- Bowen's reaction series
- the simplified pattern that illustrates the order in which mireals crystallize from cooling magma according to their chemical composition and melting point
- organic sedimantary rock
- sedimentary rock that forms from the remains of plants or animals
- compaction
- the processes in which the volume and porosity of a sediment is decreased by the weight of overlying sediments as a result of burial beneath other sediments
- cemetation
- the process in which minerals precipatate into pore spaces between sediment grains and bind sediments together to form rock
- contact metamorphism
- a change in the texture, structure, or chemical composition of a rock due to contact with magma
- foliatoin
- the metamorphic rock texture in which mineral grains are arrangedin planes or bands
- igneous rock
- rock that forms when magma cools and solidifies
- nonfoliated
- the metamorphic rock texture in which mineral grains are not arranged in planes or bands
- metamorphism
- the processes in which one type of rock changes into metamorphic rock because of chemical processes or changes in temperature and pressure
- extrusive igneous rock
- rock that forms from the cooling and solidification of lava at Earth's surface
- rock cycle
- the series of processes in which rock forms, changes from one type to another, is destroyed, and forms again by geological process.
- mafic
- describes magma or igneous rock that is rich in magnesium and iron and that is generally dark in color
- reginal metamorphism
- a change in the texture, structure, or chemical composition of a rock due to changes in temperature and pressure over a large area
- felsic
- describes magma or igneous rock that is rich in feldspars and silica and that is generally light in color
- clasitc sedimentary rock
- sedimentary rock that forms when fragments of preexisting rocks are compacted or cemeted together
- intrusive igneous rock
- rock formed from the cooling and solidification of magma beneath Earth's surface
- chemical sedimentary rock
- sedimentary rock that forms when minerals precipitate from a solutionor settle from a suspension
