What is the texture of cooling magma?
Cooling magma can have a variety of textures, depending on factors like mineral content, cooling rate, and the specific type of magma. Common textures include aphanitic (fine-grained), phaneritic (coarse-grained), porphyritic (mixed grain sizes), glassy (amorphous), or vesicular (with gas bubbles). Each texture provides clues about the conditions under which the magma cooled and solidified.
What texture does a volcanic rock have?
Textures of volcanic rocks include aphantitic (mineral grains are present but microscopic) , porphyritic (some grains are visible to the naked eye), glassy (all or much of the rock lacks a crystalline structure), and vesicular (solidified gas bubbles are present).
Why the vesicular texture is not associated with peridotitea?
Vesicular texture is characterized by the presence of small gas bubbles or vesicles formed during the cooling of magma. Peridotite, being an ultramafic rock primarily composed of olivine and pyroxene, typically forms at greater depths within the Earth's mantle where the pressure is high, preventing the formation of gas bubbles. Consequently, the cooling of peridotite occurs in a solid-state, leading to a dense, granular texture rather than a vesicular one. Thus, vesicular textures are more commonly associated with volcanic rocks that cool rapidly at the surface, allowing gas to escape and form vesicles.
What is the meaning of vesicular?
Of or pertaining to vesicles; esp., of or pertaining to the air vesicles, or air cells, of the lungs; as, vesicular breathing, or normal breathing, in which the air enters freely the air vesicles of the lungs., Containing, or composed of, vesicles or vesiclelike structures; covered with vesicles or bladders; vesiculate; as, vesicular coral; vesicular lava; a vesicular leaf., Having the form or structure of a vesicle; as, a vesicular body.
What is vesicular texture?
Vesicular texture refers to a specific type of rock texture characterized by the presence of small cavities or vesicles, which are formed by trapped gas bubbles during the solidification of volcanic lava. This texture is commonly found in volcanic rocks such as basalt and pumice, where the rapid cooling of lava allows gases to escape, leaving behind these empty spaces. The size and distribution of vesicles can vary, influencing the rock's overall appearance and density. Vesicular textures often indicate the explosive nature of the volcanic eruption that produced the rock.

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 are different textures of tongue?
The tongue can have various textures including smooth, rough, bumpy, and furry. These textures can be influenced by factors such as dehydration, oral health, microbial imbalance, or medical conditions like geographic tongue or oral thrush. It's important to consult a healthcare professional if you notice any unusual textures on your tongue.
Why vesicular texture is associated with peridotites?
Peridotites are invasive rocks formed underneath the earth's surface and the high pressure conditions Dodge gases from forming and getting away
How heavy is is vesicular basalt compared to a meteorite?
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.
