New K-Ar ages for calculating end-of-shield extrusion rates at West Maui volcano, Hawaiian island chain New K-Ar ages for calculating end-of-shield extrusion rates at West Maui volcano, Hawaiian island chain
Thirty-seven new K–Ar ages from West Maui volcano, Hawai‘i, are used to define the waning stages of shield growth and a brief episode of postshield volcanism. All but two samples from shield-stage strata have reversed polarity magnetization, so conceivably the exposed shield is not much older than the Olduvai Normal-Polarity subchron, or about 1.8 Ma. The oldest ages obtained are in the...

Drag-out effect of piezomagnetic signals due to a borehole: The Mogi source as an example Drag-out effect of piezomagnetic signals due to a borehole: The Mogi source as an example
We show that using borehole measurements in tectonomagnetic experiments allows enhancement of the observed signals. New magnetic dipoles, which vary with stress changes from mechanical sources, are produced on the walls of the borehole. We evaluate such an effect quantitatively. First we formulate a general expression for the borehole effect due to any arbitrary source models. This is...
