It would be classified as the metamorphic rock quartzite.
quartzite
A quartz sandstone is a sedimentary rock that contains >95% quartz sand. Other typical minerals present in this rock feldspars, accessory minerals and lithic fragments, depending on the source lithology of the sandstone. So when a quartz sandstone gets metamorphosed the rock is still composed of mostly quartz. The quartz grains are recrystallized into interlocking patterns with the impurities often discoloring the sample or causing subtle streaking. This new rock is then called a quartzite. It is important to distinguish that in almost all cases, rocks are composed of more than one mineral. Common exceptions to this are evaporites like gypsum.
The particles in quartz sandstone have travelled further before deposition due to their increased resistance to weathering factors.
Metamorphic. Original form: sandstone (sedimentary).
Sandstone is a clastic sedimentary rock that is made up of cemented sand grains (usually quartz ) thank you for asking that as that was i was thinking be3fore i went to a museum
quartzite
Sandstone. Whereas sandstone relies on cementing minerals of various types to hold it together, quartzite is held together by an interlocking mosaic of mostly recrystallized quartz , making it one tough rock.
rock salt and conglomerate
Sandstone is made up mostly of sediments of quartz and/or feldspar. Therefore sandstone is a clastic sedimentary rock.
Quartz sandstone, aka arenite, can form the metamorphic rock called quartzite.
Sandstone is not an igneous rock; it is a coarse-grained, sedimentary rock composed mostly of quartz.

Quartz is predominate.
Sandstone is a type of clastic sedimentary rock with sand-sized minerals or sand grains. Its two chief minerals are quartz and feldspar.
Chemically, a quartz sandstone is different than a calcitic marble. Additionally, they are classified differently by their method of formation. Sandstone is a sedimentary rock, and marble is a metamorphic rock. Sandstone has cemented grains, and marble has interconnected crystals.
conglomerate, quartz sandstone, siltstone
The particles in quartz sandstone have travelled further before deposition due to their increased resistance to weathering factors.
