Notes | Discusses 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. βThe 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.β (p.28) The major professor was E. Julius Dasch. |
