Conclusions

This work is the first attempt to present a structural classification of the whole domain of minerals, and, like any pioneer work, it will certainly be incomplete and contain a number of errors. Its aim is to relate the mineral structures in a natural and easy way, and this is accomplished by a structural classification and the use of structural formulas. What is now required is to develop and improve the structural formulas, by revisiting works on structure determination of minerals, and to pay more attention to the new determinations in order to present complete structural descriptions.
