Geological Information

The geological setting is generally a prerequisite for a good understanding of the ground conditions in the project area. Often a general geological map exists in scale between 1: 50,000 and 1:100,000.  For large projects, a separate or additional geological mapping is often conducted.  A wrongly geological base may cause wrong interpretations as e.g.as described in the paper by Winter et al, 1994 and hence strongly influence on the construction of the project.

You will find a geological timescale here and here (/files/geo_timescale.pdf) and in website
http://www.stratigraphy.org/ICSchart/ChronostratChart2014-10.pdf 
(note that Tertiary has been changed into Paleogene and Neogene)

More on geological times can be found on International Commission on Stratigraphy

In addition you can find a simple overview of the geological history in Norway 
and a short introduction to rockmass composition.
