Sahara 97091 (EH3), found 1997, Sahara desert. See the meteoritic bulletin N° 82 http://www.lpi.usra.edu/meteor/metbull.php?code=22894 

 

Enstatite / EH3 / Sahara 97096, 97072, 97158

 

 

NAME: Sahara 97096 paired with the Sahara 97072, Sahara 97158, Sahara 97093, Sahara 97161, Sahara 97091, Sahara 97166

TYPE: EH3 S2 W1, enstatite chondrite, high-iron subgroup, unequilibrated


This is perhaps the most primitive EH3 chondrite found to date. It contains early nebular components, including well-defined, layered, silicate-, sulfide-, and metal-rich chondrules, FeO-rich silicates with broad compositional ranges, and refractory inclusions, and it has experienced very low degrees of thermal metamorphism.

 

The meteorite SAH97096, and its pairing group(included Sahara 97072, Sahara 97158, Sahara 97093, Sahara 97161, Sahara 97166), classified EH3 were found during one of our meteorites collecting in 1997 in the Sahara Desert. It can be classified among the most primitive enstatite chondrite comparable to Qingzhen and Parsa. It contains olivine chondrules and types II chondrules fragments. This meteorite has been described as a highly primitive EH3 chondrite that has retained primary accretional nebular features in the form of sulfide-metal rich chondrules.
