- organic sedeimentary rock
- sedimentary rock that forms from the remains of plants or animals
- chemical sedimentary rock
- sedimentary rock that forms when minerals precipitate from a solution or settle from a suspension
- contact metamorphism
- a change in the texture, structure or chemical composition of a rock due to contact with magma
- mafic
- describes magma or igneous rock that is rich in magnesium and iron and that is generally dark in color.
- intrusive igneous rock
- rock formed from the cooling and solidification of magma beneath earth's surface.
- compaction
- the process in which the volume and porosity of a sediment is decreaded by the weight of overlying sediment as a result of burial beneath other sediments.
- nonfoliated
- the metamorphic rock texture in which mineral grains are not arranged in places or bands
- extrusive igneous rock
- rock that forms from the cooling and solidification of lava at earth's surface.
- foliation
- the metamorphic rock texture in which mineral grains are arranged in planes or bands
- metamorphism
- the process in ehoch one type of rock changes into meramorphic rock because of chemical processes or changes in temperayure and pressure
- regional metamorpism
- a change in the texture, structure or chemical composition of a rock due to change in temperature and pressure over a large area, generally as a result of tectonic forces
- rock cycle
- the series of processes in which forms, change from one type to another, is is destriyed, and forms again by goelogical processes.
- Cementation
- the process in which minerals precipatate into pore spaces between sediment grain and bind sediment together to form rock
- bowen's reaction series
- the simplified pattern that illustrates the order in which minerals crystallize from cooling magma according to their chemmical composition and melting point
- felsic
- describes magma or igneous rock that is rich in feldspars and silica and that is generally light in color.
- igneuos rock
- rock that forms when magma cools and solidifies.
- clasic sedimenrary rock
- sedimentary rock that forms when fragments of preexising rocks are compacted or cemented together
