RUI: COLLABORATIVE RESEARCH: Tectonic and Stratigraphic Evolution of the Loreto Basin, Baja California Sur: A Transform-Rift Basin

该合作项目将研究上新世-第四纪Loreto盆地的构造和地层演化，该盆地位于下加利福尼亚州南部加利福尼亚湾的边缘。一个始于5Ma的转换裂谷系统形成了Loreto及其相关盆地，但尽管有良好的暴露和可达性，但迄今为止尚未对其进行详细研究。磁地层学将与四个凝灰岩的放射性定年和其他工作人员的古生物资料相结合，对盆地的演化进行良好的年代地层学控制。这些数据将有助于研究生长结构在盆地地层几何上的作用。这些结果将解决加利福尼亚湾构造学中的主要突出问题，并对一般的斜裂边缘构造学具有重要意义。

This collaborative project will study the structural and stratigraphic evolution of the Pliocene-Quaternary Loreto Basin, which lies along the margin of the Gulf of California in Baja California Sur. A transform-rift system beginning at 5Ma formed the Loreto and related basins but they have not been studied in detail until now, despite good exposure and accessibility. Magnetostratigraphy will be combined with radiometric dating of four tuffs and paleontological data of other workers to give good chronostratigraphic control of the basin's evolution. These data will permit investigation of the role of growth structures on the stratigraphic geometries in the basin. The results will resolve major outstanding problems in the tectonics of the Gulf of California, and will have important implications for the tectonics of obliquely-rifted margins in general.
