Igneous Rocks
Rock specimens are useful for studying textures, grain sizes, and other features altered by pressure, temperature, and other natural forces. Different select categories of rock specimens are available for purchase as well, including metamorphic, igneous, and sedimentary rocks. Sets of rock specimens are housed in compartmentalized collection boxes, with descriptions of each specimen printed for easy confirmation of identification. These rock specimens are carefully selected to be the highest quality to provide students with a suitable introduction to earth materials and their characteristics.
