This site is a lecture about crystal structure from Dr. Stephen Nelson at Tulane University. Topics include axial ratios, intercepts of crystal faces (Weiss Parameters), determination of the Miller Index of a crystal, the modified notation of hexagonal systems, which is referred to as Miller-Bravais Indices, and using the Miller Index notation to designate crystal forms. Tables and illustrations accompany the text.

This PowerPoint presentation is part of the Whitman College petrology course. The presentation covers isobaric ternary T-X diagrams (An-Di-Fo), liquidus, intensive variables, cotectic, peritectic, and cooling paths. Solid solution and 4 component diagrams are described as well as the effect of water on melting temperatures.

This PowerPoint presentation is part of the Whitman College petrology course. The presentation covers classification of phaneritic igneous rocks, gabbroic rocks, ultramafic rocks, pyroclastic rocks and volcanic rocks using triangular diagrams, and classification of igneous rocks based on total alkalis vs. silica.

This 24-slide PowerPoint presentation describes the classification of metamorphic rocks using texture and composition. Foliation, lineation, cleavage, schistosity, gneissose structure, hornfels, and granofels are discussed. Specific metamorphic rock types and modifying terms (porphyroblastic, spotted, augen, para-, ortho-) are defined and photographs of some are provided.

This set of lecture notes about contact metamorphism contains information on contact aureoles, isograds, thermal conductivity, and latent heat of crystallization. Albite-epidote hornfels, hornblende hornfels, pyroxene hornfels, and sanidinite facies are presented. Skarns are also discussed. A number of ternary diagrams and illustrations are included.

This 32 slide PowerPoint presentation presents a list of alkaline rocks followed by an in depth look at continental alkaline magmatism of the East African Rift system. A chemical, geographic, and structural look at carbonatites follows. The presentation progresses through discussions of lamproites, lamprophyres, and kimberlites.

This 27-slide PowerPoint presentation contains a number of schematic diagrams showing continental arc settings. Chemical comparisons of various continental arc magmas are discussed using isotopic variation and the occurrence of rare earth elements. The presentation also covers isotopes, rare earth element characteristics, and the geographic occurrence of plutonic arcs.

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 site is a lecture by Dr. Stephen Nelson from Tulane University that explores the use of the Miller Index notation to designate crystal forms. Topics include crystal forms, general and special forms, and open and closed forms. Also discussed is the relationship between form and crystal faces, along with zones and zone symbols, the vectorial properties of crystals, and crystal habit. Tables and illustrations accompany the text.

This site is a lecture from Tulane University that explores the symmetry observed in crystals. Topics covered include crystallographic axes, the crystal lattice, and unit cells. Tables and illustrations accompany the text.

This site is a lecture by Dr. Stephen Nelson from Tulane University that discusses crystallographic calculations. Topics include a review of Miller indices, axial ratios, angles corresponding to a Miller Index, and angles between crystallographic axes in monoclinic or triclinic systems. Step by step examples of the calculations are provided, including associated illustrations and diagrams.

This module addresses how to determine the size of a ton of rock of a given composition and invites the student to figure out how to solve the problem. Students recreate spreadsheets, shown in a Powerpoint module, on their own with formulas that answer various pieces of the overall question. This module is the third in a series of six that examine the density of planets and rocks, and was designed for an undergraduate class where students look at geological questions mathematically and may spend more time on the math than on the geology. The site includes teaching notes and tips, and links to teaching materials and additional resources.

This OLogy reference list has nine kid-friendly books on Earth science. A short description is given for each title, along with author name and publisher.

This site is a lecture by Dr. Stephen Nelson from Tulane University that explores the 32 possible combinations of symmetry operations that define the external symmetry of crystals. The lecture defines the six crystal systems (triclinic, monoclinic, orthorhombic, tetragonal, hexagonal, and isometric) and explains the derivation of the Hermann-Mauguin symbols (also called the international symbols) used to describe the crystal classes from the symmetry content. Tables and illustrations accompany the text.

This is a collection of 18 geology exercises that are designed for teachers with little or no geology background. Each exercise includes relevant background information, complete instructions, student handouts and answer keys. Topics include rock and mineral identification, Bowen's reaction series, crystal models, topographic maps, earthquakes, groundwater, oil exploration, plate tectonics and more.

This lesson provides an introduction to the use of natural gas as an energy source. Topics include its advantages (cleanliness, fewer carbon emissions), disadvantages (difficulty in transport and storage), sources, and usage.

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.
