Answer 1

Answer:

quartzite is a metamorphic rock that comes out from sandstone which is a sedimentary rock under intense heat and pressure. Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone.

Answer 2

$\huge{\mathfrak{\underline{\red{Answer}}}}$

Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of iron oxide (Fe2O3).
