Shale is a sedimentary rock that can be metamorphosed into slate by what?
Shale can be metamorphosed into slate through the process of low-grade regional metamorphism, which involves heat and pressure causing the minerals within the shale to recrystallize into a fine-grained, foliated structure characteristic of slate.
Does sedimentary rock become metamorphic rock after millions of years?
Yes, sedimentary rock can undergo metamorphism to become metamorphic rock over millions of years due to high temperatures and pressures deep within the Earth's crust. This process can cause the minerals in the sedimentary rock to recrystallize and form new minerals, resulting in a metamorphic rock with a different texture and mineral composition.
What are the common minerals called?
The Solvent
What b do minerals sometimes form in metamorphic rock?
Minerals in metamorphic rocks can form due to changes in temperature and pressure, which cause existing minerals to recrystallize or new minerals to grow. The specific minerals formed depend on the original composition of the rock and the conditions under which the metamorphic process occurred.
What is metamorphosed basalt?
Metamorphism is when a rock of any particular composition get heated and put under pressure such that it partially melts and the chemical elements that make up the minerals rearrange to form new, usually high temperature and pressure versions of the original minerals since the composition is the same. The pressure is provided usually over a long period of burial or tectonic movement and the heat is either on a regional or local scale (contact metamorphism) where the rocks being metamorphosed have a magma intruded next to them. Basalt is an igneous rock (erupted from volcano) and is fine grained, ie. they cool quickly. Depending on the particular temperature and pressure it undergoes its minerals will change into particular other minerals. Metamorphic rocks of particular composition have been put into what are called 'facies'. Read more at: http://en.wikipedia.org/wiki/Basalt#Metamorphism and http://en.wikipedia.org/wiki/Blueschist for a decent start. Metamorphosed basalts are also important hosts for a variety of hydrothermal ore deposits, including gold deposits, copper deposits, volcanogenic massive sulfide ore deposits and a few others. (Wiki)
What is amphibolite made of?
Amphibolite is a type of metamorphosed mafic igneous rock. It is composed largely of minerals such as hornblende and plagioclase.
What is the hardness of a metamorphic rock?
Depends on which one. Diamond is a metamorphosed coal/carbon that is the hardest natural substance known. Marble is metamorphosed limestone that is much softer. It's safe to say that all metamorphosed rocks are harder than they were in their pre-metamorphosed form.
How can rock minerals form?
Rock minerals form from lava, magma or solutions.
What type of sedimentary rock is typically metamorphosed to form slates or phyllites?
shale or mudstone
What type of rock can only be formed from sedimentary rock or igneous rock?
Metamorphic rock can form from igneous and sedimentary rock. It can also form from previously metamorphosed rock into a higher grade metamorphic rock.
Shale is a sedimentary rock that can be metamorphosed into slate by what?
Shale can be metamorphosed into slate through the process of low-grade regional metamorphism, which involves heat and pressure causing the minerals within the shale to recrystallize into a fine-grained, foliated structure characteristic of slate.
What is the metamorphosed form of dolomite?
The metamorphosed form of dolomite is called marble. Dolomite is a sedimentary rock primarily composed of the mineral dolomite, while marble is a metamorphic rock that forms from the recrystallization of limestone or dolomite under high heat and pressure.
What is the hardness of the Metamorphic rock?
Depends on which one. Diamond is a metamorphosed coal/carbon that is the hardest natural substance known. Marble is metamorphosed limestone that is much softer. It's safe to say that all metamorphosed rocks are harder than they were in their pre-metamorphosed form.
What happens to the minerals when a rock is metamorphosed?
In metamorphic rocks, minerals occur in joints, faultsor crevices.. they are formed when minerals in their molten, liquid or gaseous form move towards the earth's surface. then they cool and solidify. and in dis way they are formed.
What are 3 specific types of metamorphic rocks and what was their parent rock?
Slate--metamorphosed shale or mudstone.Phyllite--metamorphosed slate.Quartzite--metamorphosed sandstone.
Name one metamorphosed rock from a sedimentary rock?
Quartzite
What are minerals that form in a rock forming a fossil?
Replacement minerals.
