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

项目研究员将对加州湾南部进行一次条带测深调查，获得3.5千赫、磁力和重力剖面图，并收集火山基底的疏浚样品。 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层的不对称性有关的一般性问题有关的假设，裂谷如何在构造上扩展，以及伴随大陆分裂和最早的海底扩张的岩浆活动类型。 加州湾是MARGINS的重点研究地区，本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.
