与岩石圈拉伸相比,岩石圈弯曲可能为断层的形成和发展过程提供了一个根本不同的窗口。调查人员将利用这一窗口,对所有可用数据的海沟的水深数据和侧扫声纳图像进行系统分析。沟槽提供了一种独特的方法,将断层特征与形成断层系统所需的应变量联系起来。二维数值模型将用于将岩石圈性质与观测到的断层间距及其偏移幅度联系起来。
英文摘要
Lithospheric bending may give a fundamentally different window into the processes of fault initiation and development than does lithospheric stretching . The investigators will take advantage of this window by a systematic analysis of bathymetric data and sidescan sonar images for all trenches where data is available. Trenches offer a unique way to relate falut characteristics to the amount of strain required to develop a system of faults. Two-dimensional numerical models will be used to relate lithospheric properties to the observed spacing of faults and the amplitude of their offset.
