Final answer:
Basalt is not an example of a rock type with very large crystals.
Step-by-step explanation:
False, basalt is not an example of a rock type with very large crystals. Basalt is a fine-grained igneous rock that is usually dark-colored and often found in lava flows. It is composed mainly of minerals like plagioclase feldspar and pyroxene, and it typically has a smooth texture due to its rapid cooling on the Earth's surface.
