| 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 Description (,3) - Tim McCoy, Linda Welzenbach, Cari Corrigan, 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. | |
| Reclassification Notes (AMN 33,1) | |
| Original classification in AMN 31, no. 2 as a lunar basaltic breccia, but additional studies of more thin sections have revealed a predominance of feldspathic material over basaltic ([1] Korotev et al., 2009; [2] Liu, Y. et al., 2009). This is also reflected in the bulk composition which has high Al2O3 like other feldspathic regolith breccia ([18] Korotev et al., 2009). MIL 07006 is reclassified as a lunar anorthositic regolith breccia. References:
