Bedrock geology map of Jan Mayen (NP_J250_Geologi)

This is a bedrock geological map of Jan Mayen distributed as vector files, a georeferenced raster and a related non-spatial lithostratigraphy table. The map was compiled by W.K. Dallmann and published in Gabrielsen et al. (1997). A version was also published in Dallmann (2014), and the geology of this current edition is equivalent to that publication. The compilation was based on Imsland (1978), Roberts and Hawkins (1965) and Siggerud (1972, 1986) References: Dallmann, W. (2014). Geological map of Svalbard (1:750000).
