Fennoscandia

Perhaps I should share some general geological information about my part of the world.

Sweden and the Scandinavian peninsula was formed geologically from the continent of ”Baltica” which today is called the Baltic Shield or the Fennoscandian Shield. It consists of today’s Sweden, Finland, Norway, Northwestern Russia and parts of the Baltic Sea (not Denmark geologically). The Baltic Shield has a maximum age of about 3.1 Ga, but most parts of Sweden is formed on 2-1.5 Ga old granits and gneiss. In general its older to the north east than to the south west. Many parts of today’s mainland of the south east, like Skåne (Scania), the province where I live, is younger and formed of sedimentary deposits. But the Baltic shield is still below the sediments even here, some 2-3 kilometers and can be seen at some horst formations, especially along the Tornqvist zone. Scandinavia has a quite a variation of landscapes, both because of the differences in geology, but mostly due to the geographic distances. Some parts of the north have a arctic climate almost (Like Canada or Alaska). And here in the south there is a temperate climate. Probably the same as you might find around Boston or New York. The same temperate climate goes for Denmark, wich geologically consists only of sedimentary rocks and therefore technically isn’t a part of the Baltic Shield. Picture below of Baltic Shield.

 

The mountain range of Sweden and Norway is called the Scandinavian Mountains (“Skanderna” in swe.). It’s actually related to the Appalachian mountains since both belong to the Caledonian orogeny. Back in the days (450 Ma) they were connected before the Atlantic Ocean was formed. Picture below of Scandinavian mountains.

 

Picture below is Padjelanta national reserve in the north of Sweden. Typical view of the mountain landscape during summer.

 

Picture below is of Sarek National reserve in the north of Sweden. 

Pictures below shows parts of the Norwegian costal landscapes with their Fjords. Insanely beautiful if you ask me. Perhaps some of the most beautiful types of landscapes in the world. One could easily make an entire blog about the Norwegian fjords.

  1. I have to admit, I am jealouse for that landscape! ;-)
