What does sand turn into when under high pressure and high temperature?
When sand is subjected to high pressure and high temperature, it can transform into a type of metamorphic rock called quartzite. Quartz grains in the sand recrystallize and fuse together under these conditions, resulting in the formation of a hard, compact rock with a granular texture.
What type of metamorphic rock would be produced by sand?
Sand would likely metamorphose into quartzite, a metamorphic rock made predominantly of quartz. Sand is primarily composed of quartz grains, and under heat and pressure, these grains can recrystallize and compact to form quartzite.
What eventually happens to a grain of sand?
A quartz sand grain could combine with other rock particles to become sandstone which could then undergo metamorphism to become quartzite. Given enough time and weathering, it could simply become a part of a solution that reconstitutes elsewhere as part of a mineral crystal.
Is quartzite course grained or fine grained?
Quartzite is typically coarse-grained, with individual grains visible to the naked eye. This is because quartzite is formed by the metamorphism of sandstone, where the original sand grains recrystallize into larger grains.
How is quartzite obtained?
Quartzite is a metamorphic rock that forms when sandstone (which is composed largely of quartz) is subjected to high heat and pressure without undergoing melting. Since it is composed primarily of quartz, it shares the properties of quartz, such as high hardness.

What did quartzite used to be?
Quartzite used to be quartz sand, generally well sorted and quite pure. Quartz has a great propensity to crystallize, so sand grains will tend to bind together.

Why is quartzite very hard and more resistent than its parent rock?
Quartzite is a nonfoliated metamorphic rock that formed by the metamorphism of pure quartz sandstone. The intense heat and pressure of metamorphism causes the quartz grains to compact and become tightly intergrown with each other, resulting in very hard and dense quartzite.

Why is sand not as fast at melting ice as salt?
Sand isn't used for melting snow. Sand is used for traction.

What do you get by melting sand?

What is the metermophic equivalent of sand stone?
The metamorphic equivalent of sandstone is quartzite. Sandstone is composed of sand-sized grains of mineral or rock fragments, while quartzite forms from the metamorphism of sandstone through intense heat and pressure, resulting in a rock that is predominantly composed of quartz.
What type of metamorphic rock is formed by sand?
Sand forms sedimentary rocks such as sandstone. Sandstone containing mostly quartz can form the metamorphic rock quartzite.
How does metamorphism change sandstone?
Sandstone can metamorphose into quartzite.
