Writeup from MB 106:

El Boludo        23.01978°N, 99.90917°W

Tamaulipas, Mexico

Find: 2013

Classification: Ordinary chondrite (H5)

History: Numerous fragments and several whole stones, totaling 19.62 kg, were found by an American prospector, Greg Bruce, and his hunting partners in 2013 in Sonora, Mexico, while metal detecting for gold nuggets. The first piece (and the largest), a complete individual weighing 2396 g, was found on the surface in a sandy area on the eastern side of a large dry wash, a few kilometers northwest of the town of El Boludo. A search with metal detectors of the surrounding area produced numerous additional fragments and a few smaller whole stones. All known pieces were purchased by Aerolite Meteorites.

Physical characteristics: Deposit sample saw cut reveals relatively small chondrules and abundant opaque grains set in a dark brown groundmass.

Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows numerous equilibrated chondrules; plagioclase grains up to ~50 μm.

Geochemistry: (C. Agee, UNM) Olivine Fa19.3±0.3, Fe/Mn=40±1, n=9; low-Ca pyroxene Fs17.1±0.5Wo1.1±0.1, Fe/Mn=24±1, n=10.

Classification: Ordinary chondrite (H5)

Specimens: 22 g including a probe mount on deposit at UNM, Aerolite Meteorites holds the main mass.
