Jdiriya 004 R3 #4 – 6,3 g

220,00

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.
