Product Overview
Commonly found as magmatic intrusions in the crust, granite forms slowly in shallow or evolved magma chambers. The large crystals are indicative of a slow cooling rate, and make mineral identification simple. Ideal for teaching students about rounding and sorting, as well as for identification & classification exercises. This classic igneous rock is a must-have sample when discussing rock types, the rock cycle, and the rock formation.
While each specimen will vary slightly in shape, size and color, it will measure approximately 1" in length. Pack of 12. Each set is individually packaged, labeled & barcoded for easy identification and storage.
