Writeup from AMN 30(1):
Sample No.: MIL 05155
Location: Miller Range
Field No.: 18048
Dimensions (cm):   5.0x4.0x2.0
Weight (g): 53.508
Meteorite Type: L Chondrite (Impact Melt)


Macroscopic Description: Kathleen McBride
Brown/black patches of fusion are on <5% of this meteorite's exterior. The interior matrix is coarse grained and tan to light green in color with visible olivine crystals.


Thin Section (,2) Description: Tim McCoy and Valerie Reynolds
The meteorite is paired with the MIL 05029 pairing group, the original description of which was: The meteorites consist of large (up to 4 mm) orthopyroxene grains with interstitial feldspar with both of these phases poikilitically enclosing 50-200 µm olivine grains. Minor metal and sulfide are present, with sulfide occasionally rimming metal. Silicates (olivine of Fa25, orthopyroxene of Fs21Wo4, plagioclase of An16Or3) are compositionally within the range of L chondrites. The meteorites are likely L ordinary chondrite impact melt rocks and similar in some respects to PAT 91501 (Mittlefehldt and Lindstrom, MAPS, 36, 439).
