Abstract
An active source electrical conductivity sounding was carried out near the East Pacific Rise at 21°N. The average electrical conductivity from 2 km beneath the seafloor into the upper mantle was found to be about 0.004 S/m. There is no evidence of fully molten magma at a distance of 7 km from the spreading axis. The inferred conductivity with depth of the crustal rock is consistent with Brace’s model of connected, seawater filled pores in rocks heated from beneath.This publication has 14 references indexed in Scilit:
