Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: April 1976 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: April 1976

Rise of a variable-viscosity fluid in a steadily spreading wedge-shaped conduit with accreting walls Rise of a variable-viscosity fluid in a steadily spreading wedge-shaped conduit with accreting walls

Relatively rigid plates making up the outer 50 to 100 km of the Earth are steadily separating from one another along narrow globe-circling zones of submarine volcanism, the oceanic spreading centers. Continuity requires that the viscous underlying material rise beneath spreading centers and accrete onto the steadily diverging plates. It is likely that during the rise the viscosity...
