Mantle plumes: heat-flow near Iceland

Seafloor heat-flow near Iceland on the North American side of the Mid-Atlantic Ridge is comparable to that for oceanic lithosphere elsewhere, and thus shows no evidence for significantly higher temperatures associated with a mantle plume. Heat-flow is higher on the Eurasian plate than on the North A...

Description
Summary:Seafloor heat-flow near Iceland on the North American side of the Mid-Atlantic Ridge is comparable to that for oceanic lithosphere elsewhere, and thus shows no evidence for significantly higher temperatures associated with a mantle plume. Heat-flow is higher on the Eurasian plate than on the North American plate, an intriguing asymmetry opposite to that expected from models in which Iceland formed over a mantle plume.
