A large igneous province in the Arctic
The Sverdrup Basin Magmatic Province is a
large igneous province located on
Axel Heiberg Island and
Ellesmere Island,
Nunavut, Canada near the
rifted margin of the
Arctic Ocean at the end of
Alpha Ridge.
[1]
With an area of 550,110 km2, the Sverdrup Basin Magmatic Province forms part of the larger
High Arctic Large Igneous Province
[2]
[3] and consists of
flood basalts,
dikes and
sills
[4] which form two volcanic formations called the
Ellesmere Island Volcanics and
Strand Fiord Formation.
The flood basalt lava flows are similar to those of the
Columbia River Basalt Group in the
U.S. states of
Washington,
Oregon and
Idaho.
