For complex rocks in which the structure of minerals, rather than their chemical composition, changes with progressive evolution of the system, it makes sense to.
Stable atomic structures of minerals can be explained to a large extent by the 5 rules of Linus Pauling--Pauling's rules and the principles of ionic substitution.

Molecular orbital calculations employing the SCF-X" scattered-wave cluster method have been used to model the electronic structures of the thiospinel minerals.
A mineral is a solid, inorganic, naturally-formed substance that has a crystalline structure and specific chemical composition I know that's a lot to take in, so let's.
Investigators have found, however, that chemical composition alone is insufficient for classifying minerals Determination of internal structures, accomplished.
