Volcanic Basins

Volcanic basins are sedimentary basins with a significant amount of primary deposited volcanic rocks. The volcanic deposits and processes may have a major influence on the geology and petroleum prospectivity of sedimentary basins, including source rock maturation, fluid migration pathways, trap formation, and structural deformation.

VBPR is dedicated to research on volcanic basin processes in collaboration with leading universities. We have been closely involved in Physics of Geological Processes (PGP), a Norwegian Center of Excellence at the University of Oslo (2003-2013), and we have collaboration with e.g. the National Oceanography Center, Southamton, GEOMAR, and University of Tromsø.

Our main reserach effort is on magma-sediment interaction, petroleum geology of volcanic rifted margins, and seismic imaging and interpretation of volcanic complexes. However, our research interests spans from cold seeps ecology to paleoclimate and magmatic petrology.

 Research results are published in international journals and reports. See our comprehensive publication list for references.
 
Large Igneous Provinces (LIPs) and Volcanic Basins

LIPs are the surface manifestation of mantle melting processes commonly associated with thermal plumes. LIPs are divided into Continental Flood Basalts, Volcanic Rifted Margins, and Oceanic Plateaus and Ridges.

Volcanic basins are found along many of the world's prospective rifted margins, in particular in the north and south Atlantic ocean (gray ellipses on the map).

VBPR have conducted field work and offshore studies of LIPs in the NE Atlantic, W Greenland, Karoo, India, W Australia, Siberia, and South America.

Nature-cover300

VBPR participated in developing an early Eocene global warming theory related to emplacement of voluminous sill intrusions in organic-rich sedimentary basins (Svensen et al., 2004). The Nature cover shows the seismic imaging of sill and hydrothermal vent complexes in the Vøring Basin offshore mid-Norway.
