A Structural And Paleomagnetic Analysis Of The Basalts Of Summit Creek, Anne Fetrow

Summer Research

This study is a detailed analysis of the structural geology and paleomagnetism of the Basalts of Summit Creek. Located southeast of Mount Rainier, this section of layered basaltic flows formed during the Eocene Epoch (55 to 45 Ma). The exact origin of the Basalts of Summit Creek is unknown, but there appears to be a growing connection between the Basalts of Summit Creek and the Crescent Basalts, which are Eocene flood basalts located on the Olympic Peninsula (Clark, 1989). This study attempts to provide a greater understanding of the emplacement and deformation of the Basalts of Summit Creek and any …
