- Cementation
- The process in which minerals precipitaye grains and bind sediments together to form rock.
- Mafic
- Describes magma or igneous rock that is rich in magnesium and iron and that is generally dark in color.
- Clastic sedintary rock
- Sedimentary rock that forms when fragments of preexisting rocks are compacted or cemented together.
- Extrusive igneous rock
- Rock that forms from the cooling and solidification of lava at Earth's surface
- Chmical sedimentary rock
- Sedimentary rock that forms when minerals precipitate from a solution or settle from a suspension.
- Felsic
- Describes magma or igneous rock that is rich in feldspars and silica and that is generally light in color.
- Compaction
- The process in which the volume and porosity of a sediment is dercreased by the weight of overlying sedments as a result of burial beneath other sediments.
- Intrusive igneous rock
- Rock formed from the cooling and solidification of magma beneath Earth's surface.
- Igneous rock
- Rock that forms when magma cools and solidifies.
- Contact metamorphism
- A chnage in the texture, structure, or chemical compostion of a rock due to contact with magma.
- Regional metamorphism
- A change in the texture, structure, or chemical compostion of a rock due to changes in temperature and pressure over a large area, generally as a result of tectonic forces.
- Metamorphism
- The process in which one type of rock changes into metamorpic rock because of chemical processes or changes in temperature and pressure.
- Rock Cycle
- The series of processes in which rock forms,changes from one type to another,is destroyed,and forms again by geological processes.
- Nonfoliated
- The metamorphic rock texture in which mineral grains are not arranged in planes or bands.
- Foliation
- The metamorphic rock texture in which mineral grains are arranged in planes or bands.
- Bowen's reaction series
- The simplified pattern that illustrates the order in which minerals crystallize from cooling magma according to their chemical composition and melting point.
- Organic sedintary rock
- Sedimentary rock that forms from the remains of plants or animals.
