Question

Sandstone metamorphises into _____________ .​

Answer 1

Answer:

Quartzite

Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts.

Answer 2

Answer:

Chert or flint may become a finely crystalline quartz rock; sandstones lose their clastic structure and are converted into a mosaic of small close-fitting grains of quartz in a metamorphic rock called quartzite.

Quartzite is composed of sandstone that has been metamorphosed. Quartzite is much harder than the parent rock, sandstone.
