中文摘要
以前的磁性地层学工作已经(1)确定了上部 奥杜威湖磁层的下边界 南部死亡谷的沉积物,(2)发现了类似的边界 可能是古马尼湖的哈拉米略河, 巴斯托在莫哈韦沙漠,(3)找到了什么可能是 文图拉皮科组的猛犸和Kaena事件 盆地 PI将对这些反转层位进行采样, 分辨率来确定它们的时间,化学和地磁 特色 现场的高保真记录是存在的, 显然包括长期变化和地磁反转。
英文摘要
Previous magnetostratigraphic work has (1) located the upper and lower boundaries of the Olduvai magnetic Chron in lake sediments from Southern Death Valley, (2) found similar boundaries of what is probably the Jaramillo Chron in ancient lake Manix near Barstow in the Mojave desert, and (3) located what may be the Mammoth and Kaena events in the Pico formation of the Ventura Basin. The PI will sample these reversal horizons in high resolution to determine their temporal, chemical,a nd geomagnetic characteristics. High-fidelity records of the field are present, apparently including secular variations and geomagnetic reversals.
