FIRE 2 interpretation Interpretation

VSA Author: Taija Torvela
Date Created: 2010-01-12

Interpretation by Nironen et al. (2006). The FIRE 2 (and 2A) deep seismic reflection profiles were designed to study the relationships between the arc complexes of western and southern Finland and their internal structures (see docs & links for a location map). FIRE 2 begins in the central part of the arc complex of western Finland in the north, within the Central Finland Granitoid Complex. Further south the profile crosses the boundary between the arc complexes of western and southern Finland when it reaches the Tampere and Pirkanmaa belts. In its southernmost parts, the profile reaches Häme belt, another part of the southern Finland arc complex. The profile also has an east-west running side track within the Häme belt. The surface geology is correlated with the upper crustal (0-8 km) reflection properties in this interpretation, the overview of which is presented here. For details, see Nironen et al. (in: Kukkonen, Ilmo T. & Lahtinen, Raimo (eds.) 2006. Finnish Reflection Experiment FIRE 2001-2005. Geological Survey of Finland, Special Paper 43, 247 p., 15 apps.
