  • Tectonics of the East Pacific Rise, 5⁰ to 12⁰S

    Creator:
    Rea, David K.
    Abstract:
    The portion of the East Pacific Rise (EPR) between 5° and 12°S can be subdivided into three areas by fracture zones that offset the rise axis at about 6.5°S and 9°S. In all three regions, the spreading axis of the EPR is defined by a topographic block 300 to 350...

  • The relationship between sedimentation rate and total organic carbon content in ancient marine sediments

    Creator:
    Ibach, Lynne E. Johnson
    Abstract:
    Sedimentation rate could become a new exploration tool for evaluating the source rock potential of sedimentary basins in frontier regions. Petroleum source rocks are defined on the basis of total organic carbon by weight percent. An analysis of Deep Sea Drilling Project (DSDP) cores indicates that there exists quantitative relationships...

  • Sediments and tectonics of the Gorda-Juan de Fuca plate

    Creator:
    Phipps, James B.
    Abstract:
    Cores taken from the ridge areas of the Gorda-Juan de Fuca plate have a sedimentation rate that is appropriate for the study of late Quaternary stratigraphy. An analysis of the clay and silt mineralogy of the cores using X-ray diffraction methods and by noting changes in the foraminiferan-radiolarian abundances in...
