3D Structural Growth and Tectonic Geomorphology of Active Fault-Bend Folds

小行星9614675 两个重要的阻碍因素限制了我们对地壳浅层形变及其与活跃地震活动关系的理解。它们是对地震事件的时间框架缺乏了解，以及完全在地下的断层作用，也就是说，断层从未突破到地表。该项目将通过研究来研究形成于加州南部未暴露（盲）断层上方的褶皱。 1由活动褶皱产生的丘陵地貌， 2个年轻的表层沉积，3个利用威尔斯油井资料的地下构造。 可能与地震变形有关的地貌结构将通过同位素方法确定年代，然后与历史和外推的地震频率模式进行比较。 这些结果预计将有助于评估几种类型的地形之间的潜在关系，和地震活动的盲目结构。

9614675 Mueller Two important deterrents limit our understanding of shallow crustal deformation as well as its relationship to active seismicity. They are the lack of knowledge of the time frame of earthquake events, and the role of faulting that is totally subsurface, that is , faults that never break through to the surface. This project will examine folds that form above unexposed (blind) faults in southern California by studying 1 landforms on hills that are produced by active folding, 2 young surficial deposits, and 3 subsurface structure using data from oil wells. Geomorphic structures that may be related to seismic deformation will be dated by isotopic methods, and then compared to historic and extrapolated earthquake frequency patterns. Together these results are expected to be useful in evaluating the potential relationships among several types of land forms, and seismicity on blind structures.
