When the magma finally reaches the surface as lava and cools, the rock solidifies around the gas bubbles and traps them inside, preserving them as holes filled with gas called vesicles. Amygdaloids are simply vesicles that have been filled in with a secondary mineral long after the flow cooled. There are many types of basalt with different proportions of elements. Once outside, the hot lava cools very quickly as it comes into contact with either the air or ocean water. When the magma finally reaches the surface as lava and cools, the rock solidifies around the gas bubbles and traps them inside, preserving them as holes filled with gas called vesicles. When igneous rocks contain two distinct grain sizes, the texture is porphyritic, and the finer crystals are called the groundmass. No need to register, buy now! The basalt flows belong to the Arabian Harrat volcanism. It may be compact or vesicular (porous) because of gas bubbles contained in the lava while it was cooling. This causes the magma to foam up, and the resulting rock to be riddled with hole-like structures called vesicles. Basalt with a vesicular texture is called vesicular basalt, when the bulk of the rock is mostly solid; when the vesicles are over 1/2 the volume of a specimen, it is called scoria.
