Tank class=\"MBIndent\">Arizona, United States

Find: 2010

Classification: Ordinary chondrite (L6)

History: In 2010, Mr. Joe King found ten meteorite fragments while he was prospecting in the vicinity of the Golden Harp Mine, in the Tank Mountains between Yuma and Gila Bend, Arizona. The fragments, with a total mass of 8.05 kg, range from a few grams to several kg; the pieces fit together.

Physical characteristics: The pieces are orange-stained. Remnant fusion crust visible. Stone is angular with a few broad regmaglypts. Sawn surface is orange stained, showing an even distribution of small metal grains, to 1 mm, and a few discernible chondrules to 2 mm. A few thin shock veins traverse the slice.

Petrography: (L. Garvie, ASU) Electron microscopic examination of a polished thin section shows few recognizable chondrules. Olivine shows well developed PDFs and mosaicism. Kamacite shocked showing indistinct Neumann bands. Troilite grains single crystal, some polycrystalline. Plagioclase common and to 400 microns. Accessory chromite, Cl-apatite, and merrillite. Chromite extensively fractured. Troilite ~50% altered and kamacite ~25% altered to terrestrial oxides.

Geochemistry: (K. Domanik, UAz) Olivine Fa25.2±0.5, Fe/Mn=47±3, n=21, low-Ca pyroxene Fs21.3±0.9Wo1.7±0.3, Fe/Mn=29±2, n=22, augite Fs7.5±0.5Wo45.6±0.6, Fe/Mn=25±1, n=2, plagioclase Ab83.9±0.5An10.0±0.2Or6.1±0.4, n=5, large kamacite grains with 6.39 wt% Ni±0.36, n=10.
