  • Paleomagnetism and secular variation of Easter Island basalts

    Creator:
    Isaacson, Laurie Brown
    Abstract:
    The paleomagnetic history of the volcanic rocks of Easter Island was investigated using standard paleomagnetic techniques. The remanent magnetization of 673 specimens from the three volcanic episodes recognized on the island were measured using a spinner magnetometer. Inclinations, declinations and virtual geomagnetic poles were calculated for each flow. The majority...
