During a mountain building phase, the sedimentary rocks may be buried deeply and subjected to heat and pressure causing certain minerals to form which were not present in the original rock.
Also, an igneous intrusion may cause adjoining sediments to be altered in a contact metamorphism leading minerals such as garnets to form.
A metamorphic rock. A metamorphic rock is ANY type of rock that gets changed by heating and squeezing.
Pressure compresses the sedimentary and igneous rock(s) tightly and forms metamorphic rock.
Marble is the most common metamorphic rock formed from the parent rock of limestone.
Metamorphic rock can be formed from all three rock types: sedimentary, igneous, and even other metamorphic rock.

Is chalcopyrite metamorphic sedimentary or igneous?
Chalcopyrite is primarily an igneous mineral, formed in hydrothermal veins through the crystallization of hot, metal-rich fluids. It can also occur in sedimentary rocks as a secondary mineral. Metamorphic rocks may contain chalcopyrite if it was present in the original rock or introduced during metamorphism.
How are sedimentary and metamorphic rocks similar and different?
They are both rocks. Sedimentary can contain metamorphic rocks. and vice versa.
What type of rocks weather and erode to form sedimentary rocks?
Igneous, metamorphic, and existing sedimentary rocks can weather and erode to form sedimentary rocks. Igneous and metamorphic rocks can break down into sediments through processes like weathering and erosion, which then may accumulate and lithify into sedimentary rocks. Existing sedimentary rocks can also be reworked and lithified to form new sedimentary rocks through processes like compaction and cementation.
Metamorphic rocks that don't have layers?
Metamorphic rocks without visible layering are typically formed under conditions of high temperature and pressure that cause the minerals within the rock to recrystallize. This may result in a homogeneous texture without distinct layers or bands. These rocks may still exhibit foliation or other textures that indicate their metamorphic origin, even if they lack visible layering.
What is the difference between sedimentary and metamorphic rocks?
Sedimentary rocks are formed from the accumulation and compression of sediments, while metamorphic rocks are formed from the alteration of existing rocks due to heat, pressure, or chemical reactions. Sedimentary rocks are typically layered and can contain fossils, while metamorphic rocks have a more crystalline structure and may exhibit foliation.
What rock can be broken into fragments that may later form sedimentary rocks?
Any rock (igneous, sedimentary or metamorphic) may be broken into fragments that may later be formed into sedimentary rock.
What features of metamorphic rocks are unlikely to be found in sedimentary rocks?
Foliation, a layered or banded texture, is a common feature of metamorphic rocks but not typically found in sedimentary rocks. Metamorphic rocks can also have mineral reorganization and recrystallization that are not commonly seen in sedimentary rocks. Additionally, metamorphic rocks may exhibit distinct metamorphic minerals like garnet, staurolite, or kyanite, which are unlikely to be found in sedimentary rocks.
Is there a difference between metamorphic rocks and inclined sedimentary rocks?
Yes, the main difference is between a sedimentary rock and a metamorphic rock.A sedimentary rock is formed from various sizes of rock or rock particles (eroded from older rocks) that have been deposited by wind or water over time. The weight and pressure of subsequent deposits results in the squeezing out of water from the lowest depositional layers, and these layers may become cemented together as a solid rock.Metamorphic rocks are formed subjecting an existing rock (sedimentary or volcanic), to heat and or pressure after it was formed. This 'cooking' changes the rock, giving it new fabrics, textures and minerals.Both sedimentary and metamorphic rocks can be inclined with respect to their fabrics (beading in the case of sedimentary rocks), this is not a distinguishing feature.
Is chalcopyrite metamorphic sedimentary or igneous?
Chalcopyrite is primarily an igneous mineral, formed in hydrothermal veins through the crystallization of hot, metal-rich fluids. It can also occur in sedimentary rocks as a secondary mineral. Metamorphic rocks may contain chalcopyrite if it was present in the original rock or introduced during metamorphism.
How are sedimentary and metamorphic rocks similar and different?
They are both rocks. Sedimentary can contain metamorphic rocks. and vice versa.
What features of sedimentary rocks are unlikely to be found in metamorphic rocks?
Sedimentary rocks often contain fossils, sedimentary structures (such as bedding or ripple marks), and may exhibit layering (stratification) due to deposition. These features are unlikely to be found in metamorphic rocks as they form under high temperatures and pressures, which can obliterate such original sedimentary features.
What type of rocks weather and erode to form sedimentary rocks?
Igneous, metamorphic, and existing sedimentary rocks can weather and erode to form sedimentary rocks. Igneous and metamorphic rocks can break down into sediments through processes like weathering and erosion, which then may accumulate and lithify into sedimentary rocks. Existing sedimentary rocks can also be reworked and lithified to form new sedimentary rocks through processes like compaction and cementation.
How you can tell an igneous rock from a sedimentary rock from a metamorphic rock?
Igneous rocks form from the cooling and solidification of molten rock (magma/lava), sedimentary rocks form from the deposition and lithification of sediment particles, and metamorphic rocks form from the alteration of pre-existing rock due to heat and pressure. Igneous rocks often have a crystalline texture, sedimentary rocks may contain layers or fossils, and metamorphic rocks often have foliated or banded textures.
Is gneiss metamorphic?
A gneiss is a metamorphic rock. Metamorphic rocks are created by the alteration of rocks by heat and pressure. Therefore, a gneiss may be created from an igneous rock in which case it would be called an orthogneiss.
Is a sedimentary rock or a metamorphic rock harder to sculpt?
Metamorphic rocks are formed from sedimentary and igneous rocks. When sedimentary or igneous rock is subjected to heat and pressure, the rock gets compressed. Therefore, if you had the same amount of metamorphic rock and sedimentary or igneous rock, the metamorphic rock would be heavier, because there is more 'stuff' in the metamorphic rock. ---------------------------------------------- However please note: There are types of igneous rocks that are hard (eg granite) and others that are soft (eg volcanic ash). There are types of metamorphic rocks that are hard (eg gneiss) and others that are soft (eg marble). Thus "hardness" is not a characteristic that can be used to distinguish between the two.
Metamorphic rocks that don't have layers?
Metamorphic rocks without visible layering are typically formed under conditions of high temperature and pressure that cause the minerals within the rock to recrystallize. This may result in a homogeneous texture without distinct layers or bands. These rocks may still exhibit foliation or other textures that indicate their metamorphic origin, even if they lack visible layering.
