Field measurements of apparent Curie temperatures in a cooling basaltic lava lake, Kilauea Iki, Hawaii Field measurements of apparent Curie temperatures in a cooling basaltic lava lake, Kilauea Iki, Hawaii
Magnetic susceptibility and temperature measurements have been made in two of three holes drilled in 1975 through the crust and into the still molten lens of tholeiitic basalt in Kilauea Iki lava lake (formed in 1959). The temperature above which magnetic susceptibility drops to zero—the apparent Curie temperature—is 540°C. at depths of 34.7‐35.9 m below the lake surface. These field...

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...
