San Pedro de Urabá        8°16’44.39"N, 76°22’41.67"W

Antioquia, Colombia

Confirmed fall: 16 Feb 2017

Classification: Ordinary chondrite (L6)

History: At 5:30 pm local time on 16 February 2017, a large fireball with sonic booms was observed in northern Colombia. A meteorite subsequently impacted near Mr. Orlando Cuevas on the edge of a soccer field in San Pedro de Urabá, Turbo district, Antioquia State, Colombia. The event was widely reported in the local media, e.g., www.minuto30.com/fotos-en-zona-rural-de-turbo-aseguran-que-cayo-un-meteorito/340813/, which shows a picture of the 3768 g stone from the soccer field. Two other stones are known to have fallen, one much larger than the one that was collected in the soccer field, but their whereabouts are unknown. Michael Farmer acquired the 3768 g stone from Mr. Cuevas.

Physical characteristics: Single regmaglypted stone covered with matte black fusion crust. Interior is a light greenish-gray and friable. Cut surface shows poorly defined chondrules and even distribution of small metal/troilite grains. Only a single thin shock vein is visible.

Petrography: (L. Garvie, ASU) SEM observation of a polished mount shows scattered poorly defined chondrules (BO, RP, and PO) largely integrated with the matrix. All silicates heavily fractured. Feldspar grains typically >50 μm, with many around 100 to 200 μm. Troilite anhedral and dominantly single crystal to 400 μm. Rare anhedral Ca-Na-Mg phosphates to 60 μm. Chromite to 600 μm is anhedral to subhedral and heavily fractured. Three Fe-Ni metal types present: kamacite, dominantly single crystal (to 0.5 mm) with a frosty etch and weakly defined Neumann bands; tetrataenite, rare, commonly contiguous to kamacite; and, equant Ni-zoned grains with Ni-rich rims and dark-etched cores, some showing kamacite spindles. Native Cu is rare and occurs as <10 micron grains at kamacite/troilite boundary. Scattered and rare melt pockets to 60 μm.

Geochemistry: Olivine Fa25.1±0.3, FeO/MnO=47.6±1.8, n=9; low Ca pyroxene Fs21.4±1.2Wo1.5±0.2, FeO/MnO=28.4±1.3, n=10; Feldspars Or13.4±0.3Ab67.3±67.3±0.5, n=3 and Or5.4±0.1Ab84.4±0.02, n=2.

Classification: Ordinary chondrite L6, S3, W0

Specimens: 32 g at ASU. Main mass with MFarmer.
