    In:  Supplement to: von Herzen, Richard P; Francis, T J G; Becker, Keir (1983): In situ large-scale electrical resistivity of ocean crust, Hole 504B. In: Cann, JR; Langseth, MG; Honnorez, J; Von Herzen, RP; White, SM; et al. (eds.), Initial Reports of the Deep Sea Drilling Project (U.S. Govt. Printing Office), 69, 237-244, https://doi.org/10.2973/dsdp.proc.69.106.1983

    Description: The achievement of deep penetration (562 m) of seafloor basalts at Hole 504B, near the Costa Rica Rift (1°13.63'N, 83°43.81'W), on DSDP Legs 69 and 70 presented a rare opportunity to examine the structure of young (6 m.y.) oceanic crust. In addition to the recovery of samples for laboratory studies, an extensive suite of downhole logs and experiments was carried out at this site, for two main purposes: (1) to allow reliable deductions about the nature of the entire section of penetrated crust, because recovery of samples was far from complete (-25%); (2) to probe the physical state of rock around the drilled hole on a scale of tens of meters to kilometers. Information on the latter large-scale phenomena at Hole 504B were provided mainly by the oblique seismic experiment, utilizing a bore-hole seismometer (Stephen 1983), and by the large-scale-electrical- resistivity experiment described below.

    Notes: [Auszug] In situ electrical resistivity was measured in DSDP Hole 504B to a depth of 1,013 m into oceanic basement. Apparent resistivities are about 10 Ω m in about 600 m of pillow lavas, sharply increasing to nearly 1,000 Ω m in the underlying dykes. Bulk porosities calculated from ...

    Notes: [Auszug] Different magnitude-frequency plots of rift and fracture zone earthquakes for both body and surface wave magnitudes indicate source rather than propagation effects as the cause. These could be differences either in the type of faulting between rift and fracture zone, or in the properties of the ...

    Notes: [Auszug] My suggestion that sediments might undergo periodic liquefaction in the vicinity of earthquakes does not rest entirely on the interpretation of seismic reflexion profiles.

    Notes: [Auszug] The individual thermal behaviour of the components of a sediment is straightforward and well understood. The pressure-volume-temperature relations for seawater differ very little from those for pure water3. The specific volume of pure water as a function of temperature and pressure has been ...

    Notes: Abstract Electrical resistivity measurements of the sea bed have been made from the submersible Cyana at four locations on a seamount close to the axis of the East Pacific Rise. Two of the sites were on a major sulpide deposit close to the top of the seamount, and the other two on pillow basalts near its base. The resistivity of the pillow-lava terrain was found to be about forty times greater than that of the sea water, in good agreement with downhole logging measurements in DSDP drill holes. The resistivity of the sulphide bottom was one to two orders of magnitude less than that of the pillow basalts. At one site the sea bed was almost twice as conductive as the overlying sea water and the deposit at this location is estimated to be about 9 m thick. Self-potentials of up to 10 mV, measured between a pair of electrodes 10 m apart, were associated with the sulphide deposit but were undetectable (i.e.≤0.1 mV) on the pillow basalts. The largest SP was associated with the most conductive sea bed, i.e. with the greatest concentration of sulphides.
