We are proposing to hold a workshop on Numerical Modeling of Mantle and Lithospheric Dynamics to build on the success of the 2005 Boulder workshop on Mantle Convection. This workshop will be broader in terms of audience than the Boulder workshop in that we will bring together both the mantle convection and lithospheric dynamics communities. We wish to discuss scientific advances and, importantly, technical and scientific issues related to the quantitative modeling of the origin and evolution of the mantle-lithosphere system. Recent developments in cluster computing, tera-scale resources, and software support and code-sharing efforts of the CIG have brought about major opportunities for scientific progress, such as the prospect of truly combining lithospheric-scale deformation models with mantle convection computations. However, several current science issues remain unresolved and understanding the dynamics of these in a predictive, quantitative sense, is intimately connected to computational issues, for example: How can we efficiently model thermo-chemical convection numerically, in spherical geometries, with adequate treatment of entrainment? How can we incorporate faulted and moving plate boundaries in spherical geometry, and study regionally realistic subduction system evolution? How can we accurately incorporate strain localization and large viscosity variations, and what are the appropriate macroscopic descriptions for sub-scale processes? The workshop will be held over three days on July 9-11, 2008 at U.C. Davis. The workshop conveners have worked together to propose a diverse and stimulating group of speakers and topics. The conference format includes a range of keynote and workshop style presentations, with ample room for poster viewing and structured, as well as unstructured, discussion. This workshop will have several broader impacts beyond advancing numerical modeling methods in the mantle and lithospheric dynamics communities. First, it will serve to train graduate students and researchers in fundamental methods used in numerical modeling. One special session each afternoon is reserved for the specific purpose of teaching the fundamentals of some of the most important numerical methods already in use or anticipated to hold great potential for the mantle convection and lithospheric dynamics communities. Second, the workshop will serve to strengthen the new and growing community of lithospheric-dynamics modelers in the US. Finally, the workshop will facilitate starting collaborations between mantle dynamics and lithospheric dynamics modelers.

我们提议举办一次地幔和岩石圈动力学数值模拟研讨会，以 2005 年博尔德地幔对流研讨会取得的成功为基础。这次研讨会的受众范围将比博尔德研讨会更广泛，因为我们将汇集地幔对流和岩石圈动力学界。我们希望讨论科学进展，更重要的是，讨论与地幔-岩石圈系统起源和演化定量建模相关的技术和科学问题。 CIG在集群计算、万亿级资源以及软件支持和代码共享方面的最新发展为科学进步带来了重大机遇，例如将岩石圈尺度变形模型与地幔对流计算真正结合起来的前景。然而，当前的几个科学问题仍未得到解决，从预测性、定量意义上理解这些问题的动力学与计算问题密切相关，例如：我们如何才能有效地在球形几何中对热化学对流进行数值模拟，并充分处理夹带？我们如何将断层和移动板块边界纳入球形几何中，并研究区域真实的俯冲系统演化？我们如何准确地结合应变局部化和大的粘度变化，以及对于小尺度过程的适当的宏观描述是什么？该研讨会将于 2008 年 7 月 9 日至 11 日在加州大学伯克利分校举行，为期三天。戴维斯.研讨会召集者共同努力提出了多元化且令人兴奋的演讲者和主题。会议形式包括一系列主题演讲和研讨会风格的演示，并为海报观看和结构化以及非结构化讨论提供了充足的空间。除了推进地幔和岩石圈动力学界的数值模拟方法之外，本次研讨会还将产生更广泛的影响。首先，它将用于培训研究生和研究人员使用数值建模的基本方法。每天下午预留一场特别会议，专门用于教授一些已在使用或预计对地幔对流和岩石圈动力学界具有巨大潜力的最重要数值方法的基础知识。其次，该研讨会将有助于加强美国新的、不断增长的岩石圈动力学建模者社区。最后，研讨会将促进地幔动力学和岩石圈动力学建模者之间的合作。
