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.

The main mass, 101 grams is for sale, an exceptional piece!
SAH 99159 is an ordinary chondrite of type LL3, it was discovered in the Sahara in 1999 at the beginning of the prospection of meteorites in the deserts.
The slice offered for sale is very representative of ordinary chondrites with nice well defined and very colorful chondrules.
Ordinary chondrites are made of small balls called chondrules that have accumulated together.

A total of 1600 kg, ranging in mass from << 1 to 35,000 g, and a single 83 kg individual completely covered with regmaglyptes, were found in the Kamil impact crater in Egypt. This 45 m diameter crater was discovered by an Italian-Egyptian geophysical team in February 2009 and February 2010. Approximately 800 kg of the total mass observed in the field (including the regmaglypted individual) was recovered.
