Thermal and rheological structures along the seismic POLAR profile in the northern Fennoscandian Shield
Terra Nova, 25, 2–12, 2013 Abstract Extensive study is carried out to resolve the detailed lithospheric thermal and rheological structures of the seismic profile POLAR in the northern Fennoscandian Shield. The constructed 2‐D models are based on the latest seismic velocity models, material parameter...

The constructed 2‐D models are based on the latest seismic velocity models, material parameters and measured heat flow (HF) values.
