H6 chondrite, shock stage S1, weathering grade W0
The find site is located at the southern end of an extended, SE-NW oriented moraine being exposed on the surface of an ice depression between two nunataks (Delisle et al., 2015).
The meteorite is a stone partly covered by a thick fractured black fusion crust. The fine-grained gray matrix exposed on a cut surface is metal-rich with only minor staining along cracks. Chondrules are not visible at sight. The meteorite exhibits a strongly recrystallized texture under a microscope. Chondrules exhibiting well-delineated outlines are lacking and only a few relic chondrules are present. Twinned clinopyroxene is absent. The apparent diametre of plagioclase crystals is > 50 μm. Sharp optical extinction of olivine indicates that the meteorite is unshocked. Weathering effects are restricted to minor limonitic staining.
