3. Metamorphic Rocks Quick Notes
Metamorphic Rock ~ type of rock that forms from an existing rock that is changed by extreme heat and/or pressure
The pressure and heat responsible for metamorphic rocks come from:
• The internal heat of the earth
• Intruding magma within the earth
• The weight of overlying rock
Typically occurs at depths between 10 to 30 km where pressure is 6 times greater and temperature is 800 °C greater than at the surface of the earth! Metamorphic rocks are denser and harder than igneous and sedimentary rocks.
There are two (2) groups of metamorphic rocks based on their textures:
Foliated Metamorphic Rocks ~ metamorphic rocks with visible layers or elongated grains of minerals
• The minerals in these rocks have been squeezed into parallel layers by intense pressure
2. Non-foliated Metamorphic Rocks ~ rocks that do not have distinct layers or bands
• The majority of these rocks are formed by extreme heat
Examples of Metamorphism:
• Granite turns into Gneiss
• Sandstone turns into Quartzite
• Limestone turns into Marble
• Shale turns into Slate
