Ilkonsaari island outcrops


The Ilkonsaari island consists of two rocky ridges running southeast-northwest which are connected by a soil area formed through deposition by waves. The soil area was formed in a bedrock fracture zone weathered deeper than the surrounding environment. The outcrops in the rocky areas of Ilkonsaari represent several different kinds of rock types, such as granodiorite, dike breccia, tonalite, and granite.
