These lecture notes discuss equilibrium crystallization in two component systems. Isotherms and boundary curves are introduced in this section. Other topics discussed include congruently melting intermediate compounds, incongruently melting compounds, and binary solid solution in ternary systems. Annotated phase diagrams are included throughout the text. This resource is part of the Teaching Petrology ... Full description.

This set of lecture notes covers a number of topics including magmatic differentiation, chemical variation in rock suites, partial melting, fractional melting, crystal fractionation, Bowen's reaction series, and magma mixing. Graphs discussed include oxides vs. SiO2, and MgO vs. SiO2. The notes are arranged in outline form and contain many informative diagrams. This resource is part of the Teaching ... Full description.

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 ... Full description.

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 ... Full description.

These lecture notes discuss metamorphic textures and the mechanisms that create them. A discussion of foliation covers types of stress and the development of foliated rocks from slate to gneiss. Five modes of metamorphic differentiation are introduced including preservation of original compositional layering, transposition of original bedding, solution and re-precipitation, preferential nucleation, ...

This web site includes almost 200 photomicrographs of rocks and minerals. The thin sections are all in transmitted white light, some in plane polarized light, but most with crossed polarizers on. The majority of the pictures show a field of view 1.5 mm long (about 80X magnification). Other magnifications are indicated where different. The thin sections are categorized into minerals, igneous, metamorphic, ... Full description.
