n: a type of metamorphism that occurs when an intruded body of molten igneous rock changes the rocks immediately around it, primarily ny heating and by chemical alteration.

n: the process in which rock may be changed by heat and pressure into different forms.

n: a compact granular rock composed of quartz and derived from sandstone by metamorphism.

n: a type of metamorphism that occurs in bodies of rock that have been deeply buried or greatly defonned by tectonic changes.

n: the possible sequences of events, all interrelated, by which rocks may be formed, changed, destroyed. or transformed into other types of rock. The events include formation from magma, erosion, sedimentation, and metamorphism.

n: a coarse-grained, foliated metamorphic rock that splits easily into layers. It is formed when shale under deep burial becomes slate and then, with more intense metamorphism, becomes schist.

a crystalline metamorphic rock that can be split into think layers because of the bedded mineral arrangements.
