Support for Analog Modeling of Tectonic Processes Workshop

该项目为参加2017年5月初在德克萨斯州奥斯汀举行的“构造过程模拟建模”研讨会的美国研究人员和学生提供旅费支持。本次研讨会以2015年成功举办的这一主题研讨会为基础。模拟模型实验极大地促进了对构造过程的理解。在这些实验中，较弱的材料（砂、粘土等）代替岩石，在受控条件下以高应变率变形，从而产生地球构造（断层、褶皱）和大尺度构造特征（山带、裂谷系统）发育的比例模型。本次研讨会的目的是将构造模拟建模社区聚集在一起，讨论该领域的未来方向，与基于计算机的建模者建立合作关系，并开发课程材料。研讨会的参与者包括实验人员、计算机建模者、学生和在课堂上使用模拟模型的教师。研讨会将促进早期职业研究人员的模拟建模技能，从而发展未来的构造学劳动力。讲习班将促进学生、早期职业科学家和来自代表性不足的地球科学群体的研究人员的参与。在过去的10年里，由于模拟材料的系统流变测试和使用激光和图像处理技术进行数据分析，导致模拟建模的定量方面得到加强，从而推动了地壳变形模拟建模的革命。这场革命的先锋一直在欧洲，那里的实验室一直在实施新的方法，这些方法可以更好地控制实验条件，更准确地缩放变形，并改进对变形和变形过程演变的见解。这个为期多天的研讨会聚集了美国和国际领先的地球科学家，他们使用模拟和数值建模来讨论革命性的实验建模技术，以及执行和分析规模实验的挑战。本次研讨会为研究人员提供了一个独特的、非正式的机会来分享他们的一些最佳实践。作为一种促进意见交流的机制，将进行半天的物理实验，然后进行半天的数值分析，以鼓励整个小组参与实验设置、故障排除、数据收集和分析，并使每个社区对彼此的需求更加敏感。为研讨会开发的课程材料将通过科学教育资源中心免费提供。

ThisThis project provides funding for travel support for U.S. researchers and students to attend a workshop on "Analog Modeling of Tectonic Processes" to be held in Austin, Texas, in early May of 2017. The workshop builds on a successful workshop on this topic held in 2015. Analog model experiments contribute substantially to the understanding of tectonic processes. In these experiments, weaker materials (sand, clay, etc.) take the place rocks and are deformed at high strain rates under controlled conditions thus producing scale models of the development of earth structures (faults, folds) and large-scale tectonic features (mountain belts, rift systems). The aim of this workshop is to bring together the tectonics analog modeling community to discuss future directions in the field, build collaborations with computer-based modelers, and develop curriculum materials. The workshop participants include experimentalists, computer modelers, students, and instructors who use analog models in their classrooms. The workshop will promote the analog modeling skills of early career researchers, thereby developing the future workforce in tectonics. The workshop will promote the participation of students, early career scientists, and researchers from underrepresented groups in the earth sciences.The past 10 years have seen a revolution within analog modeling of crustal deformation spurred by systematic rheological testing of analog materials and use of laser and image processing techniques for data analysis leading to a strengthening of the quantitative aspect of analog modeling. The vanguard of this revolution has been in Europe where laboratories have been implementing new approaches that permit greater control on experimental conditions, more accurate scaling of deformation and improved insights into the evolution of deformation and deformation processes. This multi-day workshop gathers leading US and international geoscientists who use analog and numerical modeling to discuss techniques that are revolutionizing experimental modeling, as well as challenges for performing and analyzing scaled experiments. This workshop provides a unique and largely informal opportunity for researchers to share some of their best practices. As a mechanism to foster idea-sharing, a half-day physical experiment followed by a half-day numerical analysis will be performed to encourage the entire group to engage in experimental set-up, trouble shooting, data gathering and analysis and to sensitize each community to the needs of the other. Curriculum material developed for the workshop will be freely available through the Science Education Resource Center.
