The results of numerous resistivity soundings from all parts of Iceland are analyzed. The resistivity and the P wave velocity of the uppermost kilometer in the crust show a strong correlation with the geological structure of Iceland. By estimating porosity from P wave velocity, Archie's law is found not to be valid in general. The temperature dependence of nine water‐saturated basaltic rock samples was investigated in a laboratory showing stronger temperature dependence than expected from pore fluid conduction. These two facts suggest that interface conduction is the most important conduction mechanism. A relation between bulk resistivity, fracture porosity, pore fluid resistivity, and temperature is established. Comparison of regional bulk resistivity with different zeolite zones shows that the resistivity is mainly a function of the maximum depth of burial of the lava pile, emphasizing the importance of clay minerals and zeolites for the measured bulk resistivity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
