Abstract
The Late Paleozoic and Mesozoic history of petroleum and coal basins in the Arctic and adjacent areas is investigated and compared with the history of plume magmatism in the same areas. The sedimentation rates in all discussed cases are proven to be the fastest (more than 100 m per 1 Myr) during rifting events. Other peaks of rapid deposition may be associated with collisional mountain growth and/or climate change.
