The Springwater meteorite is a stony-iron pallasite, found near Springwater, Saskatchewan in 1931. ^[1][2] At that time the find consisted of three large masses (38.6 kilograms (85 lb), 18.6 kilograms (41 lb) and 10.6 kilograms (23 lb). Other fragments have been found recently, including a 53 kilograms (117 lb) individual in 2009 that is now in the Royal Ontario Museum.^[3]

Thirty percent of the meteorite is the iron-rich metallic phases kamacite and taenite, with the rest mostly made up of olivine. There are minor amounts of other minerals, including several phosphates such as farringtonite (Mg₃(PO₄)₂) and stanfieldite (Ca₄(Mg,Fe)₅(PO₄)₆) and merrillite (a member of the whitlockite group).
