Red Dry Lake 079 (RdDL 079)        35°39.05’N, 114°1.66’W

Arizona, USA

Find: 2009

Classification: Ordinary chondrite (L5)

History: Found in 2009 by meteorite-hunter, John Wolfe, while visually searching the surface of the dry lake.

Physical characteristics: This meteorite is a well-rounded, nearly-whole individual stone. The exterior is dark, grayish-brown and is 90% covered with a 2 mm-thick, relict fusion-crust, which is smooth and has very little in the way of rust-spots. A cut surface shows the interior is half-tan and half-orange in color, with few distinct chondrules in a compact matrix with very low metal-grain content, and few troilite grains.

Petrography: (Daniel Sheikh, FSU) Chondrule boundaries blurred (700±100 µm, N=3). Recrystallized matrix with plagioclase (10-25 µm).

Geochemistry: Olivine, Fa22.6±0.9 (N=25); orthopyroxene, Fs19.4±0.9Wo2.5±0.7 (N=25).

Classification: Ordinary Chondrite (L5)

Specimens: 2.16 grams at UCLA; main mass with Verish.
