9902712KodamaA shallow magnetic inclination has been reported in paleomagnetic studies of numerous tectono stratigraphic terranes distributed along Western North America. These shallow inclinations have been interpreted as requiring significant northward translation since acquisition of the magnetic signature. However, laboratory compaction studies as well or sedimentary rocks indicate that shallow inclinations in some kinds of sedimentary rocks result from compaction. This project will examine this possibility for the Valle group in Baja Mexico that previously has been used to argue for significant northward translation. Results should clarify the translation history of the peninsular Range terrane and demonstrate the role of inclination shallowing in sedimentary rocks.

9902712 Kodama在对分布于沿着北美西部的众多构造地层岩的古地磁研究中，曾报道过一种浅磁倾角。 这些浅倾角被解释为需要显著的向北平移，因为采集的磁性签名。 然而，沉积岩的实验室压实研究也表明，某些类型的沉积岩中的浅倾角是压实造成的。 这个项目将研究这种可能性的瓦莱集团在墨西哥下，以前一直被用来论证重大的北移。 结果应该澄清半岛山脉的平移历史，并证明沉积岩中倾斜变浅的作用。
