中文摘要
岩石圈-地幔系统的热-力学稳定性最终取决于构造力的非线性相互作用以及由非线性温度和应变率相关流变学引起的响应。 在这个为期两年的项目中,计划研究大洋和大陆岩石圈的蠕变不稳定性,岩石圈具有弹粘塑性或粘弹性流变学,具有现实的蠕变参数。 他还将研究保持板完整性的关键因素。 所有这些问题都是丰富的非线性和承诺令人惊讶的,但基本的结果,这将有助于阐明岩石圈和地幔动力学的关键特征的参数范围内有关的地质系统。
英文摘要
9814791Yuen The thermal-mechanical stability of the lithosphere-mantle system ultimately depends on the nonlinear interaction of the tectonic forces and the responses elicited from the nonlinear temperature-and strain-rate dependent rheology. In this two-year project the P. I. plans to study creep instabilities in both the oceanic and continental lithospheres, which have either an elasto-visco plastic or a viscoelastic rheology with realistic creep parameters. He will also study critical factors that maintain the integrity of slabs. All of these problems are rich in non-linearity and promise surprising but fundamental results, which should help to elucidate the critical character of lithospheric and mantle dynamics in the parameter range relevant to geological systems.
