General Collections

Rocks and Rock-Forming Minerals Collection

A basic study and reference collection including six rock-forming minerals, six igneous rocks, six sedimentary rocks, and six metamorphic rocks. Contains 24 numbered 1-1/4" natural specimens, compartmentalized container, and Rocks and Min... More.

Nasco Rock Collection

This is a basic study and reference collection, containing five igneous rocks, five metamorphic rocks, and five sedimentary rocks. Specimens include obsidian, granite, basalt, scoria, rhyolite, sandstone, limestone, shale, travertine, conglomerate, slat... More.

Igneous Rocks Collection

Representative specimens of intrusive and extrusive igneous rocks are included in this set. These materials provide a basis for understanding geologic processes such as volcanic activity at work in the earth. Contains 15 numbered 1-1/2" natural ... More.

Metamorphic Rocks Collection

In geologic processes usually associated with pressure and heat, igneous, sedimentary, and other metamorphic rocks may be reformed to become new metamorphic rocks. These important processes are better understood through study of representative metamorph... More.

Sedimentary Rocks Collection

The erosion and degradation processes which are at work on all materials exposed on the earth’s surface produce sediments which become reconsolidated through compaction and precipitation. Representative sedimentary end products compose this study ... More.

North American Collection

This collection represents important rock types and associations on the North American continent. The set contains 50 specimens with each of the igneous, metamorphic, and sedimentary groups strongly represented. It is an adequate collection for all aspe... More.

Classroom Collection of Rocks and Minerals

This collection provides materials for a basic study in mineralogy with specific study units essential to understanding general geology with these study groups: rock-forming minerals; igneous, sedimentary, and metamorphic rocks; ores of common metal... More.

Washington School Collection

Study units are present under these headings: rock-forming minerals; ore-forming minerals; industrial minerals; and igneous, sedimentary, and metamorphic rocks. Contains 40 numbered 2" x 1-1/2" natural specimens, compartmentalized co... More.

Washington Student Collection

This collection is designed to accompany the Washington School Collection (SB46078M). Unlabeled chips similar to the specimens in SB46078M are provided for individual study and comparison. Contains 40 unlabeled, natural specimens in a plastic bag. More.

Introductory Earth Science Collection

This basic unit of 75 rocks and minerals is designed to demonstrate the major rock-forming minerals; minerals in the scale of hardness; and recognized physical properties of minerals (i.e., streak, luster, cleavage and fracture, and specific gravity... More.
