Tule Valley Hardpan 007 (TVH 007) 38°59.629’N, 113°22.909’W Utah, USA Found: 2014 May 14 Classification: Enstatite chondrite (EL6) History: Found visually, partly exposed in dry lake hardpan by W. Wooddell, with J. Wooddell and D. Libszowski. Physical characteristics: Single stone. Irregular weathered exterior, dark brown. Dimensions 20 × 10.5 × 7.5 mm. Saw cut reveals numerous sub-millimeter metal grains set in a dark brown fine-grained groundmass. No visible chondrules. Petrography: (C. Agee, UNM) Microprobe and optical examination of a thin section shows silicates: 98% enstatite and 2% plagioclase; no chondrules observed in BSE or with petrographic microscope. Many enstatite grains in the size range 100-300 μm, bounded and crosscut by numerous metal/oxide veins. Abundant kamacite; taenite and troilite present. Geochemistry: (C. Agee and N. Muttik, UNM) Enstatite Fs0.6±0.3Wo1.3±0.0, n=22; plagioclase Ab80.9±0.9An14.5±0.7Or4.5±0.3, n=4; kamacite Si=1.25±0.03, Ni=6.09±0.14, (wt%), n=2; taenite Si=0.12, Ni=20.76, (wt%). Classification: Enstatite chondrite (EL6), weathering grade W2. Specimens: 1.6 g and thin section on deposit at UNM. Polished mount held by W. Wooddell. | ||||||||||||||||||||||||||||||||
