What is the texture of Dunite?
The texture of dunite is very rough and it also has a very crystal like feel
Is dunite intrusive or extrusive?
extrusive
Is dunite an intrusive or extrusive igneous rock?
intrusive
Why dunite has no volcanic equivalent?
Dunite is composed predominantly of olivine. A volcanic rock of dunite composition would need to form from a lava/magma of dunnite composition. A magma of dunite i.e. olivine composition would never be produced from melting of mantle or crustal rocks because olivine melts/crystallises at higher temperatures than most other minerals. Therefore, melting any rock other than dunite itself would produce a magma with a composition less Fe-Mg-rich than dunnite. Dunite forms in 2 ways: When olivine is concentrated by accumulation at the base of a magma chamber (cumulate layaered gabbro); and by chemical reaction between an exsolved basaltic melt and residual peridotite in the lithospheric mantle. Pyroxene in the mantle dissolves and olivine is left behind as a residual material.
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.
Is dunite or olivine a common rock?
Dunite is not a common rock but olivine is.
What is the texture of Dunite?
The texture of dunite is very rough and it also has a very crystal like feel
Is dunite intrusive or extrusive?
extrusive
What is the color of dunite?
Light green.
Which rocks are metamorphic rocks?
Marble (metamorphosed limestone) Slate (metamorphosed shale) Gneiss (metamorphosed granite)
What is a metamorphosed coal?
Metamorphosed coal is called Anthracite.
Is dunite a rock or mineral?
Duntie is a rock
How does Dunite form?
through heat lol
Does Dunite cool quickly or slowly?
slowly
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.
What rock is formed when limestone is metamorphosed?
Marble is formed when limestone is metamorphosed. This process occurs when the mineral calcite in limestone recrystallizes due to heat and pressure, resulting in a denser, harder rock with a crystalline structure.
What color is dunite?
Gray to rely light green.
