Ordinary Chondrite, shocked (L6; S4; W0)
Fell, 31 March 1963; 45.76 kg

Just over 3 week after a fireball and detonations, fragments of the Peace River meteorite were recovered after much of the snow had melted. The meteorite is particularly interesting because it contains ringwoodite and wadsleyite (two high-pressure polymorphs of olivine) and majorite (a high-pressure polymorph of orthopyroxene).

The meteorite is today classified as an L6 chondrite, a member of the low iron geochemical group of ordinary chondrites. When recovered it was classified as a hypersthene-olivine chondrite utilizing more explicitly mineralogical criteria than is current practice.
