This PowerPoint presentation is part of the Whitman College petrology course. This 37-slide presentation starts by presenting a generalized map of the earth's rift system. The composition of mid-ocean ridge basalt is introduced in the context of major-element chemistry, petrography, trace elements, spreading rate, and isotope chemistry. Melt generation in terms of mantle and lithospheric structure is portrayed in a number of schematic diagrams.

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.
