Writeup from MB 110:

Arizona City        32°45’46.60"N, 111°37’12.16"W

Arizona, United States

Find: 1988

Classification: Ordinary chondrite (H4)

History: (C.B. Moore, ASU) Purchased from Mike Yeatts (formerly in the Department of Anthropology, ASU) who found the meteorite near the intersection of West Bataglia Dr. and North Toltec Rd ~4.8 km east of Arizona City while doing a field survey for a projected irrigation ditch.

Physical characteristics: Single 83.9 g squarish, fusion crusted meteorite. The fusion crust is largely orange stained. Interior of the stone is dark, with an abundance of chondrules, small troilite and metal grains to 1 mm.

Petrography: A petrographic thin section reveals an abundance of chondrules and mineral fragments hosted by an opaque iron-oxide stained matrix. Wide range of chondrule types (e.g., PP, PO, POP, BO, RP, GO, GP), which show a wide size range, with mean between 400 and 500 µm, though a 3 × 3 cm slice shows several chondrules in the 1 to 2.5 mm range. Reflected-light image shows ~70 % of the Fe-Ni metal and ~50 % of the sulfide weathered to Fe-oxides. Troilite is single crystal and lacks shock lamellae.

Geochemistry: (L. Garvie, ASU, K. Domanik, UofA) Fa19.0±0.2, range 18.7 to 19.3, FeO/MnO=35.2±1.7, N=20. low Ca pyroxene Fs16.4±0.2, range 16.0 to 16.8, Wo1.37±0.12, n=19. high Ca pyroxene Fs5.8±0.4Wo46.3±0.4, n=6.

Classification: H4, low shock, high weathering.

Specimens: 83.9 g at ASU
