3 Main Rock Types

Metamorphic rocks form from HEAT&PRESSURE

Contact MetamorphismDeep underground, zones of metamorphism form around the hot magma of batholiths.L.Gardiner/Windows Original

Regional MetamorphismTectonic forces smash continents together. The rocks get heated and become semi-molten. The added pressure causes the mineral to separate into bands and sometime to even flow before cooling again!

Common Metamorphic RocksParent Rock Metamorphic Rock

Granite Gneiss

Shale Slate

Sandstone Quartzite
