These lecture notes introduce magmatism and petrology as they relate to the oceanic lithosphere. The notes cover ophiolite sequences and types of volcanic settings found in ocean basins. A section about basalt includes discussion of location, composition and origin of mid-ocean ridge basalts. Ocean island basalts are further discussed with regards to occurrence, composition and origin. These notes include graphs, maps and phase diagrams. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html
Part of the Cutting Edge collection. The NAGT/DLESE On the Cutting Edge project helps geoscience faculty stay up-to-date with both geoscience research and teaching methods.
