Metal and sulfide occur as spot of a few mm to a few tenths of mm. Conspicuous signs of oxydation.
Mineralogy: olivines Fo 74 ±2 (68-86), pyroxenes Mg#77±5 (68-86). Numerous clasts of small size (a few mm or less) some of which dark and nearly opaque others sub-opaques or well cristallized without matrix with broken chondrules some of small size and made up of matrix. Typical porphyric chondrules, a few barred chondrules, sometimes broken. Some devitrified partially vitrous. Metal and sulfides partly oxydized.
