Rocks and minerals are the building blocks of our dynamic planet. They form the landscape and provide us with valuable resources. By studying rocks and minerals we can better understand the events that shaped and continue to shape the Earth.

Minerals are naturally occurring chemical compounds that have been formed by geological processes. Minerals also provide chemicals that are essential for life on Earth.

Most rocks are mixtures of different minerals. They show remarkable variations in texture and composition, depending on how they formed.
