Models of Lithospheric Stresses in the Cenozoic

利特戈-贝尔泰罗尼9980551国际和平研究所建议发展岩石圈应力模型，以评估长波长岩石圈内、板块边界牵引力和地幔源应力对应力场的相对贡献。将详细讨论以下问题：1)地幔流动对板内应力场有贡献吗？2)岩石圈源区的长波贡献能否被区分？与地幔的牵引力相比，它们的相对震级是多少？3)关于新生代应力场的演化，什么可以说是一级的？关于板块重排的原因，有什么问题可以回答吗？4)板块运动的突变对板块应力状态的影响是什么？是否出现了一种新的压裂模式？这项研究将有助于我们理解板块构造和地球内部动力学之间的相互作用。

Lithgow-Bertelloni 9980551 The PI proposes to develop models of lithospheric stress to assess the relative contributions of long-wavelength intra-lithospheric, plate boundary tractions, and mantle sources to the stress field. The following questions will be addressed in detail: 1) Does mantle flow contribute to the intraplate stress field? 2) Can a long-wavelength contribution in lithospheric sources be distinguished? What is their relative magnitude compared to the mantle derived tractions? 3) What can be said to first order about how the stress field evolved during the Cenozoic? Can any questions about the cause of plate rearrangements be answered? 4) What are the consequences of abrupt changes in plate motion on the state of stress of a plate? Does a new fracturing pattern develop? This research will contribute to our understanding of the interplay between plate tectonics and the dynamics of the Earth's interior.
