Reassessment of Geological Tie Points Across the Gulf of California

9614674库存 下加利福尼亚在过去15 Ma内从墨西哥大陆断裂，但位移量（据认为约为300 km）尚不清楚。 需要更好地测量位移，这有几个目的，包括将加州湾内的滑动与太平洋和北美板块之间的净运动联系起来，以及了解海湾裂谷和圣安德烈亚斯断层运动之间的运动学。 由于墨西哥湾没有开发磁条，目前的估计是基于横跨墨西哥湾的一个单一连接点，本项目旨在重新评估这一关键的岩性相关性，并应用现代方法建立额外的联系。 预计结果将提供一个更强大和准确的措施，巴哈位移整个加州湾相对于墨西哥大陆。

9614674 Stock Baja California has been rifted from mainland Mexico within the last 15 Ma, however the amount of displacement, thought to be approximately 300km, is not well known. A better measure of displacement is need for several purposes including relating slip within the Gulf of California to net motion between the Pacific and North American plates and understanding the kinematics between Gulf rifting and the San Andreas fault motions. Because magnetic stripes are not developed in the Gulf, the present estimate is based on a single tie point across the Gulf, and this project is aimed at re-evaluating this critical lithologic correlation and to apply modern methods to establish additional ties. Results are expected to provide a more robust and accurate measure of Baja displacement across the Gulf of California relative to mainland Mexico.
