Different learning resources categorise quartz differently. Strictly speaking, is quartz a silicate mineral or an oxide mineral?
2 Answers
Quartz is a silicate at the most used Dana and Strunz classifications of minerals.
Several websites and mineralogists classify it as silicate.
The structure of quartz is similar to other silicates with Si-O tetrahedres.

quartz a silicate mineral or an oxide mineral
Both. The two are not mutually exclusive.
Quartz is an oxide, because it is an oxide of the element silicon.
Quartz is also a silicate, because it is composed of a framework of silicate tetrahedra.
