The PI will continue his work on the estimation of in situ stress magnitudes from records of wellbore failure in ODP boreholes. The oceanic basins have a notable lack of stress measurements. The approach will be to use the borehole televiewer and formation microscanner logs and measure rock strength in the laboratory. Numerical modelling of the lithospheric stress based on thermal relaxation data will also be conducted. This work will provide useful data about the stress regime of oceanic crust.

PI将继续进行原位估算工作 ODP井眼破裂记录应力值 钻孔 海洋盆地明显缺乏压力 测量. 方法是使用钻孔电视 和地层微扫描仪测井，并测量岩石强度， 实验室 岩石圈应力的数值模拟 热松弛数据也将进行。 这项工作将 提供了有关大洋地壳应力状况的有用数据。
