Compact endcut with two cut surfaces, of which one is polished, two broken surfaces and one large surface with original fusion crust. The latter shows light caliche deposits in cracks and cavities. Mount Tazerzait shows an extraordinary lithology. Contrary to most other ordinary chondrites, the material displays very little impact induced shock alteration and a relatively long cosmic exposure age. The most striking difference to common L5 chondrites, is an unusually high porosity of 12.6 percent, with a high amount of vugs in its matrix, often with euhedral to anhedral crystals that have formed in these interstitial pores.
