This 93-slide PowerPoint presentation is part of the Whitman College petrology course. The presentation discusses the compatibility of elements, addressing Goldschmidt's Rules, fractionation, and bulk distribution coefficients. Other topics described include batch melting, fractional crystallization, Rayleigh fractionation, rare-earth elements, large-ion-lithophile and high field strength elements. ... Full description.

This PowerPoint presentation is part of the Whitman College petrology course. The presentation covers the origin of basaltic magmas. Two types of basalt in ocean basins are compared (tholeiitic and alkaline). Composition of mantle-derived magmas and sources of mantle material are listed. Discussion of how the mantle melts, touching on the contribution of volatiles, pressure and composition, is included. ... Full description.

This PowerPoint presentation is part of the Whitman College petrology course. Subjects include fractional crystallization, compaction, flow segregation, volatile transport, the Soret Effect, thermogravitational diffusion, magma mixing, and assimilation. Tectonic-igneous relationships are also addressed. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html ... Full description.

This PowerPoint presentation is part of the Whitman College petrology course. This 50-slide presentation introduces layered mafic intrusions around the world. The chapter discusses various layered mafic complexes in cross section and plan view, and also describes stratigraphy within the complexes. The presentation further describes processes within the complexes, such as crystallization, differentiation, ... Full description.

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 ... Full description.

This PowerPoint presentation is part of the Whitman College petrology course. This 29-slide presentation covers the compositional evolution of basalt using high field strength, large-ion lithophile, rare earth elements, and isotope geochemistry. Mantle reservoirs (depleted mantle, bulk silicate earth, enriched mantle, prevalent mantle, High mu mantle) are discussed and illustrated. This resource is ... Full description.

This PowerPoint presentation is part of the Whitman College petrology course. This 17-slide presentation addresses the major flood basalts. The Columbia River flood basalts are discussed in detail. Other flood basalts that are covered include the Keeweenawan, Deccan, Parana and Karroo.

This 50 slide PowerPoint presentation introduces the basic structural facets of an island arc system. Magma series (tholeiitic, alkaline, calc-alkaline) and differentiation within magma series are related to the major elements. Other trends in magma series (spatial, temporal, trace element, isotope) are presented. Petrogenesis of magmas is illustrated in terms of mantle flow, rate of subduction and ... Full description.
