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...

Geologic interpretation of an aeromagnetic map of the west-central Columbia Plateau, Washington and Oregon Geologic interpretation of an aeromagnetic map of the west-central Columbia Plateau, Washington and Oregon
A low altitude, total intensity aeromagnetic map of the ?west-central Columbia Plateau, underlain principally by the Yakima Basalt,. shows Positive and negative anomalies that stand out from a moderate intensity .background reflecting .interbedded flows of normal and reversed magnetic polarity. One set of anomalies is related to anticlinal ridges, nother follows the traces of known or...
