| Thin Section
(,5) Description - Tim McCoy and Linda Welzenbach |
| The section shows a groundmass of comminuted pyroxene and plagioclase (up to 0.5 mm) with fine- to coarse-grained basaltic clasts exceeding 2 mm. Pyroxene includes diogenite-like compositions of Fs27-29Wo2-3 and pigeonite of Fs43Wo9. Plagioclase is An80-85 and olivine is Fa37-38. A distinctive feature of this meteorite is patches of troilite that appear to have been melted, forming a web structure that encloses silicates. The meteorite is a howardite. |
