Paleomagnetism of Rapidly Deposited Hominid Tool-Bearing Sediments in the Northern Dead Sea Rift

96-14275 Levi PI建议从以色列的Erk-el-Ahmar地层中获得Matuyama古磁场，方向和相对古强度的详细记录，该地层包含非洲以外最古老的已知原始人工具承载地层。 这是一项对快速沉积的湖相沉积物进行的古地磁初步研究，可望提供松山地磁场的高分辨率记录，它适用于：比较极性间隔的长期变化和相对古强度，考察同一地点连续极性转换期间的场行为，研究地磁场的变化趋势。以及测试最近提出的跨越反转边界的强度不对称性的假设。 PI还假设，详细的磁性地层学将有助于更好地了解原始人类从非洲迁移的时间和路径。 ***

96-14275 Levi The PI proposes to obtain a detailed record of the Matuyama paleomagnetic field, directions, and relative paleointensities, from the Erk-el-Ahmar Formaiton in Israel, which contains the oldest known hominid tool-bearing strata outside Africa. This is a pilot paleomagnetic study of rapidly-deposited lacustrine sediments which are expected to provide a high resolution record of the Matuyama geomagnetic field that is suitable for: comparing secular variation and relatiave paleointensity of polarity intervals; examining field behavior during successive polarity transitions at the same locality; and testing the recently proposed hypothesis of intensity asymmetry across reversal boundaries. The PI also postulates that the detailed magnetostratigraphy will contribute to an improved understanding of the timing and pathways of the original hominid migration from Africa. ***
