Do metamorphic rocks have different kinds of minerals from their parent rocks?
Of course they can. The overall compositions of the rocks will remain the same (assuming a closed system, which isn't always the case), but mineralogically there will be changes due to metamorphic pressures and temperatures. There are a whole list of minerals which only formed from metamorphic processes.
What are the two changes of a rock of metamorphism?
When rock changes into metamorphic rock, its appearance, texture, crystal structure, and mineral content change.
Is diamond an igneous or sedimentary rock?
Igneous, it is brought to the surface as an igneous Xenolith. The diamond crystal itself is of metamorphic origin it is metamorphosed carbon. It is more closely related to igneous rocks, as diamond forms in magma under very high temperatures and pressures, where there is no appreciable oxygen to burn the carbon. Artificial diamonds can be "grown" in a similar way by accumulating individual carbon crystals from a hot plasma (gas), in a process called chemical vapor deposition.
How can rock change from sedimentary to a metamorphic rock to igneous rock?
A short answer is that igneous may undergo crystalline restructuring and change under significant heat and pressure (though not enough to completely liquefy it). These changes occur underground and eventually the rock may be considered metamorphic.Igneous rocks that are exposed may be weathered and small particles deposited at riverbeds or ocean bottoms. After a long enough time, in the right conditions, these fragments bond together (much like concrete) to form sedimentary rock.
What three factors can change a sedimentary into a metamorphic rock?
heat,pressure,&chemically active fluids
What is the foliated metamorphic rock that forms when the sedimentary rock shale is subject to relatively low temperatures and pressures is?
(B)-slate
How do you make a sedimentary rock a metamorphic rock?
By applying increasing pressures or temperatures which cause mineralogical and structural changes to the rock.
Is anthracite coal a sedimentary rock?
No. Anthracite coal is a metamorphic rock.
Nonfoliated metamorphic rock definition?
Nonfoliated metamorphic rocks are formed around igneous intrusions where the temperatures are high but the pressures are relatively low and equal in all directions (confining pressure).
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 rock can be changed directly into with the application of heat and pressure?
Sedimentary rock can be changed into metamorphic rock through the application of heat and pressure. This process typically occurs deep within the Earth's crust, where existing rocks are subjected to high temperatures and pressures that cause them to recrystallize and form new minerals.
In order to form magma what must happen to sedimentary metamorphic or igneous rocks?
In order to form magma, sedimentary, metamorphic, or igneous rocks must be exposed to high temperatures and pressures deep within the Earth's crust. This process causes the rocks to partially melt, forming molten rock called magma.
How is metarmorphic rock made?
Metamorphic Rock is made from Igneous or sedimentary rock by experiencing extremely high pressures and temperatures. e.g. slate is formed from shail marble is formed from limestone
Is this true or false sedimentary rocks can be turned into metamorphic rocks when heat and pressure is applied?
True. Sedimentary rocks can undergo metamorphism when they are subjected to high temperatures and pressures deep within the Earth's crust. This process transforms the mineral composition and texture of the rock, creating metamorphic rocks.
What does sedimentary rock become when it is metamorphosed?
Sedimentary rock becomes metamorphic rock when subjected to high temperatures and pressures. This process causes the minerals within the sedimentary rock to recrystallize and reorganize, resulting in a new rock with different characteristics.
Which metamorphic rocks are most likely to have formed the highest temperatures and pressures?
Gneiss is a metamorphic rock that meets those criteria.
How do Sedimentary rocks change to Metamorphic?
Sedimentary rocks change to metamorphic rocks through the process of metamorphism, where heat and pressure alter the original sedimentary rock's mineralogy, texture, and structure. This process generally occurs deep within the Earth's crust where rocks are subjected to high temperatures and pressures, causing the recrystallization of minerals and the development of new textures.
