What else can I help you with?
Sandstone and basalt are changed by heat and pressure to form?
Sandstone is changed into quartzite and basalt is changed into schist or gneiss through the process of metamorphism.
WHAT IS The original rock before it metamorphoses?
The original rock before it undergoes metamorphism is called a protolith. This protolith can be any type of pre-existing rock, such as shale, sandstone, or granite, that is subjected to heat, pressure, and chemical changes to form a metamorphic rock.
What is prograde metamorphism?
Prograde metamorphism refers to metamorphic processes that occur as rock is buried deeper in the Earth's crust and experiences increasing temperature and pressure. This leads to changes in mineral composition and texture as the rock undergoes metamorphism.
What is sandstone after metamorphism?
After metamorphism, sandstone transforms into a rock called quartzite. This process occurs under high temperature and pressure, which causes the quartz grains in the sandstone to recrystallize and fuse together, resulting in a denser and more durable rock. Quartzite typically exhibits a grainy texture and can come in various colors, depending on the mineral content and impurities present during its formation. The metamorphic process enhances its strength and resistance to weathering compared to its parent sandstone.
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 kind of rock is produced when sedimentary sandstone undergoes metamorphism?
When sedimentary sandstone undergoes metamorphism, it can transform into a metamorphic rock called quartzite. Quartzite is a hard, non-foliated metamorphic rock composed almost entirely of quartz grains that have recrystallized during the metamorphic process.
How does sandstone gets converted to quartzite?
Quartzite is the metamorphic product of sandstone. During metamorphism, intense heat and/or pressure cause the quartz grains contained in the sandstone grow and recrystallize, interlocking together creating Quartzite.
What metamorphic rock is formed from sandstone?
Sandstone can be metamorphosed into quartzite. Heat and pressure bake the sandstone and it becomes extremely hard.
Does limestone become marble?
Yes. When it undergoes metamorphism.
Sandstone and basalt are changed by heat and pressure to form?
Sandstone is changed into quartzite and basalt is changed into schist or gneiss through the process of metamorphism.
What metamorphic rock will limestone turn into if it undergoes contact metamorphism?
If limestone undergoes contact metamorphism, it will typically turn into marble. Marble forms from the recrystallization of limestone under high temperature and pressure conditions.
During the intrusion of the Palisades Sill contact metamorphism changed sandstone and shale into what?
During the intrusion of the Palisades Sill, contact metamorphism changed sandstone and shale into quartzite and hornfels. Quartzite forms from the recrystallization of quartz sandstone, while hornfels forms from the alteration of shale due to high temperatures and pressures near the igneous intrusion.
What is metamorphic quartz sandstone?
Metamorphic quartz sandstone is a type of sedimentary rock that has undergone metamorphism, resulting in a denser, harder rock. This process typically involves heat and pressure that recrystallizes the quartz grains and other minerals in the sandstone, transforming it into a more compact and durable rock. Metamorphic quartz sandstone usually exhibits distinct banding or foliation due to the rearrangement of mineral grains during metamorphism.
When limestone undergoes metamorphism it produces which metamorphic rock?
When limestone undergoes metamorphism, it produces the metamorphic rock called marble. This process involves recrystallization of the calcite mineral in limestone to form interlocking crystals of calcite in marble.
Which two kinds of adjoining bedrock would most likely have a zone of contact metamorphism?
shale and sandstone
WHAT IS The original rock before it metamorphoses?
The original rock before it undergoes metamorphism is called a protolith. This protolith can be any type of pre-existing rock, such as shale, sandstone, or granite, that is subjected to heat, pressure, and chemical changes to form a metamorphic rock.
What does sandstone change to?
That depends on what happens to it. If it is sufficiently heated and compressed it will metamorphose to quartzite.
