☀️4 Vesicular Basalt Natural Stones☀️ ~1”-3” Occasionally, we find these most-curious pitted stones on the beaches. After some research, I'm glad I finally understand how they got that way. They are called "vesicular basalt," which means basalt with textures, and if the deep pits (vesicles) cover more than half the surface of the rock, it's called scoria. Vesicular basalt is an igneous rock that forms when gas bubbles become trapped in lava as it crystallizes, giving the rock a spongy, porous appearance. The term "vesicular" refers to the gas bubbles, or vesicles, that are trapped in the rock. The bubbles are formed when dissolved gases, such as water or carbon dioxide, separate from the magma as it moves toward the Earth's surface. The bubbles then open into each other and spheroidize, creating cavities in the rock
