In a clear sky, a fireball, followed by a trail of smoke was seen over Havana, Cuba, and then fell to the ground in a shower of fragments in the Vinales Valley, 180 km from the capital, in the west of the country… Falling around 1:30 pm local time, on February 1, without causing any casualties, the fall of the meteorite was accompanied by a lightning bolt and a strong explosion. This meteorite was classified as an ordinary chondrite type L6, about 50 kg of this meteorite were found.

This specimen has the particularity to have a primary and secondary fusion crust.
Before arriving on Earth the meteorite broke up, a new thinner crust of fusion was formed.
History: Bought from Zaid Oualguirah in April 2019.
Physical characteristics: Stone with fusion crust. Interior is brown, with visible chondrules.
Petrography: (J. Gattacceca, CEREGE) Equilibrated ordinary chondrite with average plagioclase size below 50 µm. Matrix is scarce and inter-chondrule porosity is high, making chondrules well-delineated.
History: Found in september 2018 by Hammo Oulguirah. Bought in Agadir from finder.
Physical characteristics: Crusted stone with light grey interior.
Petrography: (J. Gattacceca, CEREGE) Highly recrystallized and brecciated chondrite. No relict chondrules was observed in the ~1 cm2 studied polished section. Plagioclase typical size 100 μm. Opaque minerals are Fe,Ni metal (mostly under the form of zoned taenite), FeS, chromite.
Physical characteristics: A single stone with fusion crust. Cut surface reveals a light gray interior
Petrography: Main minerals are olivine, pyroxene (with typical grain size 100 μm), plagioclase (to 200 μm). The texture is recrystallized with triple junctions and lobate grains. Rare relict chondrules. Plagioclase is found as euhedral grains and as veins between the other silicates. Ca-phosphates to 200 μm. Chromite to 50 μm. Metal as small blebs or elongated grains in the olivine.
Geochemistry: Olivine Fa 32.0±0.4 (N=4). Orthopyroxene Fs26.4±0.2 Wo1.9±0.5 (N=3). Plagioclase An10.4Or5.1 (N=3). Chromite Cr#=0.88. Magnetic susceptibility log χ =3.55 (χ in 10-9 m3/kg).
Classification: LL7 based on texture, Ca content of orthopyroxene, and plagioclase size. Weathering grade W1.
Specimens: 6.8 g and a polished section in CEREGE. Main mass with Jean Redelsperger
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.
The Bassikounou meteorite, is a meteorite of type H5, its fall was observed on October 16, 2006 near the locality of Bassikounou, in Mauritania, near the border with Mali.
Its ellipse of fall is 8 km long and its total known mass is 29.56 kg.
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.
