Rating

These lecture notes are part of a series of lectures available on the geology department website at Tulane University. Topics covered include criteria for the classification of igneous rocks, field identification of minerals present in hand sample, thin section examination and chemical analysis. The general chemical classification covers silica content (silica saturation), aluminum saturation, and alkaline and subalkaline rocks.

Rating

This set of lecture notes discusses the occurrence and tectonic settings of igneous rocks near convergent plate margins. A discussion of petrography includes major element composition, calc-alkaline trends in ternary diagrams, trace element variations, isotopes to distinguish magma sources, and the origin of igneous rocks at convergent margins. The lecture notes include helpful illustrations, maps and phase diagrams. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html

Thermodynamics and Metamorphism
Conditions of Use:
Remix and Share
Rating

These lecture notes provide an introductory lesson in thermodynamics to help students better understand the relationships depicted on phase diagrams. The first and third laws of thermodynamics and Gibb's Free Energy are discussed. Solid-solid reactions are covered in the context of the Sillimanite-Kyanite-Andalusite P-T graph. Devolatization reactions, reaction boundaries, and reaction rates are also covered in the notes. The notes contain many graphs relating pressure, temperature, and Gibb's Free energy.

Triangular Plots in Metamorphic Petrology
Conditions of Use:
Remix and Share
Rating

These lecture notes discuss the use of three component systems in metamorphic petrology. Common triangular plots used in metamorphic rocks are presented with annotated ternary diagrams. The presentation includes four criteria for reducing the number of components in a system to a workable number. There is also discussion of the issue of lost information when reducing the number of components in a system.
