Red Dry Lake 067 (RdDL 067) 35°39.521’N, 114°1.544’W Mohave, AZ, USA Found: 3 March 2009 Classification: Ordinary chondrite (L3.4) History: A single, black, fusion-crusted stone was found by Paul Desilets on March 3, 2009, on Red Dry Lake, Arizona. Physical characteristics: The 6.2-g stone displays dull, moderately weathered black fusion crust. Several large chondrules protrude from the stone. The interior of the stone is gray with minor iron-oxide staining. Petrography: (Laurence Garvie, ASU) The section shows a close-packed aggregate of chondrules and chondrule fragments to 2.2 mm. The matrix is dark with minor metal and troilite, which is sometimes concentrated at chondrule rims. Chondrules are dominated by granular, PO, POP, poikilitic pyroxene, and PP, with subordinate amounts of RP and BO. In addition, the section contains two 500 μm well-developed, purple (in PP transmitted light) glass chondrules, several chondrules with bleached rims, and a 500 μm metal-sulfide chondrule. Geochemistry: (Laurence Garvie, ASU) Microprobe analyses show olivine and pyroxene of variable compositions. Olivines Fa0.3-42.1, with a mean of 23.9 mol% (n=33). Cr2O3 shows a bimodal distribution with maxima at 0.02 and 0.08 wt%. Pyroxene Fs1.3-31.4 and Wo0.2-5.0. One PP chondrule contains small augite grains Fs20.95Wo30.05. Oxygen isotopes: (R. Tanaka and D. Rumble, Okayama University at Misasa), (mean of two replicates: δ17O = 3.77‰; δ18O = 5.48‰; Δ17O = 0.88‰). Classification: Ordinary chondrite, L3.4 Specimens: ASU holds 2.281 g (in three pieces), two thin sections and one polished stub. | ||||||||||||||||||||||||||||||||||||
