Sedimentary Rocks
|
-Any type of rock can form the basis of sedimentary
-(uplift and exposure) Weathering, transportation,Deposition -Sediments -> lithification (compaction and cementation) |
|
|
Metamorphic Rocks
|
-> Can be formed from both types of igneous rocks (extrusive and intrusive) and sedimentary rocks.
-> Metamorphism occurs from other rock types to produce this rock. |
|
|
Igneous Rocks (Extrusive/Volcanic)
|
-> Formed from metamorphic rocks
-> Rock melts through melt, going through magma and then CONSOLIDATES to be extruded volcanically. |
|
|
Igneous Rocks (Intrusive/Plutonic)
|
-> Formed from metamorphic rocks
-> Rock melts through magma and CRYSTALLIZES to be intrusive igneous rock. |
|
|
Regional metamorphism
|
Occurs over a LARGE AREA and is caused by INCREASED PRESSURE and TEMPERATURE as a result of burial and mountain building forces
|
|
|
Contact metamorphism
|
Occurs in a SMALL LIMITED AREA and is caused by the RELEASE OF HEAT following INTRUSION of an IGNEOUS body.
