It's a mixture.
It is a rock type and most frequently would be categorized as a mixture (of minerals which are compounds made of elements). However a pure quartz sandstone would not be a mixture (it would be nearer a compound made of elements) because there would be only one mineral type present.
Stone can be a mixture, but it can also be a compound. It depends on the stone. If the stone consists of one element, it is not a mixture.
