Abbreviation: STG 07016
Observed fall: no

Coordinates (Meteoritical Bulletin 102): 72°19.849' S, 16°5.266' E
Recovered weight: 1.94 g
L6 chondrite, shock stage S3, weathering grade W1
The find site is near an ice rise loosely covered with rock fragments (Delisle et al., 2015).
The meteorite is a small fully encrusted stone with a black fusion crust. The cut surface exhibits a few metal flakes and has minor rust. Chondrules are not visible at sight. The meteorite exhibits under a microscope a strongly recrystallised texture. Well-defined chondrules are lacking and only a few relic chondrules are discernible. Twinned clinopyroxene is absent. The apparent diametre of plagioclase crystals is > 50 μm. Undulatory extinction of olivine and pyroxene, and the presence of planar fractures in olivine indicate that the meteorite is weakly shocked. Despite intense limonitic staining, oxide rims around metal and oxide veins are present in minor quantities.
