Contact

Dynamic

Regional
The mineralogy of a mteamorphic rock provides information on the
Degree or intensity of metamorphism
Metamorphic rocks form from:
Pre existing rocks
Metamorphism changes pre-existing rocks by changing their:
Texture

Composition
What types of transformations occur in a rock during metamorphism?
Mechanical transformation

Chemical transformation
Whats is the parent rock for marble?
Limestone
Marble is composed of what mineral?
Calcite
A metamorphic rock composed of alternating layers of ferromagnesian and non ferromagnesian minerals is called a:
Bneiss
Metamorphic changes occur while the rock is liquid or solid?
Solid
What type of metamorphism occurs when a limestone is intruded by a magma?
Contact
What type of metamorphism occurs in a fault zone?
Dynamic
What is the heat source for contact metamorphism?
Magma/rising magma
Fault breccia and fault gouge are evidence of:
Dynamic metamorphism
The parent rock of slate is:
Shale
What geologic process is responsible for regional metamorphism?
Mountain Building
Name one non-foliated metamorphic rock:
Marble
Name one foliated metamorphic rock:
Slate
What is contact metamorphism?
occurs because of an igneous intrusion
What is dynamic metamorphism?
Metamorphism along a fault
Evidence of a dynamic metamorphasm:
Fault gauge

Fault breccia
What theory can account for the forces that produce regional metamorphism?
Tectonism, constant moving and squeezing during mountain building.
The mineralogy of a metamorphic rock is a good guide to the:
Degree or intensity of metamorphism
The two textures of metamorphic rocks are:
Foliated

Non foliated
Foliated rocks have what type of appearance?
Refers to parallesm of the mineral grains. Rocks show a preffered orientation, the minerals are seperated into layers, lenses or bands
Do non-foliated rocks have a preferred orientation of the mineral grains?
No

Foliated
A rhyolite is what kind of rock?
Igneous
A sandstone iw what kind of rock?
Sedamentary
A gneiss is what kind of rock?
foliated
A basalt is what kind of rock?
Igneous
Marble is metamorphosed:
Limestone
Schists have what type of texture?
Glitters, spangly, sparkley
What is the parent rock for marble?
Limestone
What metamorphic rock has the ferromagnesian and non-ferromagnesian menerals separated into layers or lenses?
Foliated Rocks
What geologic process is responsible for the temperature and pressure required for regional metamorphism?
Mountain building

Tectonism
What is the mineralogy of a marble?
Calcite
What is the mineralogy of a limestone?
Calcite
In general, marble is------ grained, and limestone is-------grained.
Coarse and fine

Yes
Slate forms from the metamorphism of a?
Shale
In regards to the foliated metamorphic rocks, which rock represents the highest degree of metamorphism?
Gneiss
Can metamorphic rocks form from a cooling lave?
Forms in a solid state
