Welcome to the McMaster Virtual Geology Museum

Discover rocks, minerals and fossils collected from around the world.  Take some time to learn the basics of rocks and minerals, browse our course samples, and explore some highlights of our Special Collections.

Geology Basics

Explore rudimentary rocks, minerals, and fossils in our galleries

 Minerals

A mineral is a naturally occurring inorganic substance with a definite chemical composition.  Explore minerals in our mineral gallery.

Igneous Rocks

Igneous rocks form from the cooling and solidification of magma (below the earth’s surface – intrusive rocks) or lava (above the earth’s surface – extrusive rocks).

Sedimentary Rocks

Sedimentary rocks form from the lithification of sediment, precipitation from solution, or consolidation of the remains of plants and animals.

Metamorphic Rocks

Metamorphic rocks form from the transformation of pre-existing rock into new rock as a result of high temperatures and/or pressures.

Invertebrate Fossils

A fossil is evidence of a plant or animal from a previous geologic period preserved in the earth’s crust.  Explore common invertebrate fossils in our fossil gallery.
