Miller Range 07006 (Mil 07006)

Field No.: 17961
Dimensions (cm): 1.5 x 1.0 x 0.75
Mass: 1.368 g (1 piece)

Meteorite Type: Lunar Basaltic Breccia

Macroscopic Description: Kathleen McBride: The exterior has no fusion crust and consists of a black matrix with visible clasts. The interior is a black matrix with gray, tan and white clasts.

Thin Section (,3) Description: Tim McCoy, Linda Welzenbach, Cari Corrigan and Rhiannon Mayne. The section shows a groundmass of comminuted pyroxene and plagioclase (up to 0.5 mm) with fine- to coarse-grained basaltic clasts ranging up to 2.5 mm. The matrix is extremely fine-grained and shock-darkened and melted in places. The pyroxene compositions range from Fs53Wo7 to Fs28Wo41 with a range of intermediate compositions. Plagioclase is An96. Olivine is Fa41-52. This meteorite is a basaltic lunar breccia, probably a regolith breccia. Fe/Mn ratio is 38-57.

Randy Says…

Compositionally, MIL 07006 is a basalt-bearing (but not basaltic) feldspathic lunar meteorite. It is compositionally and texturally identical to Yamato 791197, collected 2500 km away on the other side of Antarctica.
