Construction of a timely, powerful, and public GIS database to resolve the landscape evolution of the interior western U.S.Joel Pederson, EAR-0341067Utah State UniversityAbstract The Colorado Plateau and adjacent Rocky Mountains form one of the great orogenic plateaus of the world. The study of the balance and interaction between erosion, rock uplift, and surface elevation in this region has been a fundamental issue in the geosciences for over a century, and the region is currently undergoing a rejuvenation of multidisciplinary research into these longstanding problems. Different conceptual models for the landscape evolution of the region predict different amounts and timing of uplift and erosion, and existing hypotheses are actually not testable because essential data about erosion, rock uplift, and surface uplift are not available. This proposed research will complete successful initial work on a novel scientific approach to provide the key data needed to solve these classic problems. As important, it will result in an expandable, publicly available, GIS-database framework that will be a much-needed catalyst for research advances. The goals of this project include mapping post-Laramide rock uplift and erosional exhumation from stratigraphic and geomorphic evidence preserved in the landscape, and then compiling these data into a GIS. The Colorado Plateau and middle Rocky Mountain region is ideal for such an effort because its stratigraphy is well documented, key markers of exhumation are present, and because of the large amount of interest and ongoing research into these problems. Based on feedback from, and the actual use of, the published initial data by other researchers, the completion of this project will be of great utility to the geomorphic, tectonic, and geophysical modeling communities for testing scenarios of landscape evolution of the western interior U.S. This work should therefore be a timely catalyst for innovative advances in the understanding the Cenozoic landscape of the western U.S.

建立一个及时、强大、公开的地理信息系统数据库，以解决美国西部内陆地区的景观演变问题。乔尔·佩德森，犹他州立大学，2007 - 0341067摘要科罗拉多高原和邻近的落基山脉是世界上最大的造山高原之一。 该地区的侵蚀，岩石隆起，地表高程之间的平衡和相互作用的研究一直是地球科学的一个基本问题超过世纪，该地区目前正在经历一个多学科的研究，这些长期存在的问题的复兴。 该地区景观演变的不同概念模型预测了不同的隆起和侵蚀量和时间，现有的假设实际上是不可检验的，因为没有关于侵蚀，岩石隆起和地表隆起的基本数据。这项拟议的研究将成功完成一项新的科学方法的初步工作，以提供解决这些经典问题所需的关键数据。 同样重要的是，它将产生一个可扩展的、公开可用的GIS数据库框架，这将成为研究进展急需的催化剂。 该项目的目标包括从保存在景观中的地层和地貌证据中绘制Laramide后岩石隆起和侵蚀剥露图，然后将这些数据汇编成地理信息系统。 科罗拉多高原和落基山脉中部地区是进行这种努力的理想地区，因为它的地层学有很好的文献记载，有重要的剥露标志，而且对这些问题有大量的兴趣和正在进行的研究。 根据其他研究人员的反馈和实际使用，已公布的初始数据，该项目的完成将对地貌，构造和地球物理建模社区具有很大的实用性，用于测试美国西部内陆景观演化的场景。因此，这项工作应该是理解美国西部新生代景观的创新进展的及时催化剂。
