The Chergach meteorite is an H5 type meteorite that fell in Mali on July 2, 2007.
In autumn and winter 2007, about 100 kg of meteorites were collected in Erg Chech, north of Taoudenni. The nomads reported that the stones fell after a cloud of smoke was seen and several detonations were heard over a wide area during the day in July 2007. The discoverer of the first meteorites was Mr. Ouled Bleila, who died in a car accident on his way home from visiting the Chergach field in October 2007. According to Tuaregs from Algeria who visited the falls site in September 2007, the elliptical falls field stretches over 20 km in a northeasterly direction. No fireballs were reported.

Jdiriya 004 is a rare and fresh rumuruti R3 chondrite weighing only 142 grams.
Magnetic susceptibility, chondrule diameters, mineral chemistry and texture suggest that it is an R3-4 breccia.
Only 10 meteorites of this type are classified to date.
The R chondrite group does not clearly belong to any of the major chondrite classes (ordinary, carbonaceous, enstatite); R chondrites have sub-solar Mg/Si and refractory/Si ratios, oxygen isotopic compositions that are above the terrestrial fractionation line and ordinary chondrites, and strongly oxidized mineralogy.
The first R chondrite, Carlisle Lakes, was found in Australia in 1977.
