伯班克0001044一个长期存在的构造问题集中在地壳块体之间的斜向运动所产生的应力的调节模式上。 该项目将利用北方欧文斯谷、怀特-因约山和鱼湖谷、东加州剪切带的一部分，检验关于大陆张拉性质和从伸展向张拉过渡的几个假设。 该研究将为大陆张扭作用的性质提供详细的U-Th/He、裂变径迹和ArAr年代学依据。 这些结果对于重建南加州从中新世到最近的应力场历史是很重要的，并且应该有助于理解其他地方的扭张行为。
英文摘要
Burbank0001044A long-standing structural problem focuses on the modes of accommodation of the stresses that arise due to oblique motion between crustal blocks. The project will test several hypotheses regarding the nature of continental transtension and a transition from extension to transtension, using the northern Owens Valley, White-Inyo Mountain and Fish Lake Valley, parts of the Eastern California Shear Zone. This study promises to bring detailed U-Th/He, fission-track and ArAr chronologic perspective to bear on the nature of continental transtension. Results are important for reconstruction of the stress field history of southern California from Miocene times to recent, and should be helpful in understanding transtensional behavior elsewhere.
