Study the Formation of Different Igneous Rocks

Samples of Intrusive and Extrusive Igneous Rocks

This kit introduces students to igneous rocks.

Introduce your students to rocks formed from the cooling of magma and lava.

Includes: six each of obsidian, pumice, and basalt. Set of 18.

Common rocks and minerals for testing and identification studies are 2–3cm each.

Examine the Mineral Composition of Igneous Rocks

Coarse, 'salt and pepper': dark pyroxene and light andesine. Provides perfect representation of an intermediate igneous rock.

Classic, very coarse-grained igneous texture.

Represents a Wide Range of Depositional Environments and Rock Textures

Perfect for Introductory Lessons on Metamorphic Rocks.

An introductory rock set contains six samples from each of the three major rock types.

Grayish black trap rock.

Designed for Introductory College Petrography Labs

Includes: six each of conglomerate, sandstone and shale. Set of 18.

Common rocks and minerals for testing and identification studies are 2–3cm each.

The Premium Rock Collection features 12 palm-sized specimens representing all three rock types: igneous, metamorphic, and sedimentary.
