NotesDiscusses the Roseburg Formation basalts, their relationship to other basalt flows in Oregon, their chemical composition and likely geologic origin (oceanic ridge / hotspot). Charts, tables, geologic maps. β€œThe basalt flows in the Roseburg region are mostly thick and massive with pillowed margins. Lateral gradation into pillows and pillow breccias is common. Pillows are usually 0.5 to 1.0 m in diameter and, in some areas along the North Umpqua River, they make up entire flows up to 10 m thick.” (p.28) The major professor was E. Julius Dasch.
