Geological map of James Ross Island. I. James Ross Island volcanic group

Smellie, J.L.; Johnson, J.S.; Nelson, A.E.. 2013 Geological map of James Ross Island. I. James Ross Island volcanic group. British Antarctic Survey GEOMAP 2. Cambridge, British Antarctic Survey.

This single-sided geological map covers James Ross Island of the north-eastern Antarctic Peninsula with the map showing the volcanic rocks of the James Ross Island Volcanic Group (JRIVG). The geology of James Ross Island is dominated by the Miocene to Holocene JRIVG, which overlies a local basement composed of > 5 km of Cretaceous to Eocene marine sedimentary strata. The JRIVG is the largest Neogene volcanic field in the Antarctic Peninsula region and extends over 7000 km². It comprises a major shield volcano (Mount Haddington) and numerous monogenetic flank and satellite volcanoes.

The map includes a geological cross section across the central part of the island and a log of volcanic sequences across the island with correlations established from geochronology.
