The quartzite extraction process generates the quartzite waste (or quartzite residues or quartzite tailings) (QTZ). ... The authors tested various grinding processes and defined that the fraction below 0.417 mm was suitable for mortars, whereas the particles greater than 0.417 mm should be used for precast concrete elements.

Here is the key point: The heat and pressure that turn sandstone to quartzite is not a definitive, black-and-white occurrence. It's a gradual process, with subtle differences occurring all along the spectrum. There is no exact moment that sandstone becomes quartzite. It's similar to the way that colors blend from one shade to the next.
