Close-up of porous rock, likely pumice or vesicular basalt. The surface is filled with variously sized holes, created by gas bubbles trapped during cooling and solidification. The texture is rough with a grayish color, characteristic of volcanic materials. The voids are irregularly shaped, ranging from small pinholes to larger cavities.
