Saarijärvi is an impact structure mostly covered by a small lake by the same name. It is located about 40 km south from the town of Taivalkoski, Northern Ostrobothnia, Finland. The impact origin of the structure was confirmed in 1997 when poorly developed planar deformation features (PDFs) in quartz grains were found in drill-core samples obtained from the bottom of the structure by a mining company while searching for diamonds in the region. Later an amateur geologist Jarmo Moilanen discovered also shatter cones within the impact structure. Saarijärvi is the only currently accepted impact structure in Fennoscandian Shield formed in Archean granitoid basement complex.
