Writeup from AMN 29(2):
Sample No.: MIL 05029; MIL 05136
Location: Miller Range
Field No.: 18098; 18174
Dimensions (cm):   5.5x4.4x4.0; 2.5x2.0x1.0
Weight (g): 132.68; 8.308
Meteorite Type: L Chondrite (Impact Melt)


Macroscopic Description: Kathleen McBride and Cecilia Satterwhite
The exterior of 05029 has tiny black patches of fusion crust, the rest is a mottled gray with green crystals visible; 05136 has no fusion crust. The interior is a yellowish gray matrix with abundant green inclusions. There are some rusty areas.


Thin Section (,2) Description: Tim McCoy
The sections are so similar that a single description suffices. The meteorites consist of large (up to 4 mm) orthopyroxene grains with interstitial feldspar with both of these phases poikilitcally 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).
