Is quartzite a metamorphic rock?
Yes, quartzite is a metamorphic rock that forms from the metamorphism of quartz-rich sandstone. Through the process of recrystallization, the quartz grains in sandstone become fused together to create a harder and more durable rock known as quartzite.
Why is quartile very hard and more resistant than its parent rock?
Quartzite is harder and more resistant than its parent rock, sandstone, because the process of metamorphism that forms quartzite involves recrystallization of quartz grains resulting in a more interlocking and compacted structure. This leads to a higher density and stronger bond between the grains, making quartzite more durable and resistant to weathering and erosion.
What sedimentary rock may become quartzite?
A sedimentary rock that may become quartzite is sandstone. Through the process of metamorphism, the sandstone can be transformed into quartzite, which is a hard, non-foliated metamorphic rock composed almost entirely of quartz crystals.
What is the parent rock of the nonfoliated metamorphic rock?
The parent rock of nonfoliated metamorphic rocks can vary, but some common examples include limestone, quartzite, and marble. These rocks typically form under high temperature and pressure conditions without the development of a layered texture like foliated rocks.
What does quartzite form from?
Quartzite forms from the metamorphism of sandstone. Under high pressure and temperature, quartz grains in sandstone recrystallize and fuse together, resulting in a hard, non-foliated metamorphic rock called quartzite.
