The Nature of Laramide Intracratonic Deformation: Detailed Structural Studies to Supplement the 1999 CD-Rom Seismic Experiments

CD-ROM(大陆动力学-落基山脉样带)项目是一项综合的地质和地球物理调查，目的是评估怀俄明州到新墨西哥州的样带的岩石圈结构。该项目得到1998-2001年期间的资助。该项目涉及来自12所大学的17名研究人员。光盘项目的主要目标之一是了解拉拉米德结构可能如何受到较老的大陆组装结构的影响，以及拉拉米德上地壳缩短是如何适应下地壳和上地幔的。该项目的首席研究员是一位公认的拉莱姆构造专家。他的研究将通过对沿光盘横断面的拉拉酰胺结构几何和事件顺序进行详细分析来加强光盘项目。这对该项目的成功很重要，因为必须确定拉莱姆构造作用的影响，以区分它们与更老(前寒武纪)和更年轻(里奥格兰德裂谷)事件的特征，这些事件也对北美克拉通西部目前的岩石圈结构做出了贡献。此外，他还可以为该项目提供有价值的建议，即在横断面上准确地定位地震线的位置，以便最大限度地了解与拉莱姆基底有关的克拉通内构造作用。*

The project has been funded for the time period 1998-2001. The project involves 17 investigators from 12 universities. One of the major goals of the CD-ROM project is to understand how Laramide structures may have been influenced by older continental assembly structures and how Laramide upper crustal shortening is accommodated in the lower crust and upper mantle. The Principal Investigator of this project is a recognized expert in Laramide tectonics. His studies will strengthen the CD-ROM project by carrying out detailed analyses of Laramide structural geometries and sequences of events along the CD-ROM transects. This is important to the success of the project because the effects of Laramide tectonism must be identified to discriminate their signatures from those of older (Precambrian) and younger (Rio Grande rift) events that have also contributed to the present lithospheric structure of the western part of the North American craton. In addition, he can provide valuable advice to the project about exactly where to site the seismic lines in the transects so as to maximize information about Laramide basement-involved intracratonic tectonism.***
