What Happens When Sandstone is Metamorphosed?

When sandstone is metamorphosed, what is the metamorphic product?

a) marble
b) schist
c) limestone
d) phyllite
e) quartzite

Final Answer:

Sandstone, a sedimentary rock, undergoes metamorphism to transform into quartzite.

Sandstone, a sedimentary rock composed of sand-sized minerals and rock grains, can transform into a different type of rock through the process of metamorphism. When subjected to intense heat and pressure, sandstone undergoes metamorphism to become quartzite, a harder and denser metamorphic rock. This transformation occurs due to the geological activity within the Earth's crust.

During the metamorphic process, the mineral composition, texture, and structure of sandstone change to form quartzite. Quartzite is known for its durability and resistance to abrasion, making it a popular choice for applications that require a durable and attractive stone. The formation of quartzite involves recrystallization of the sandstone grains and the development of interlocking quartz crystals.

Overall, the metamorphism of sandstone into quartzite is a natural process that highlights the dynamic nature of rocks and minerals in response to changes in their environment.
