Tuxtuac, Zacatecas, Mexico
Observed fall October 16, 1975, but first fragments not located for several years.
Olivine-hypersthene Chondrite, Amphoterite LL5, 196g
Tuxtuac is an unusual LL group chondrite because it lacks veining and brecciation features. Metal iron occurs within the meteorite as small angular grains associated with troilite. Chondrules are clearly defined and come in several varieties with colors ranging from dark brown to tan.
This specimen has a fusion crust with regmaglypts, fractured surface discolored from the heat, and a beautiful polished surface.
