Educational Links

This page provides a variety of educational materials related to geology and mineralogy.

The following are photo albums of different rock types with labels and geological information about them.

Igneous Rocks – rock formed through the solidification of magma or lava.  Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rock or on the surface as extrusive (volcanic) rocks.

Sedimentary Rocks – rock that is formed by deposition of material at the surface and within bodies of water.

Metamorphic Rocks – rock that is formed via metamorphism. The original rock (protolith) is subject to heat and pressure causing chemical & physical changes.

Additional photo albums may be found here
