The southern part of the Death Valley area contains the intersecting Garlock and southern Death Valley fault zones and the tectonic boundary between the Basin and Range province and the northeastern Mojave Desert. The northeastern Mojave province, previously thought to not be extended, has recently been found to contain a west-rooting detachment fault system involving late Miocene strata in the Halloran Hills. This project is designed to provide the detailed maps, structural geometry and kinematic information of the detachment required to reassess the tectonics of the Mojave block and how the new information affects the late Cenozoic tectonic history of the region.

死亡谷地区的南部包括相交的加洛克断裂带和南部死亡谷断裂带，以及盆山省和莫哈韦沙漠东北部的构造边界。之前被认为不会延伸的东北部莫哈维省，最近被发现包含一个由西向根的拆离断层系统，涉及哈洛兰山脉的晚中新世地层。该项目旨在提供重新评估莫哈韦地块构造所需的详细地图、构造几何学和滑脱运动学信息，以及新信息如何影响该地区晚新生代的构造史。
