New gravity and magnetic anomaly maps for the Barents and Kara Sea region only allow mapping of tectonic features where the thick sedimentary cover is tectonically disturbed. Maps of sedimentary thickness and depth to top basement and the Moho differ between the western and eastern Barents Sea, although detailed thickness and depth estimates require calibration by seismic data. Internal plate boundaries created during the amalgamation of the Barents Sea region were not detected using potential field data.
Figures & Tables
The vast Arctic region contains nine proven petroleum provinces with giant resources but over half of the sedimentary basins are completely undrilled, making the region the last major frontier for conventional oil and gas exploration. This book provides a comprehensive overview of the geology and the petroleum potential of the Arctic. Nine papers offer a circum-Arctic perspective on the Phanerozoic tectonic and palaeogeographic evolution, the currently recognized sedimentary basins, the gravity and magnetic fields and, perhaps most importantly, the petroleum resources and yet-to-find potential of the basins. The remaining 41 papers provide data-rich, geological and geophysical analyses and individual oil and gas assessments of specific basins throughout the Arctic. These detailed and well illustrated studies cover the continental areas of Laurentia, Baltica and Siberia and the Arctic Ocean. Of special interest are the 13 papers providing new data and interpretations on the extensive, little known, but promising, basins of Russia.
A DVD is provided inside the back of the book, that contains PDFs of all papers plus all related Supplementary Publications.
