Petrology of Igneous and Metamorphic Rocks - GLY
Spring Term, 2012
Keys for Final Examination and Lab Final are posted. Grades have been posted to the server on Wednesday, and will be available to students on Thursday. Exams may be picked up at my office.
Anyone with free time on their hands? We still have plenty of things to do concerning the move.....If interested, please see me.
Some of you have seen the illuminated hand lenses that Ed and Shea have. Shea sent me the following link, if you are interested. http://ascscientific.com/lens.html The lens is toward the bottom of the page.

Additional Information Sources
Crystals and Their Systems An illustrated article by Charles Lewton-Brain
- Crystallography branch
of the Mineral
database. Written by David Barthelmy, the Mineral Database contains a
wealth of useful information. The crystallography page contains links to pages
on each of the 32 crystal classes, including Java Applet Crystal Models,
available in both mono and stereo views. You can manipulate the models, and add
Miller Indices of the crystal faces. Models may be viewed in motion or
stationary, and may be seen in several different visual formats.
- Making Matter: The
atomic structure of materials A site featuring VRML "3-D" graphics to show
and discuss the structures of many materials, including several different types
of minerals and mineralogically important structures. There are discussions of
close packing, packing of different size atoms, examples of octahedral and
tetrahedral holes in structures, etc. Many common mineral structures are
shown. The site is in France, and viewing the structures requires large
downloads and VRML capability in your browser. Best to visit this site when the
Internet isn't too busy.
- Mineral Structure
Database From the Mineralogical Society of America - under construction,
Common, and Interesting Molecules 3-D representations of a number
of molecules, including a selection of minerals.
- Elements - An International Magazine of Mineralogy, Geochemistry, and Petrology
Mineral List A very comprehensive list of minerals, with more data than
most people will need.
Mineral Databases A series of databases, including mineral lists, mineral
search, and mineral pictures. They are developing a search engine for mineral
locations, an unusual feature. WARNING: The site may be very slow.
Keys Trying to identify an unknown mineral? There are a variety of keys
based on physical and optical data available at this site.
Gallery Data on minerals by name, by class, and by groupings (birthstones,
gemstones, etc.). Produced by Amethyst Galleries, Inc., a commercial site ("The
First Internet Rock Shop!").
- The Mineral and Gemstone
Kingdom An excellent general reference site, with mineral data, photos,
etc. Financed by some banner advertising, but not enough to be offensive.

illustrated with drawings of many structures.

Mineralogy Course Notes Dr. Greg Finn of Brock University, St. Catharines,
Ontario, has a complete set of lecture notes for a course in optical mineralogy
online. Diagrams explaining the physical principles behind optical mineralogy
are available, as well as photomicrographs illustrating many of the points
discussed. Excellent reference for those wanting to know more about the

web pages containing images of minerals in plane polarized and crossed Nicols,
as well as useful optical data about the mineral.

Stability and Phase Diagrams Prof. Stephen Nelson, Tulane University. Good
coverage of the topic, including the thermodynamics behind the subject.

summary of much of the material we covered on binary phase diagrams.
