$129.00

Description

On October 16, 2003, a fireball exploded in the sky over a remote area of the Western Sahara Desert near a militarized border. Moroccan soldiers made the first recoveries, which entered under the market under the names of Amgala and Gor Lefcah. Those early stones were pristine and free of oxidation. Later recoveries were not as pretty, complete, or fresh. The meteorite was analyzed and classified as an H3-5 chondrite that is shocked and brecciated.

This specimen is one of the earlier stones that has very fresh crust that is 99% complete across an aerodynamically-sculpted stone. On close examination with a loupe, fine flowlines and rollover lipping is seen. You don't see fine examples of this fall like this any more. This is by far, the nicest and freshest Oum Dreyga I have seen in the many years since the fall - the crust even has that bluish tint to it that some well-preserved fresh falls have.

Refer to the photos. The black centimeter cube is shown for scale and is not included. You are purchasing the specimen shown. It is a whole uncut stone that weighs approx. 21 grams. The fusion crust is 99% complete with just a tiny chip on one corner. The stone displays well in several positions.

Ordinary chondrite (H3-5)

On 16 October 2003, Moroccan soldiers stationed in Western Sahara saw  a meteorite falling on Gour Lafkah Mountains, south of Zbayra, about 21 km from Oum Dreyga. The meteorite fell near a 670 km long wall built in 1985, protected by antipersonnel mines, and guarded by soldiers. About 17 kg were recovered. Stones from this fall were later brought to Moroccan dealers. Most of them have been collected after a rainfall and are thus slightly oxidized. However, some fragments have been picked up soon after the fall; these are very fresh. Fragments have been sold under the names Amgala and Gor Lefcah. Classification and mineralogy (M. Bourot-Denise, MNHNP): very fresh, with a black fusion crust; H3-5 breccia  (Fa16.7± 6.0; 19.5 ± 0.8; Fs14.4 ± 4.4; 17.4 ± 1.3), S4, W0. Specimens: type specimen 20 g and two polished mounts, MNHNP; one 1 kg complete stone and 30 fragments totalling 862 g with PThomas.
