Vesicular basalt has empty bubble-shaped holes, but were once filled with gas. These holes, called vesicles, form during the extrusion of magma to the surface.
Yes the Obsidian does cool quickly and the vesicular basalt
Vesicular basalts are usually felsic, with a SiO2 content greater than 69%. They may also contain sodium, aluminum, potassium, oxygen, hydrogen, and iron.
pumice is volcanic ash and it is vesicular. meaning that it has lots of air bubbles in it making it even lighter. basalt is hardened lava. it was exposed and cooled rapidly.
Volcanic rocks with gas bubbles are called vesicular. This, however, is a descriptive term rather than an actual rock types. Some vesicular volcanic rocks include pumice, scoria, and vesicular basalt.
Vesicles are rounded spaces that appear in igneous rocks from the solidification of the magma around gas bubbles. Pumice, scoria, and vesicular basalt are igneous rocks that contain vesicles.
Vesicular basalt has small rounded voids called vesicules formed by the molten rock cooling and freezing around pockets of gas. It looks a lot like a rock hard sponge. Non vesicular basalt is a normal solid rock.
A meteorite can be composed of different materials and so can vesicular basalt, but because of the presence of pores in vesicular basalt a meteorite would likely be heavier, assuming that they have the same volume.
the magma has a low content of gas
nothing

It could be vesicular basalt.
Vesicular basalt or pegmatite veins.
== == Igneous rocks have formed from molten material either above (extrusive) or below (intrusive) ground level. Extrusive igneous rocks include obsidian, basalt, and rhyolite; intrusive igneous rocks include gabbro and granite.

Mafic, infact it is often refered to as: "the mafic version of pumice"
