Basal igneous rocks are what?

Answer 1

Basaltic igneous rocks, commonly referred to as basalt, are dark-colored, fine-grained volcanic rocks primarily composed of plagioclase feldspar and pyroxene. They form from the rapid cooling of lava at or near the Earth's surface, resulting in their characteristic dense and solid structure. Basalt is the most abundant volcanic rock on Earth and is often found in oceanic crust and volcanic islands. Its formation is typically associated with divergent tectonic boundaries and hotspot volcanism.
