Tanezrouft  087

Algeria, East Tanezrouft

Found 2003 December 23

Ordinary chondrite (H5)

One 320 g stone, partially covered with a reddened fusion crust was found. Classification and mineralogy (M. Bourot-Denise, MNHNP): the stone is an H5 with a large clast of CO3 material comprising about 30% of the entire mass. Host lithology: olivine, Fa20.6 ± 0.2; low Ca pyroxene, Fs18.0 ± 0.3.; the chondritic texture is still clearly visible, with many chondrule relics. Shock stage S2, weathering grade W3. CO3 clast: it is much more altered, most metal grains are oxidized and silicates are reddened; chondrules are small (~100 µm) and set in a fine-grained matrix with abundant small sulfide grains. Opaque nodules comprise rusted metal, sulfide and magnetite. Estimated metamorphic grade between those of Colony and Kainsaz. Olivine, Fa1.6-32.6, mean Fa15.3±7.5, up to 0.4 wt% CaO; pyroxene, Fs2.0-18.4, mean Fs10.1±5.5. Specimens: type specimen 35.1 g, and one polished mount MNHNP; main mass with Annick Goueslain and Jean Luc Parodi.
