What is vesicular texture?

Vesicular texture refers to a specific type of rock texture characterized by the presence of small cavities or vesicles, which are formed by trapped gas bubbles during the solidification of volcanic lava. This texture is commonly found in volcanic rocks such as basalt and pumice, where the rapid cooling of lava allows gases to escape, leaving behind these empty spaces. The size and distribution of vesicles can vary, influencing the rock's overall appearance and density. Vesicular textures often indicate the explosive nature of the volcanic eruption that produced the rock.
