Metamorphic rocks are any rock type that has been altered by heat, pressure, and/or the chemical action of fluids and gases. Metamorphic rocks are classified by their structure and their dominant minerals. Metamorphic rock structure is either foliated (has a definite planar structure) or nonfoliated (massive, without structure).

The metamorphic cycle is the third largest cycle in mineral and rock formation. Metamorphism is the alteration of mineral paragenesis (the order of formation) after their deposition, by external action such as contact with magmetic rocks, regional changes in the pressure and temperature (e.g. contact metamorphosed limestones, crystalline schists, etc.).Tiger's Eye is a metamorphic rock with a golden-red to brown color. It's at faults where rocks will undergo regional metamorphism. For example, gneiss is a metamorphic that forms due to intense pressure. Gneiss is known for having bands where all the layers are squeezed.Study with Quizlet and memorize flashcards containing terms like Slate - Foliated (Black w/ grey circles) - Microscopic crystals - Dark colored - Similar to chalkboards (writable) - Protolith: Mudstone (Quartz) or Shale (Micas) - Dynamothermal Metamorphism (Differential P), Phyllite - Foliated - Microscopic crystals - Slightly shiny luster - Grey colored - Breaks into sheets - Protolith ...Metamorphic rocks are any rock type that has been altered by heat, pressure, and/or the chemical action of fluids and gases.
