Writeup

Writeup from MB 106:

Sahara 99362

Sahara

Find: 1999

Classification: Ordinary chondrite (L5, melt breccia)

Petrography: The studied thin section consists of about 70 vol% of fine-grained melt lithology and ~30% of large shock-darkened L-chondrite clasts. Relict chondrules are visible within these large shock-darkened clasts, indicating the occurrence of metamorphosed fragments of about type 5/6. The melt lithology basically consists of a very fine-grained intergrowth of different phases and also contains abundant small fragments of the target rock as well as isolated metal-sulfide assemblages (often rounded). The metal shows only weak effects of terrestrial weathering (W1).

Geochemistry: Olivine from the fragments is Fa_24.3±0.3(n=5) and low-Ca pyroxene is Fs_20.1±0.3Wo_2.5±1.1(n=4).
