What is it about?
Pyrochlore supergroup minerals are fundamental to understand the role of oxides in geological systems and the synthesis of new materials. We set the new nomenclature scheme of classification based on the dominant valence at the crystallographic sites. Also, we present crystal structure considerations and detailed information about occurrences.

Why is it important?
It can inspire the synthesis of new materials with designed and improved physical properties. Also, it can help in the hunt for new mineral species.
Perspectives
Since 2010, more than 10 new mineral species were completely characterized and there are much more to be investigated. Since 2018, more than 1000 articles describing properties and applications of compounds with pyrochlore structure were published.
