This web site includes almost 200 photomicrographs of rocks and minerals. All photographs are of thin sections ground to .03 mm thickness, in transmitted white light. Some show the appearance of minerals in plane polarized light, but most were taken with crossed polarizers on a petrographic microscope, better to illustrate mineral properties and rock textures. The majority of the pictures show a field ... Full description.

This slide show provides basic information on the three major rock types and the rock cycle. Diagrams of the rock cycle explain the processes and changes that connect the three rock types and illustrate how one type can be changed into another. Each of the three types (sedimentary, igneous, metamorphic) are described and illustrated with photographs. Addresses for websites with additional information ... Full description.

In this activity, students will learn to measure the density of various minerals. The activity will reinforce the usefulness of density as a physical test for identification of minerals. Using a selection of mineral specimens of varying densities, they will weigh each one in air, immerse it in a graduated cylinder of water, and measure the amount of water displaced by the specimen. Dividing the weight ... Full description.
