(I think)
Metamorphic rock forms at depths between 2 and 70 miles, shallower at areas of tectonic compression or shearing, deeper from overburden pressure and heat only.
Forms when existing rocks are changed by heat and pressure.
Quartzite is a metamorphic rock formed from sandstone.
Marble is the metamorphic rock formed from limestone. =)
