Metamorphic Rock Notes Flashcards
Where they form:
Deep within the earth
Does this rock melt?
Never
Classified Upon:
The basis of formation
Types of Metamorphism:
Regional
Contact
Regional:
Form by heat and/or pressure, during mountain building or continental collisions
Contact:
Form by direct contact with molten rock
Parts of regional metamorphism:
Foliations
Banding
Distortion
No fossils
Foliations:
Alignment or segregation of minerals in a metamorphic rock, producing a layered apperance
Banding:
Type layering or foliation found in some metamorphic rocks, rocks that are caused by movement or growth of minerals into homogenous
Distortion:
Warping or bending of some types of metamorphic rocks that occur with intense pressure
Would you find fossils in this type of rock?
No
Formed By:
Sedimentary, igneous or metamorphic rocks undergo intense heat and/or pressure
