Iceland GeoSurvey (ÍSOR) has released an improved geological map of Southwest Iceland in the scale of 1:100 000. This is the second edition of the map, which was first published in 2010. In this version the geology has been updated and improved to reflect the new research in recent years. On the reverse of the map, 39 selected sites of interest are described, in both Icelandic and English.
The map is based on several maps in 1:20 000 – 1:50 000 produced by ÍSOR and its forerunner for various customers. With the aid og geological mapping the maps have been simplified and revised. The oldest features shown are 4 million years in Mt. Akrafjall, Western Iceland and the youngest are from the Reykjanes Peninsula being erupted in 1210-1240 AC. Altogether there are about 160 lava flows on the map.
This new edition is compiled by Kristján Sæmundsson, Magnús Á. Sigurgeirsson, Árni Hjartarson, Ingibjörg Kaldal and Sigurður Garðar Kristinsson.
Cartography by Guðrún Sigríður Jónsdóttir.
