- 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 identification & classification exercises. This classic igneous rock is a must-have sample when discussing rock types, the rock cycle, and the rock formation. This set of six samples is excellent for group study and examination
- Each specimen is selected and hand processed, ensuring each sample exhibits defining features
- Sourced from a variety of locations around the world
- Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification
