NWA 10668, Marbled H4 Chondrite, Micromount


NWA 10668 was recovered from the Saharan Desert of Morocco in 2015. It was classified by Dr. Tony Irving at UWS. Lab analysis showed the meteorite to be an H4 chondrite with moderate shock and weathering (S2/W2). The matrix shows two lithologies, one a light cream color and the other a darker brown. The lighter colored portions have more plentiful metal flecks, while the darker lithology is metal-poor. The classifier stated that the two "lithologies" are actually the result of uneven weathering, and that this is not an example of "dual lithology" in the technical sense. Tiny chondrules are scattered throughout the matrix.

There is an interesting story behind this meteorite : this meteorite was found by a nomad in the remote desert. He recognized it as a meteorite and took it into the nearby town of Laayoune. He then traded the stone to a merchant in exchange for lodging and food. That merchant heard that an American meteorite hunter was in town, so he subsequently sold it to the hunter who brought it back to the United States.
