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.
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).
Are fossils the most characteristic that is common to metamorphic rocks?
No, metamorphic rock is not conducive to preserving fossils because of the high pressures and temperatures it has been subjected to that destroys organic matter. Most fossils are found in sedimentary rock.
How can mudstone be changed into a metamorphic rock?
It can be buried, and huge pressures and temperatures can change them into metamorphic rocks.
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
Why is coal both a sedimentary and metamorphic rock?
Most coal is sedimentary, but anthracite is metamorphosed bituminous coal, a result of mountain building pressures on sedimentary coal.
Which metamorphic rocks are most likely to have formed the highest temperatures and pressures?
Gneiss is a metamorphic rock that meets those criteria.
What rock family forms magma if the temperatures and pressures are great enough to melt rock?
metamorphic
Which kind metamorphic rock most likely form in the high temperatures and pressures?
At the highest temperatures and pressures, high-grade metamorphism occurs forming high-grade metamorphic rocks. The main example of this is gneiss.
Is limestone rock hard or soft?
Generally speaking, when a geologist talks of "soft rocks" and "hard rocks" what he or she means is "sedimentary rocks" or "igneous and metamorphic rocks". Limestone is a sedimentary rock, and compared to most other rocks, is relatively soft. lol Different limestones have different hardnesses. Most "marbles" are actually hard limestones, because they have not experienced the high pressures and temperatures required for metamorphism.
What rocks are formed from high temperature and pressures?
Igneous, metamorphic, and sedimentary rocks can be changed by high temperatures and pressure, and the resultant rock is called metamorphic, because its form has been changed.
