Collaborative Research: The Four-Dimensional Pattern of Rifting in the Southern Gulf of California

PIS将对加利福尼亚州南部海湾进行带状水深测量，获得3.5千赫、磁力和重力剖面，并收集火山基底的疏浚样本。其目的是检验与大陆裂谷如何在构造上分段以及这是否与断裂的不对称性有关、裂谷传播如何在构造上发生以及大陆解体和最早的海底扩张伴随着何种类型的岩浆活动(S)等一般性问题的假设。加利福尼亚州海湾是边际研究的重点地区，这项研究将补充该地区正在进行和计划进行的其他研究。

The PIs will carry out a swath bathymetry survey of the southern Gulf of California, obtain 3.5 kHz, magnetic and gravity profiles and collect dredge samples of the volcanic basement. The objectives are to test hypotheses concerned with the generic problems of how continental rifts are segmented tectonically and whether this relates to asymmetries of faulting, how rift propagation occurs tectonically and what type(s) of magmatism accompanies continental break-up and earlist seafloor spreading. The Gulf of California is a MARGINS' focus site and this study will complement other research being carried out and planned for this region.
