The objective of this proposal is to continue current processing and interpretation of 5 Gbytes of land-sea wide-angle reflection/refraction seismic data recorded in an expanding spread configuration of the 1986 GLIMPCE project in Lake Superior. The specific geophysical objectives are: (1) to extract, identify, and analyze events returned from Moho and sub-Moho depths, to test the correlation between the reflection and refraction Moho for both P & S phases, (2) to examine the nature of seismically transparent and layered crust at the crust-mantle boundary, and (3) to determine the seismic velocity structure within the Keweenawan rift. The more geological objectives are to determine: (1) the evolution of the Keweenawan rift, (2) if true oceanic crust exists along the rift's axis, (3) if there is a true continent/ocean boundary, and (4) a comparison of these results with modern rifts.

该提案的目标是继续处理和解释1986年在苏必利尔湖的GLIMPCE项目扩展分布配置中记录的5gb陆海广角反射/折射地震数据。具体的地球物理目标是：(1)提取、识别和分析莫霍和亚莫霍深度返回的事件，测试P和S相反射和折射莫霍的相关性；(2)研究壳幔边界地震透明层状地壳的性质；(3)确定Keweenawan裂谷内的地震速度结构。更多的地质目标是确定：(1)Keweenawan裂谷的演化，(2)裂谷轴线上是否存在真正的海洋地壳，(3)是否存在真正的大陆/海洋边界，以及(4)将这些结果与现代裂谷进行比较。
