Jurassic Extensional Arc - Continental Rift Transition, Mojave - Sonoran Deserts

最近的研究表明，三叠纪至中期 美国西南部的侏罗纪弧形山脉 从克拉马斯到索诺兰沙漠的伸展地堑 初步工作表明，弧也可能是网站 莫哈韦沙漠到索诺兰的大规模左旋裂谷 沙漠部分，北方继续平移 部分。 该项目将进行详细的沉积学和 地质年代学研究旨在验证这些工作假设。 结果可以证明两者的重要性和时机 沿着中生代岛弧的张扭和压扭作用 美国西南部。

Recent studies have suggested that the Triassic to middle Jurassic arc of the southwest Cordilleran United States occupied an extensional graben from the Klamaths to the Sonoran Desert. Preliminary work indicates that the arc may also have been the site for large-scale sinestral rifting in the Mojave Desert to Sonoran Desert portion, with continued transpression in the northern portion. This project will conduct detailed sedimentologic and geochronlogical studies aimed at testing these working hypothesis. Results may demonstrated the importance and timing of both transtension and transpression along the Menozoic arc of the southwestern United States.
