Iso-Naakkima, a circular structure filled with Neoproterozoic sediments, Pieksämäki, southeastern Finland

A circular Bouguer gravity anomaly with a minimum of -4.0 mGal and half amplitude width of 2 km was recognized at Lake Iso-Naakkima (62°11'N, 27°09'E), southeastern Finland. The gravity low is associated with subdued aeromagnetic signature and notable airborne and ground electromagnetic an...
