Vesicular basalts are usually felsic, with a SiO2 content greater than 69%. They may also contain sodium, aluminum, potassium, oxygen, hydrogen, and iron.
Vesicular basalt is a type of volcanic rock with a porous texture that contains numerous cavities (vesicles) formed by gas bubbles trapped during the solidification of lava. These cavities give the rock a lightweight appearance and may be filled with secondary minerals like quartz or calcite. Vesicular basalt is commonly found in volcanic regions and can be used as a building material or for decorative purposes.
Basalt is typically found in the form of columns, hexagonal prisms, or blocky shapes. These formations are a result of the rapid cooling of lava flows or volcanic eruptions. Basalt can also occur as amorphous masses or vesicular textures, depending on the cooling rate and composition of the lava.
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.
Basalt and gabbro have higher chemical weathering rates than rhyolite and granite because they contain more ferromagnesian minerals like olivine and pyroxene that are more susceptible to chemical weathering compared to the quartz-rich minerals in rhyolite and granite. This makes basalt and gabbro more prone to breakdown and alteration when exposed to weathering agents like water and acids.
Some common igneous rocks that form on or very near Earth's surface are basalt and scoria. Basalt is a fine-grained rock that often originates from volcanic eruptions, while scoria is a more vesicular or bubble-rich rock that forms from rapidly cooling lava on the surface.
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.

== == 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.
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.
Yes, basalt can contain bubbles, which are known as vesicles. These bubbles form when gases trapped in the molten rock escape as it cools and solidifies. The presence and size of vesicles can vary depending on the cooling rate and the amount of gas released during the eruption. Basalt with a high density of vesicles is often referred to as vesicular basalt.
A rock with little to no grain development and a vesicular texture is typically called a vesicular rock. It is formed from a volcanic eruption, where gases trapped in the lava create bubbles or vesicles. The most common example is vesicular basalt.

Basalt is a type of igneous rock that is formed from the cooling and solidification of lava. It is considered a chemical sedimentary rock, as its minerals crystallize directly from magma and do not involve the accumulation of organic or clastic material.
Basalt is typically found in the form of columns, hexagonal prisms, or blocky shapes. These formations are a result of the rapid cooling of lava flows or volcanic eruptions. Basalt can also occur as amorphous masses or vesicular textures, depending on the cooling rate and composition of the lava.
