pegmatite rock is a igneous rock
Sedimentary rocks: Rock formed when chemical reactions cement sediments (small, solid fragments of rocks and other materials) together, hardening them. Igneous rocks: Rock that forms from molten rock (hot magma thats cools and hardens). Metamorphic rocks: Igneous/sedimentary rock that has been changed into a new kind of rock as a result of great pressure and temperature.
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.
A sedimentary rock can change from that to a metamorphic rock then into an Igneous rock. e.g. Mudstone (sedimentary) is in the Zone of Diagenesis, when it is subjected to regional metamorphism (in mountain belts) it changes from a mudstone to a slate (low grade) then to a Phillite (medium grade) then a Schist (medium) then a gneiss (high grade) then into a Milonite (high grade) then once past the line of partial melting it has so much pressure and so much temperature that it turns into an Igneos rock. This is the basic explanation of this. If you want to know more, just ask me.Sedimentary rocks are changed into metamorphic by being buried deep enough that the heat and pressure alter their text, mineralogy, or other characteristics.
Igneous rocks and most metamorphic rocks, of an igneous origin.
If you want just one I would say sedimentary, but I'm not sure. According to a page/article, "most of the rocks in westchester probably began as a mixture of sedimentary and igneous rocks", so its definietly not metamorphic.

Igneous, Sedimentary, and Metamorphic
Sedimentary or metamorphic.
Either metamorphic or igneous.
Igneous Rock
In Igneous, Metamorphic, and Sedimentary rocks.
All rocks are solid. Igneous, metamorphic, or sedimentary.
All sedimentary and igneous rocks
ANSWERCalcite 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
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.
