9706255 Louie There is a large debate over the possibility of generating regionally extensive, large-magnitude extensional faults at moderate to shallow depths. Indeed, most shallow faults can be shown from a variety of methods to be steeply dipping. This study has identified the Dixie Valley fault system as having a high potential to be active and shallow, and the data to be collected should be able to discriminate between competing hypotheses. If the fault can be shown to be active and of low dip, it will have a significant impact on the models of both active and ancient deformation in extensional regimes.

[9706255] Louie对于在中浅深度产生区域性广泛的、大震级的伸展断层的可能性存在很大的争论。事实上，从各种方法可以看出，大多数浅层断层都是陡倾的。这项研究已经确定了迪克西谷断层系统具有活跃和浅的高潜力，并且收集的数据应该能够区分相互竞争的假设。如果该断裂能被证明是活动的和低倾角的，它将对伸展区活动和古变形模式产生重大影响。
