Geological Maps

What is this data?

Geological maps show the age and type of Iceland’s bedrock and loose strata, along with various features that relate to the development of the island and its geology, such as craters, fracture zones, geothermal heat, fossils and dip.

The mapping of Iceland’s geology has been one of the IINH’s main activities from the time that Guðmundur Kjartansson published the first geological map of Iceland in 1962. The data used to compile geological maps comes from many different quarters, and the IINH has collaborated closely with other institutions in obtaining data. The IINH has prepared geological maps at various scales, of which 1:500 000 and 1:250 000 have been the most frequently used to date.

Where is it available ?

An overview of the maps in 1:250000 is available here and the metadata for the maps can be found here. To get the scanned version of the existing maps you have to contact the head of the Earth Science Institute.
