Ryder Gletcher

Knud Rasmussen Land, North Greenland

Found 1988 or 1989

Ordinary chondrite (L5)

A stone of 5288 g was brought to the Natural History Museum Bern for investigation in August 2001. It had previously been shown to Dr. W.R. Danner at UBC Vancouver in 1995 as a meteorite from Greenland. The finder spotted the stone from low-flying aircraft on a north-flowing valley glacier at a surface altitude of approximately 1000 m. The stone is relatively unweathered, oriented and completely covered with a black fusion crust. Classification and mineralogy (E. Gnos, UBE; B. A. Hofmann, NMB): olivine Fa23.5±1.1 (22.5 by XRD); pyroxene, Fs20.8 Wo1.2 ; shock stage, S4; weathering grade, W1. Some areas are shock-blackened (troilite mobilisate on fractures). Specimens: type specimen: 21 g, Geological Museum Copenhagen, main mass (5199 g) with anonymous finder.
