Is nickel metamorphic sedimentary or igneous rock?

Nickel itself is not a type of rock; rather, it is a metal that can be found in various geological contexts. Nickel is often associated with igneous rocks, particularly in the form of sulfide deposits, which can form from magmatic processes. It can also be found in some metamorphic rocks, but it is not typically classified as a sedimentary rock. Overall, nickel is primarily linked to igneous processes in the Earth's crust.
