Description

<jats:p><jats:bold>Abstract—</jats:bold> The Tuxtuac meteorite fell in Zacatecas state, Mexico, on 16 October 1975, at 1820 hours. Two partly crusted masses, weighing 1924 g and 2340 g, were recovered. The stone is an ordinary chondrite, LL5, with olivine Fa<jats:sub>30</jats:sub> and 19.22 weight % total iron. The silicates contain numerous voids and a froth‐like mesostasis is present within some chondrules. Metal phases present are kamacite (5.7–6.4% Ni, 6–7% Co) and high nickel metal (taenite 37–41% Ni, 1.7 ± 0.3% Co; tetrataenite 47–52% Ni, 0.8–1.4% Co). The stone is unusual for an LL‐group chondrite in that it exhibits neither large‐scale brecciation features nor dark veins.</jats:p>
