What determines a mineral

Web13. The hardness of minerals is diagnostic because the hardness is determined by the strength of bonds and the structure of the mineral lattice. Hardness is basically the stress required to create and grow extended lattice defects such as micro-fractures, stress twins, and dislocations.

WebMinerals are the building blocks of rocks, and therefore are the building blocks of our planet's structure. They are specifically defined as naturally occurring, crystalline (as used in mineralogy, this means that they have an ordered internal structure) solids that are made inorganically, not by biological methods. WebLet's make a checklist. First, a mineral is a solid. In other words, a mineral cannot be a liquid or a gas. See, this quartz crystal is solid. Second, a mineral is made up of consistent ingredients called atoms. In the case of quartz, quartz is made up of two kinds of atoms called silicon and oxygen. Third on our checklist, a mineral has to be ...

WebSpecific gravity is the ratio between the mass (weight) of a mineral and the mass (weight) of an equal volume of water. A mineral's specific gravity (SG) can be determined by dividing its weight in air by the weight of an equal volume of water. For instance, quartz with a density of 2.65 is 2.65 times as heavy as the same volume of water.
