Geological Information

Published on February 14 2015

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 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
(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.

Important quotations are presented below from time to time:

”…..there is still no acceptable substitute for the field mapping and core logging carried out by an experienced engineering geologist.”
Evert Hoek, 1986.
