Writeup from MB 109:

Tungsten Mountain 073 (TM 073)        39°40.7732’N, 117°37.7552’W

Nevada, United States

Find: 5 Aug 2001

Classification: Ordinary chondrite (H5)

History: While conducting meteorite recovery on a dry-lake in Edwards Creek Valley, Robert Verish found this stone fragment on 2001-08-05

Physical characteristics: A single 28.5 g stony fragment, pyrimidal in shape (40 × 30 × 23 mm) having dark-brown, hackly exterior with some black patina. One side is covered in a patchy, rough-surfaced relict fusion -crust. Cut surface reveals many small metal-grains and small chondrules in a light-brown matrix.

Petrography: (D. Sheikh, FSU) Low chondrule abundance (900-1200 µm, n=3). Sample is composed of olivine, low-ca pyroxene, recrystallized plagioclase (average size 8±2 µm), troilite, Fe-Ni metal, Fe-oxides, and chromite.

Geochemistry: Olivine (Fa19.3±0.5, n=9), Low-Ca Pyroxene (Fs16.8±0.7Wo1.2±0.2, n=20).

Classification: Ordinary Chondrite (H5)

Specimens: 26.2 g at UCLA; main mass with Verish.
