Aubrey Hills        34°22.838’N, 114°10.023’W

Mohave County, Arizona, United States

Found: 23 Sept 2010

Classification: Ordinary chondrite (H6)

History: The meteorite was found by Myke Steighler while hunting for meteorites on alluvial flats southwest of Standard Wash, Lake Havasu City, Arizona. The meteorite was observed amongst desert-varnished stones.

Physical characteristics: Single, smooth, 560.8 g trapezoidal stone, remant fusion crusted. Interior shows two distinct zones: upper 3/4 is light-colored and shows minor weathering (W1), and bottom quarter (presumably embedded in the ground), heavily weathered (W4). Junction between fresh and weathered portions is sharp.

Petrography: (L. Garvie, ASU): The unweathered part is largely recrystallied, vuggy, with a few recognizable chondrules including BO, PP, and RP (mostly <1 mm). The studied section contains one large, 2.5 mm, barred-olivine chondrule, with the bars arranged in a pentagonal shape. The matrix minerals protruding into the vugs are often euhedral. Plagioclase and chromite abundant, to 300 μm. Kamacite (<1 mm) common, with rare plessite grains (<50 μm). Troilite grains untwinned and single crystal. Minor Cl-phosphate grains to 250 μm. Olivines show sharp optical extinction.

Geochemistry: Olivine Fa18.9±0.3 (range Fa18.4-19.4, n=12), FeO/MnO=39.9±2.7. Low Ca pyroxene Fs16.6±0.1Wo1.4±0.1, n=6. Augite Fs6.2-6.3Wo45.3, n=2. Feldspar An12.6Or5.0, n=1.

Classification: Ordinary chondrite (H6)

Specimens: 26.03 g, one polished section and probe mount at ASU. Main mass held by Myke Steighler of Lake Havasu City, AZ.
