Writeup from MB 106:

Nova 017

United States?

Find: unknown

Classification: Ordinary chondrite (H5)

History: A single specimen was handed down to the owner by his great aunt in the 1960s. Likely originated in the southwest US.

Physical characteristics: The ~7 cm-wide, equant specimen is mostly covered with a dark-brown fusion crust. Some red-brown oxidation is evident.

Petrography: (C. Herd, UAb) Cut surfaces reveal light and dark areas consistent with brecciation. Consists of well-delineated chondrules of a variety of textural types. Plagioclase grains are up to 20 μm across. Shock effects include minor veining. Weathering grade according to Zurfluh et al. (2016).

Geochemistry: (C. Herd, UAb) Data obtained by EMP examination of carbon-coated thin section: Olivine Fa19.0±0.3 (n=29); Low-Ca Pyroxene Fs16.8±0.9Wo1.1±0.1 (n=29). Two data points are consistent with a type L (Fs19.8), indicative of a polymict breccia.

Classification: Ordinary chondrite, H5, breccia. Petrologic type 5 based on well-delineated chondrules and plagioclase grain size (2-50 μm).

Specimens: Type specimen of 26.4 g, including one thin section, is at UAb. Main mass is with the owner.
