9902968LeeComparison of strain accumulation and release a long relatively discrete, rapidly moving plate boundary fault zones has led to considerable insights into the dynamics of plate interactions in tectonic situation such as Japan and coastal California. However, less is known about dynamics of diffuse intraplate fault systems. Ongoing investigations are providing measures of contemporary strain accumulation across the Basin and range of central and Eastern Nevada and this project will obtain a precise chronology of late quaternary strain release in the same area. Comparison of the two date's sets should provide a test of how well this method can be applied to an intraplate system and should help understand the dynamics of Basin and Range faulting.

[9902968]通过对长时间相对离散、快速移动的板块边界断裂带的应变积累和释放的比较，可以对日本和加利福尼亚沿海等构造情况下的板块相互作用动力学有相当大的了解。然而，人们对弥漫性板内断裂系统的动力学知之甚少。正在进行的调查正在提供跨盆地和内华达州中部和东部范围的当代应变积累的措施，该项目将获得同一地区晚第四纪应变释放的精确年表。对两个数据集的比较可以检验这种方法在板内系统中的应用效果，并有助于理解盆地和山脉断裂的动力学。
