At the foothills of the Swedish Himalayas
In the depths of a mighty mountain range - 3D modelling of the frontal part of the Sveconorwegian orogen.
The bedrock in southwestern Sweden belongs to the so-called Sveconorwegian orogen. The present form and character is a result of a collision of two continental plates that occurred about one billion years ago. The collision between the two continents has similarities to the collision between the Indian and the Eurasian continents, which has given rise to the mighty Himalayas.
The one billion years old mountain chain, of which southwestern Sweden's bedrock is a part, is now heavily eroded, and the bedrock can be said to correspond to a deep section in today's Himalayas.
A simplified 3D model of the bedrock in the easternmost part of the eroded Sveconorwegian mountain range, in the area between Kristinehamn and Karlskoga, in southeastern Värmland has been constructed. The model is based primarily on SGU's geological and geophysical information within the map areas Karlskoga NW, SW, NE and SE.
The model is presented in a video clip that can be found on youtube. It also briefly presents the development of the bedrock in the area.
The model can also be viewed in a 3D-pdf, which can be rotated and where layers can be turned of and on.
3D PDF Instruction
If you are having any trouble with viewing the 3D PDF model file then the following tips may help.
- Download the pdf file to your computer- you will get a faster response when you open and manipulate the model.
- Open the PDF file by right-clicking with your mouse and select 'open with'.
- Open the file with Adobe Acrobat Reader (the 3D PDF works best with the free reader software rather than Adobe Acrobat Standard or higher versions).
- Look at the menu at the top of the screen: select View-, Show/Hide-, Navigation Panes-, Model Tree. You should then get a model tree menu on the left of your screen where you can set the visibility of the individual objects on and off.
- Deselecting the large object 'Quartz_monzodiorite_to_granite_TIB' in the tree menu will make everything else clearer.
- The most simple manipulation of the model is by left clicking on the screen and dragging with your mouse which will make the model rotate.
- Right clicking will bring up another list of options.
