Writeup from MB 102:

Yucca 029        34.787°N, 114.248°W

Mohave County, Arizona, USA

Found: 2011 Dec 14

Classification: Ordinary chondrite (H3)

History: Found by Jim Wooddell on Dec. 14, 2011, while he was prospecting for meteorites.

Physical characteristics: A single stone with glossy, weathered fusion crust (60.4 g).

Petrography: (A. Irving and S. Kuehner, UWS) Unequilibrated specimen composed of small (0.2-0.5 mm), well-formed chondrules in a fine-grained matrix rich in altered kamacite. Most chondrules contain relatively ferroan mafic silicates, but some are very magnesian. Composed of olivine, orthopyroxene, clinopyroxene, sodic plagioclase, chromite, troilite, altered kamacite, and merrillite.

Geochemistry: Olivine (Fa1.5-33.1, n = 9; Cr2O3 in ferroan olivine = 0.02-0.09 wt.%, n = 7), orthopyroxene (Fs0.9-17.5Wo0.8-1.1), subcalcic augite (Fs13.3Wo31.8).

Classification: Ordinary chondrite (H3.6). Subtype estimated from histograms of Cr2O3 distribution in ferroan olivine given in Figure 4 of Grossman and Brearley (2005).

Specimens: The main mass (46 g) is at ASU; 10 g and one polished thin section are at UWB. The remaining material is held by Mr. J. Wooddell.
