Springwater is a pallasite (PMG-an) found in Saskatchewan, Canada. In August of 1931, Harvey H. Nininger received the first of several masses of the Springwater meteorite from citizens of Springwater, Saskatchewan, which is approximately 100 miles west of the city of Saskatoon.

Northwest Africa 725 (NWA 725) is an acapulcoite achondrite found in Morocco. As defined by the Meteoritical Society, members of the acapulcoite-lodranite group of meteorites are equigranular primitive achondrites that show subchondritic compositions, with mineral assemblages similar to, but distinct from, ordinary chondrites. Acapulcoites are finer grained than lodranites and some rare members contain relict…
