* Vesicular rock texture is generally displayed in extrusive igneous rocks which contain many vesicles of trapped air, such as pumice or scoria.
* Igneous rocks containing holes which were produced as gases escaped from the upper part of lava flow.
If something has a homophonic texture then it has a chordal texture :)

Largely homophonic although there are lines of monophony.

It has a vesicular texture.
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.
A vesicular texture is one where there are small voids within the igneous rock. These tend to form in extrusive igneous rocks due to the loss of confining pressure which causes gasses dissolved in the molten material to come out of solution or exsolve. These gasses form bubbles within the cooling lava and can become trapped if the lava cools rapidly, leaving a permanent gas bubble or void space within the solidified igneous rock.
Yes. Pumice is so fine-grained, often times it's crystals are vesicular and glassy.
Lava rock with air pockets are known as vesicular lava rock. These air pockets are formed during the solidification process of lava, which traps gas bubbles within the rock. This gives the rock a porous and lightweight texture.
Obsidian is a type of volcanic rock that is extremely vesicular and glassy in appearance. It forms when lava cools quickly with minimal crystal growth, resulting in a smooth texture and shiny appearance.
Vesicular rocks contain lots of small cavities, usually filled with air. Non- vesicular ones don't have these holes. Vesicles are formed when magma suddenly rushes out on to the surface and its dissolved gases come out of solution, blowing bubbles in the liquid rock which are preserved as it cools quickly and sets. An example of a vesicular rock is pumice.
A vesicular igneous texture indicates that the rock contains numerous gas bubbles, or vesicles, formed during solidification. This texture typically occurs in volcanic rocks, such as pumice or scoria, where gases are released from the magma as it erupts. The presence of vesicles suggests that the lava cooled rapidly, allowing the bubbles to be trapped within the solidifying material. Overall, this texture provides insights into the explosive nature of the volcanic activity and the conditions under which the rock formed.
Scoria is a type of volcanic rock that is typically composed of small mineral grains, such as olivine, pyroxene, and plagioclase. However, the grains are generally not easily distinguishable due to the rock's vesicular (full of holes) and frothy texture, which is a result of gas bubbles trapped during the rock's formation.
The main types of rock texture are crystalline, fragmental, glassy, and vesicular. Crystalline rocks have interlocking mineral grains, fragmental rocks are made up of broken fragments of pre-existing rocks, glassy rocks have no crystal structure due to rapid cooling, and vesicular rocks have cavities or bubbles caused by gas escaping during solidification.
Peridotites are invasive rocks formed underneath the earth's surface and the high pressure conditions dodge gases from forming and getting away
No, scoria is not a metamorphic rock. It is a type of igneous rock that is formed from lava that has cooled quickly, resulting in a porous and vesicular texture. Metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure.
