Refinement of the Early Cretaceous Geomagnetic Polarity ecord

来自夏威夷岩系的Larson和Hilde(1975)磁异常数据继续为晚侏罗世和早白垩世的地磁极性提供“蓝图”。陆地剖面的磁性地层学资料证实了极性模式的主要特征，并提供了与各种生物分带的对比，从而提供了地质阶段界线的对比。这项研究将在以前工作的基础上，以某些间隔为目标，在海洋记录和陆地磁性地层剖面中进行详细调查。如果在海洋异常和陆基记录中都能证实短极性克伦斯的存在，将极大地完善早白垩世的极性变化记录。

The Larson and Hilde (1975) magnetic anomaly data from the Hawaiian lineations continues to provide the "blueprint" for geomagnetic polarity during the latest Jurassic and Early Cretaceous. Magnetostratigraphic data from land sections has confirmed the main features of the polarity pattern and provided the correlation to various biozonations and hence to geologic stage boundaries. This research will build on the previous work and targets certain intervals for detailed investigation both in the oceanic record and in magnetostratigraphic sections on land. If the presence of the short polarity chrons can be substantiated both in the oceanic anomaly and land-based record, it will significantly refine the record of polarity change in the Early Cretaceous.
