Proposal that convective forces cause the extrusion of molten rock
near oceanic ridges
, and that the magnetite contained in such a relatively fluid medium is polarized during cooling by the earth’s current magnetic orientation
, thus explaining the deflections and deviations from the present alignment
that can be observed
in older rocks
. Proposed in 1963 by British geographers Drummond Matthews (1931-) and F. J. Vine (1939-88), who
acknowledged earlier contributions by Arthur Holmes (1890-1965) and Alfred Wegener.
