When a tectonic plate in a subduction zone, goes underneath another tectonic plate, the magma in the Earth's core causes the plate to break up and melt. This melted rock becomes magma, and when it pushes through the Earth's crust to create a volcanic eruption, the magma cools and becomes rock. This rock is Metamorphic rock.
Marble is the metamorphic rock formed from limestone. =)
Anthracite, which is metamorphosed bituminous coal.
Mica is formed by chemicals combining their industrial forces with fresh water and turning into thin breakable sheet rock.
The most common metamorphic rock associated with the regional, contact, or depth of burial metamorphosis of sandstone is quartzite.
No, it is a metamorphic rock. (metamorphosed limestone)
Marble is formed when limestone is metamorphosed.

Metamorphic rock can form from igneous and sedimentary rock. It can also form from previously metamorphosed rock into a higher grade metamorphic rock.
Sandstone can be metamorphosed into quartzite. Heat and pressure bake the sandstone and it becomes extremely hard.
Shale is a sedimentary rock that can be metamorphosed into slate by "increased pressure" and heating.
Pilot Mountain in northwest North Carolina is composed mainly of the metamorphic rock quartzite which formed when the original sandstone was metamorphosed during uplift that formed the mountain.
