Often, lava cools over a few days to weeks and minerals have enough time to form but not time to grow into large crystals. Basalt is the most common type of extrusive igneous rock and the most common rock type at the Earth's surface. Last modified June 17, 2003 by Lisa Gardiner.
Because such slow cooling allows time for large crystals to form, intrusive igneous rock has relatively large mineral crystals that are easy to see. Granite is the most common intrusive igneous rock (Figure 4.12). Figure 4.12: A close-up of a granite sample.he holes make pumice so light that it actually floats in water.
