Every mineral has a strict chemical formula. Although, practically the atoms or ions are not positioned perfectly to give the formula, hence they exist as mixtures.

Minerals are classified according to their composition
The composition of a rock is decided by the % of the constituent minerals and components contained inside it. The minerals that form up rocks have outlined chemical compositions and rigid atomic structures. once daylight strikes the rock's surface, the composition and atomic structure of the various minerals

Composition of minerals
A definite chemical composition
A. A geologist would study the composition of minerals.
Minerals are solid homogeneous inorganic substances having a specific chemical composition that can be represented by a chemical formula. They are different from rocks, which can be a mixture of minerals and non-minerals and do not have a specific chemical composition.
Minerals (other than elemental minerals) are combinations of elements.
These minerals are oxides.
