Magnetic Field Excursions and Related Secular Variation During the Brunhes Epoch (0-780,000 YBP)

新的原始古农业结果第72段估计了整个布伦斯纪和布伦蒂I‘v 13布伦赫斯时代磁场漂移的长期变化模式。这是第一个允许在这样的时间间隔和时间间隔内定向观察长期变化的数据集！在远足和古迹的框架内考虑较少。对个别漂移记录的详细分析表明，有两种基本不同的漂移类型，一种是与正常长期变化密切相关的t\t~c，另一种类型则不认为cd是一种流产的反转。该项目将分析和确定PIVVIOLIS古地磁遗迹，并对Cleven Except和Fh(，III)连续的长期变化做出有选择的新的离散样本。

New initial paleornagrictic results froni ODP Leg 72 estimate the pattern of secular variation for the entire Brunhes Epoch and identi I'v 13 Brunhes-aged magnetic field excursions. This is the first data set that allows ~i directional look at secular variations over such a ]on - time interval and a! lows consideration within the framework of excursions and paleointenslt~. Detailed anilysis ol'thc individtitif excursion records suggests that there are two basically different types ol, cxcursions, one t\ t~c that is closely related to normal secular variation and another type that nilght he considei Cd an aborted reversal. The project will analyze and s\ nthesize PIVVIOLIS palcornagnetic rcults and make selective new discretesample ineastirements on cleven exci-ii-sions and fh(,iii, contiguous secular variation.
