Q112 (NDA-I/2026) Geography › World Physical Geography

Quartzite is metamorphosed from which one of the following rocks?

Result
Your answer: —  Â·  Correct: C

Explanation

Quartzite is a hard, non-foliated metamorphic rock which was originally pure sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression. During metamorphism, the individual quartz grains recrystallize along with the former cementing material to form an interlocking mosaic of quartz crystals.

  • Limestone is a sedimentary rock that metamorphoses into marble.
  • Shale is a sedimentary rock that typically metamorphoses into slate, and with further heat and pressure, into phyllite, schist, or gneiss.
  • Pegmatite is an igneous rock characterized by very large crystals; it is not the parent rock of quartzite.
