EISCO Porphyritic Granite Specimen (Igneous Rock), Approx. 1" (3cm) - Pack of 12
Brand: EISCO
Granite forms slowly in shallow or evolved magma chambers, and is also commonly found as magmatic intrusions in the crust. The large crystals are indicative of a slow cooling rate, and make mineral identification simple. Granite is a classic igneous rock, and is a must-have sample when discussing rock types, the rock cycle, and the formation, classification, and identification of igneous rocks.
