9903259SmithA 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.

9903259Smith 在对北美西部分布的众多构造地层的古地磁研究中报告了浅磁倾角。 这些浅倾角被解释为自获取磁特征以来需要显着的向北平移。 然而，实验室压实研究以及沉积岩研究表明，某些沉积岩的浅倾斜是由压实造成的。 该项目将研究墨西哥下巴哈瓦莱集团的这种可能性，该集团以前曾被用来主张重要的向北平移。 结果应阐明半岛山脉地体的平移历史，并证明沉积岩倾斜变浅的作用。
