Gebel Kamil
22°01'06"N 26°05'16"E
Country:
Egypt
Al Wadi Al Jadid, East Uweinat Desert, Egypt
Find: 2009
Iron:
Iron
meteorite (ungrouped) Ataxite
Approx.: recovered weight: 1.6 MT
Reported:
Meteoritical Bulletin Database No.
98.
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.

Ich biete Ihnen
hier einen neuen Fund aus 2009, einen Gebel Kamil, Meteoriten, ein
~ very rares ~ Eisen aus der
Ägyptischen
Sahara,
ein
ungrouped Iron - Ataxite,
mit einem niedrigen
Verwitterungsgrad. Seine äußere Beschaffenheit zeigt einen typisch
charakteristischen Verwitterungsgrad der dem Imilac Pallasiten
gleicht, welcher 1822 in der Atacama Wüste, in Chile gefundenen wurde.
Der Gebel Kamil hat die
