taenite lamellae (1-5 μm in thickness) arranged in a micro-Widmanstätten pattern. Many sections show, particularly close to the external surface, shear dislocations offsetting the plessitic matrix and the crystals of the accessory phases by several millimeters.Geochemistry: (M. D’Orazio, DST-PI) Composition of the metal (ICP-MS; D’Orazio and Folco 2003) is Co = 0.75, Ni = 19.8 (both in wt%), Cu = 464, Ga = 49, Ge = 121, As = 15.6, Mo = 9.1, Ru = 2.11, Rh = 0.75, Pd = 4.8, Sn = 2.49, Sb = 0.26, W = 0.66, Re = 0.04, Ir = 0.39, Pt = 3.5, Au = 1.57 (all in ppm). Reference: D’Orazio M. and Folco L. (2003) Chemical analysis of iron meteorites by inductively coupled plasma - mass spectrometry. Geostandards Newsletter: The Journal of Geostandards and Geoanalysis 27, 215-225.Classification: (M. D’Orazio, DST-PI; Luigi Folco, MNA-SI) Iron meteorite (ungrouped), Ni-rich ataxite, extensive shear deformation and low weathering.Specimens: Type specimens: ca. 15 kg and one section at MNA-SI; ca. 5 kg at DST-PI. Main mass of the recovered specimens at Egyptian Geological Museum (Mineral Resources Authority), Cairo, Egypt. Here we offer an excellent complete sample - fragment of this rare meteorite. Weight is 231.5 grams.On the surface you can find some of the impact melt glass.SHIPPING: 1 within USA will be $8.2 outside of USA will be $15 Powered by eBay Turbo... read more
