Vesicular texture refers to a volcanic rock feature characterized by numerous cavities, known as vesicles, formed by trapped gas bubbles during the solidification of lava. This texture indicates a rapid cooling process and gas escape dynamics within the erupting magma, often seen in basalt and other extrusive igneous rocks.

Gas bubbles form when gas is trapped in a liquid or solid, creating a pocket of enclosed gas that can impact the physical properties and behavior of the material. They play significant roles in various scientific processes and applications, such as fermentation, decompression sickness, and foam formation in industrial applications.

Basalt is a dark, fine-grained volcanic rock that forms from the rapid cooling of low-viscosity lava rich in magnesium and iron. It is the most common rock type in the Earth's crust and is a major component of oceanic crust and volcanic islands.

Extrusive igneous rocks form from the rapid cooling of lava on the Earth's surface, leading to fine-grained textures due to the quick solidification process. These rocks are primarily found in volcanic regions and provide significant insights into the Earth's volcanic activity and the composition of the Earth's crust.
