Basics--Metamorphic Rocks Table

The higher the temperature of metamorphism, the higher the metamorphic grade. Most metamorphic rocks form during regional metamorphism, where whole sectors of the crust are pressurized and heated, forcing large volumes of rock to recrystallize into new minerals that are stable under the new conditions.

How Does Marble Form? Reference

Marble is a soft metamorphic rock that forms at the edges of tectonic plates, where limestone is exposed to regional metamorphism. The heat and pressure of the metamorphic zone force calcite inside the limestone to recrystallize and merge into the classic marble consistency. Marble begins as limestone near the edges of tectonic plates.
