- chemical sedimentary rock
- sedimentary rock that forms when minerals precipitate from a solutio n or settle from a suspention
- organic sedimentary rock
- sedimentary rock that form from the remains of plants or animals
- mafic
- describes magma or igneouse rock that is rich in magnesium and iron and that is generally dark in color
- Brwne's reaction series
- the simplifies pattern that illustrates the order in which minerals crystallize from cooling magma according to their chemical composition and melting point
- cementation
- thge process in which minerals precipitate into pore spaces between sediment grains and bind sediments together to form rock
- metamorphism
- the process in which one type of rock changes into metamorphic rock because of chemical processes or changes in temerature and pressure
- igneous rock
- rock that forms when magma cools and solidifies
- Rock cycle
- the series of processes in which rock forms, change from one type to another, is destroyed,and forms again by geological processes
- regional metamorphism
- a change in the texyure, structure, or chemical composistion of a rock due to changes in the temperature and pressure over a large area, generally as a result of tectonic forces
- clastic sedimentary rock
- sedimentary rock that form when fragments of preefixising rocks compacted or cemented together
- felsic
- describes magma or igneouse 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 decreased by the weight of overlying sediments as a result of burial beneath other sediments
- intrusive igneous rock
- rock formed from the cooling and solitification of magma beneath Earth's surface
- contact metamorphism
- a change in the texyure, structure, or chemical composistion of a rock due to contact with magma
- foliated
- the metamorphic rock mineral grains are arranged in planes or bands
- extrusive igneouse rock
- rock that forms from the cooling and solitification of lava at Earth's surface
- nonfoliated
- the metamorphic rock mineral grains are not arranged in planes or bands
