In the world of mineralogy, predictability is key, which is why solid crystals like ice are called "minerals".There are still a lot of solid materials out there that do not meet the definition of crystal. A good example is glass. Most glass is made of silica, which has the formula SiO 2.However, most glass is also an amorphous solid meaning that it has no predictably …Web

Minerals are naturally occurring solid objects. They aren't even alive. A crystal is formed by fitting the atoms that make up a mineral together. While impurities or non-crystalline matter may be present, the chemical structure, or types of atoms in a given kind of crystal, is the same for all crystals of that kind.Web

Any existing open space between mineral grains in a rock can potentially contain a fluid. This fluid is mostly H2O, but contains dissolved ions. The fluid phase is important because chemical reactions that involve changing a solid mineral into a new solid mineral can be greatly speeded up by having dissolved ions transported by the fluid.Web
