Writeup from MB 106:

Quitovac        31.426°N, 112.696°W

Sonora, Mexico

Find: 12 Oct 2017

Classification: Ordinary chondrite (L5)

History: A team searching for gold with metal detectors near the village of Quitovac, Mexico, found five stones buried at shallow depth. All stones were subsequently acquired by Jason Phillips.

Physical characteristics: The stones (total weight 9112 g) are an overall reddish-brown color. Partial coatings that may represent weathered fusion crust are present on some of them, and interiors exhibit some fresh metal.

Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed of clasts with sparse chondrules in a recrystallized matrix containing altered metal, merrillite and chlorapatite.

Geochemistry: Olivine (Fa24.9-26.4, N = 3), orthopyroxene (Fs21.0-23.4Wo1.8-1.4, N = 3),clinopyroxene (Fs8.5-8.7Wo43.9-43.8). Magnetic susceptibility log χ (× 10-9 m3/kg)=4.54.

Classification: Ordinary chondrite (L5 breccia).

Specimens: 51 g including one polished thin section at UWB; remainder with Mr. J. Phillips.
