9814698ErslevThe CD-ROM (Continental Dynamics-Rocky Mountain Transect) project is an integrated geological and geophysical investigation to evaluate lithospheric structure in a transect from Wyoming to New Mexico. 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.***

9814698 ErslevCD-ROM（大陆动力学-落基山样带）项目是一个综合地质和地球物理调查，以评估从怀俄明州到新墨西哥州样带的岩石圈结构。 该项目已获得1998-2001年期间的资金。 该项目涉及来自12所大学的17名调查人员。光盘项目的主要目标之一是了解Laramide结构如何受到较老大陆组合结构的影响，以及Laramide上地壳缩短如何适应下地壳和上地幔。 该项目的首席研究员是公认的Laramide构造专家。 他的研究将通过对Laramide结构几何形状和沿沿着CD-ROM断面的事件序列进行详细分析来加强CD-ROM项目。 这对项目的成功很重要，因为必须确定Laramide构造作用的影响，以区分它们与较老（前寒武纪）和较年轻（格兰德河裂谷）事件的签名，这些事件也对北美克拉通西部的岩石圈结构做出了贡献。 此外，他还可以为项目提供宝贵的建议，即在断面中准确定位地震测线，以便最大限度地获取有关Laramide基底的克拉通内构造作用的信息。
