ANSWER
Calcite is really not a rock it is a mineral therefore it can not really be metamorphic , sedimentary , or igneous. But it is usually associated in materials of sediment so most likely it is sedimentary. If you would have to pick one. SEDIMENTARY
asial sedimentary igneous metamorphic
If any kind of rock-igneous or sedimentary- is far enough beneath the surface, the pressure can change it into a metamorphic rock. Also heat - the effects differ. It doesn't have to be ever so deeply buried, geologically, since metamorphism is usually a orogenic process in the affected sedimentary rock.
No matter what kinds of rocks they are they can be changed into any other kind of rock. Sedimentary rocks and igneous rocks can become metamorphic rocks with either contact or regional metamorphism. This means that either the rocks have been in contact with or close to high heat and high pressure that changes the rock.
Sedimentary rocks can be made from any kind of material, from other rocks to shells to plant material. Basically, any rock, from metamorphic to igneous and even to sedimentary, can be weathered and eroded. These particles and grains can be carried great distances by wind, water, ice, etc. before they are deposited and lithified (cemented) back together to form sedimentary rocks.
As in what process causes this? if so it is usually under heat and pressure. Depending on what kind of rick it is depends on the resultant metamorphic rock e.g Shale-->Slate etc
Igneous, Sedimentary, and Metamorphic
---- ====== ====== Is it a igneous , marble , metamorphic , or sedimentary
pegmatite rock is a igneous rock
Igneous Rock
Sedimentary or metamorphic.
Either metamorphic or igneous.
In Igneous, Metamorphic, and Sedimentary rocks.
All rocks are solid. Igneous, metamorphic, or sedimentary.
All sedimentary and igneous rocks
Any rock, be it igneous, sedimentary or metamorphic, can be changed into a metamorphic rock through increased pressure and/or temperature.
There are three kinds of rock in the world: igneous, metamorphic and sedimentary.
Metamorphic rocks are rocks that have "morphed" into another kind of rock. These rocks were once igneous or sedimentary rocks.
