Workshop Support: GeoFrame Walker Lane

工作坊支持：GeoFrame Walker lane首席研究员：Daniel Stockli，堪萨斯大学劳伦斯分校GeoFrame是一项综合地质倡议，通过时间和空间从多维角度观察北美大陆的建设和改造。该计划的目标可以通过系统地整合地质和地球测时调查以及作为EarthScopeProgram一部分的前所未有的地球物理成像结果来实现。全面的地球范围地球物理实验有可能成为地球科学的变革性项目，为对北美大陆演化的更完整的地球动力学理解奠定基础。GeoFrame概述了美国周边的七个重点地区，专门解决北美大陆长期增长和变化（例如，裂谷）的基本问题。GeoFrame的工作设想，这些重点现场调查需要被动震源接收器的地图规模阵列和相关的主动震源地震研究，以及与地质合成和针对性研究相结合的互补地球物理。对这些地区的研究应加紧进行，以配合计划中的USArray步骤。这些重点地点之一是加利福尼亚州东部和内华达州西部的沃克巷地区。我们建议组织一个为期两天的研讨会，将在沃克巷工作的地质学家和地球物理学家聚集在一起。考虑到USArray“大脚”阵列的部署时间表，这个GeoFrame焦点站点研讨会特别及时。本次研讨会旨在促进综合地球物理和地质方法的组织，以了解沃克巷的地球动力学演化。EarthScope的设计和实施隐含着这样一种认识，即在这些问题上取得进展需要在互补学科中工作的研究人员的合作努力。本次研讨会旨在建立一个广泛的研究人员社区，专注于沃克巷的综合地球物理和地质调查。因此，它将为工作组之间的合作开辟新的途径，并确定新的研究需求和机会。我们期望通过继续从加利福尼亚湾向北进入内华达州的陆上工作，将结果和努力与美国国家科学基金会在加利福尼亚湾的大陆岩石圈边缘破裂（RCL）计划相结合。

Workshop Support: GeoFrame Walker LanePrincipal Investigator:Daniel Stockli, University of Kansas, LawrenceGeoFrame is an integrative geologic initiative that takes a multi-dimensional view of thebuilding and modification of the North American continent through time and space. Theinitiative's goals can be achieved by systematic integration of geologic and geochronometricinvestigations and the results from unprecedented geophysical imaging as part of the EarthScopeProgram. The overarching EarthScope geophysical experiment has the potential to be atransformative program for the Earth Sciences, building a foundation for a more completegeodynamic understanding of the evolution of the North American continent. GeoFrame hasoutlined seven focus regions across the conterminous U.S., specifically to address fundamentalaspects of the growth and modification (e.g., rifting) of the North American continent throughtime. The GeoFrame effort envisions these focus site investigations to entail map-scale arrays ofpassive source seismic receivers and associated active source seismic studies and complementarygeophysics in conjunction with geologic-based synthesis and targeted studies. Study of theseregions should proceed in an intensified fashion, in concert with planned USArray steps.One of these focus sites is the Walker Lane region in eastern California and westernNevada. We propose to organize a two-day workshop that will bring together a wide spectrum ofgeologists and geophysicists who are working in the Walker Lane. This GeoFrame focus siteworkshop is particularly timely given the deployment schedule of the USArray "BigFoot" array.This workshop is intended to facilitate the organization of an integrated geophysical andgeological approach to understanding the geodynamic evolution of the Walker Lane.Implicit in the design and implementation of EarthScope is the recognition that progress onissues such as these requires the collaborative efforts of researchers working in complementarydisciplines. This workshop is designed to build a broad-based community of researchers focusedon integrative geophysical and geological investigation of the Walker Lane. As such, it will opennew avenues of collaboration between working groups and identify new research needs andopportunities. We anticipate the integration of results and efforts with the NSF MarginsRupturing of Continental Lithosphere (RCL) initiative in the Gulf of California by continuing thework onshore from the Gulf of California to the north into Nevada.
