COLLABORATIVE RESEARCH: Paleomagnetic Investigation of Late Cretaceous and Early Tertiary Volcanic Rocks

晚白垩世至古新世期间北美的明显极地漂移路径包含一个偏转或尖点，可能反映了一个主要的板块重组时期。然而，APW的分辨率不足以证明尖端两侧的部分是小圆路径，并且尖端是明显的断裂。该项目将利用蒙大拿州晚白垩世至始新世的几个火山岩序列，利用标准的古地磁技术来精炼北美晚白垩世的视极游走轨迹。这项工作将与密歇根理工大学的研究人员合作进行。

The apparent polar wander path for North America during the Late Cretaceous to Paleocene interval contains a deflection or cusp that may reflect a period of major plate reorganization. However, the resolution of the APW is insufficient to demonstrate that portions on either side of the cusp are small circle paths and that the cusp is a distinct break. This project will utilize several volcanic sequences of Late Cretaceous to Eocene age in Montana to refine, using standard paleomagnetic techniques, the North American Late Cretaceous apparent polar wander path. The work will be conducted in collaboration with researchers at the Michigan Technological University.
