Comments
Chondrule abundance ~80%; chondrule mean diameter ~0.8 mm; metal abundance ~4%; fayalite mol% in olivine ranges Fa3-35, ferrosilite mol% in enstatite ranges Fs0-2; weak mosaicism along with planar deformation features and planar fracturing indicates shock stage S4, according to Stöffler et al. (1991); metal grains are sometimes rimmed by secondary oxides indicating a terrestrial weathering level W1, according to Wlotzka (1993).
