It's important to understand that you cannot have a rock that is both igneous and sedimentary. Here's why:

* Igneous Rocks: Formed from the cooling and solidification of magma or lava.

* Sedimentary Rocks: Formed from the accumulation and cementation of sediments (fragments of other rocks, minerals, or organic matter).

Metamorphic rocks are formed when existing rocks (igneous, sedimentary, or even other metamorphic rocks) are transformed by heat, pressure, or chemically active fluids.

Here's how you can think about metamorphic rocks in relation to the other types:

* Metamorphic Igneous Rocks: An igneous rock like granite can be metamorphosed into a metamorphic rock like gneiss.

* Metamorphic Sedimentary Rocks: A sedimentary rock like limestone can be metamorphosed into marble.

Examples of Metamorphic Rocks:

* Gneiss: Formed from the metamorphism of granite (igneous)

* Marble: Formed from the metamorphism of limestone (sedimentary)

* Schist: Formed from the metamorphism of shale (sedimentary)

* Quartzite: Formed from the metamorphism of sandstone (sedimentary)
