Strike-Parallel Variations in Clay Mineraology and Their Impact on the Cascadia Seismogenic Zone

研究的目的是了解俯冲带滑脱力学的基本和关键输入参数，以及蒙脱石输入的定量效应。 PI 将对 DSDP/ODP 钻井样品进行研究，以确定其粘土矿物学及其如何影响地震行为和滑移稳定性。重点将放在卡斯卡迪亚边缘的样本上，但结果也将与其他地震带进行比较和相关。

The objective of the study is to understand the basic and critical input parameter for the mechanics of subduction zone decollements, the quantitative effect of smectite input. The PI will carry out a study of the DSDP/ODP drilling samples to determine their clay mineralogy and how it influences seismic behavior and slip stability. The focus will be on samples from the Cascadia margin, but the results will be compared to and relevant to other seismogenic zones as well.
