This is always the case in a decomposition reaction. Don't forget that!! Figuring out what the products are in decomposition is harder (maybe you'll think it's easier!!) because you will have to recognize several categories of decomposition reactions.
Geology. a small, usually spherical cavity in a rock or mineral, formed by expansion of a gas or vapor before the enclosing body solidified. Origin of vesicle.
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 causeâ¦s gasses dissolved in the molten material to come out of solution or exsolve.
