The vesicles in some basalts are remnants of bubbles of trapped gas.
basalt is an extrusive rock which means it is formed outside the earths crust when lava cools sometimes the gas bubbles in the lava are trapped in the main body of the rock as it cools but most of the gas gets to the top of the lava and is very bubbly and forms pumice

What are vesicles in an igneous rock?
Vesicles are small cavities or bubbles found within igneous rocks that are formed by gas bubbles trapped during the solidification of molten rock. These vesicles can vary in size and shape, and often become filled with minerals or other materials later on. They are commonly found in volcanic rocks such as basalt.
Is basalt a porous rock?
Yes, basalt is generally considered a dense and non-porous rock due to its fine-grained texture and low porosity. However, there can be variations in porosity depending on factors such as vesicles or fractures within the basalt.
What is Vesicular Basalt?
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.
How are basalt and granite diffrerent in their origin texture and mineral composition How are the similar?
Basalt is extrusive, formed from cooling lava, and has a fine-grained texture with minerals like pyroxene and plagioclase feldspar. Granite is intrusive, formed from cooling magma underground, and has a coarse-grained texture with minerals like quartz, feldspar, and mica. Both are igneous rocks, but basalt is dark-colored and dense, while granite is light-colored and less dense.
What are some facts about basalt?
Basalt is a dark-colored igneous rock that forms when low-silica lava cools on Earth's surface. It may commonly have vesicles. It often forms two types of lava flow: pahoehoe with smooth surfaces and a'a with rough surfaces. Basalt is commonly formed at mid-ocean ridges, oceanic hot spots, and in continental flood basalts.
Does basalt have bubbles?
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.
What is the difference between vesicular basalt and non vesicular basalt?
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.

What is the comparison of granite and basalt in terms of origin and texture which is intrusive and which is extrusive?
Basalt can't see crystals and basalt is extrusive. Granite you can see the crystals and is intrusive.

What are the spherical or elongated openings seen in many aphanitic rocks left by escaping gas bubbles as magma solidifies?
These are called vesicles, which are voids left by gas bubbles escaping from magma as it solidifies. They are commonly seen in aphanitic rocks like basalt and andesite.
What is Easter island made out of?
The island is dominated by Hawaiite and Basalt. It is known as a 'high island', an island of volcanic origin
A lava solidifies into nonvesicular basalt instead of vesicular basalt because?
The lack of vesicles in nonvesicular basalt suggests that the lava cooled and solidified quickly, which prevented gas bubbles from forming. This rapid cooling can occur when lava flows over a cold surface or when it is deposited underwater. As a result, the cooling process does not allow enough time for gas bubbles to form and become trapped within the rock, leading to the formation of nonvesicular basalt.

How can a basalt flow cause opal to form?
If the basalt flow contains air bubbles and pockets and there is a spring that contains silica then the silica can deposit into the air bubbles (the air bubbles are known as Amygdaloidal basalt or vesicles) If the silica deposits slowly and the conditions are correct then precious opal can form. Two examples of this would be in California at the Nowak and the Barnett mines.
