Iceland GeoSurvey, ÍSOR, has published a new map entitled Geological Map of Central Iceland. This map is the fifth in the series of geological maps of Iceland´s volcanic zones in the scale of 1:100 000. Landsvirkjun and the Ministry of Environment and Natural Resources supported the work on this map.
The map shows four major central volcanoes with related postglacial lavas. Furthermore, lavas from the Langjökull/Hveravellir and Bárðarbunga volcanic systems (mostly outside the map) are presented. Main geothermal sites are indicated along with key tectonical features and main deglaciation structures of the area.
The maps is based on several larger scale maps created by ÍSOR and its forerunner, the National Energy Authority, for various customers. These maps were revised and redrawn using new data acquired in the field.
On the back of the map, 23 selected sites of interest are pointed out with descriptions.
The map is compiled by the geologists Árni Hjartarson, Ingibjörg Kaldal, Kristján Sæmundsson, Magnús Á. Sigurgeirsson and Skúli Víkingsson.
Cartography by Albert Þorbergsson and Guðrún Sigríður Jónsdóttir.
