An Electrical Model For The SubIcelandic Crust

Active Resistivity And Magnetotelluric Experiments In Southwest Iceland Suggest Typical Resistivities For The Crust Of 10 To 100 Ohm-M. These How Crustal Resistivities Are Compared With Calculations On The Expected Resistivity Of Fluid-Saturated Crustal Rocks For Plausible Ranges Of Temperature, Pore-Pressure, And Water Chemistry. The Comparison Of The Synthetic Models With Actual Field Data Suggests: (1) The Suppression Of Resistivity At Shallow Depth Is Caused By Regional Hydrothermal Activity. (2) Appreciable Effects From Water Are Obtained From Depths To 8 Or 10 Km. (3) Below 10 Km The Effects From Conduction Along Electrolytic Paths Are Probably Dominated By Conduction In The Solid Rock Itself. Egi Reference Number Gl03496
