New chondrite find from Sahara. (contact: Albert JAMBON UPMC, Paris)
Discovery: Between February and June 2001, a person prospecting for meteorites in Sahara found 42 individuals of the same fall for a total weight of 10,850 Grams. The larger individual weighs 1065 grams and presents flights marks and fusion crust. In November 2001 and January 2002, a party under supervision of the first discoverer recovered additional 400 kg of the same meteorite. The bigger individual recovered weighs 28 kg. Individuals between 1 and 10 kg present deep and well marked regmaglypts. Most individuals above 10 kg broke up on landing. Some more individuals were found in 2003. for a weight of 46 kilos.
Type Specimen: ENS Lyon/Philippe Gillet (one wafer of 26.25g, one end cut of 62.09g) and UPMC Paris/Albert JAMBON one stone with nearly complete fusion crust (516.16 g), one end cut (19.07g) and one wafer (26.45 g).
Main mass:: Caillou Noir: 410 kg. ( submitted to Nom Com ) Additionnal mass 46 kilos.
Coordinates: latitudes: from llb° 28'029 to llb° 02'198 Longitudes: from LLb °03'252 to (LLb-1)° 50'543
Note: llb and LLb are positive integers that will be disclosed later by finder. Coordinates of type specimen: llb°16'007 et (LLb-1)°56'946
Classification: Chondrite : L3.8, S2, W1
Macroscopic Aspect : Nearly complete brown greenish fusion crust. About 60% chondrules, from one mm to nearly 50 microns, grey and white in a slightly oxydized matrix. Numerous clasts (about 5-10% vol, but this is only a guess due to statistical considerations) of several types. 1) some dark to light grey and angular from a few mm to several cm. 2) brown and irregular 3) Angular dark-brown from a few mm to a few tenths of mm. Metal and sulfide occur as spot of a few mm to a few tenths of mm. Conspicuous signs of oxydation.
Mineralogy: olivines Fo 74 ±2 (68-86), pyroxenes Mg#77±5 (68-86). Numerous clasts of small size (a few mm or less) some of which dark and nearly opaque others sub-opaques or well cristallized without matrix with broken chondrules some of small size and made up of matrix. Typical porphyric chondrules, a few barred chondrules, sometimes broken. Some devitrified partially vitrous. Metal and sulfides partly oxydized.
Main mass at Caillou Noir, 100 chemin des Campènes, 74400 Chamonix, France.
