Engineering Geology Multiple Choice Questions on “Kinds of Metamorphism”.
1. The type of metamorphism in which heat factor has played an important role is ____________
a) Dynamic metamorphism
b) Thermal metamorphism
c) Thermodynamic metamorphism
d) Barometric metamorphism
Answer: b
Clarification: Thermal metamorphism is a general term including a variety of metamorphic processes in which the heat factor has played an important role.
2. Which type of metamorphism is common in rocks close to magmatic intrusions?
a) Contact metamorphism
b) Pyrometamorphism
c) Plutonic metamorphism
d) Dyke metamorphism
Answer: a
Clarification: Contact metamorphism is a common type of thermal observed in rocks existing close to the magmatic intrusions, injections and lava flows.
3. Type of metamorphism where part of country rock may get entrapped within magmatic body is ____________
a) Contact metamorphism
b) Pyrometamorphism
c) Plutonic metamorphism
d) Dyke metamorphism
Answer: b
Clarification: Pyrometamorphism is a type of thermal metamorphism in which case a part of country rock may actually get entrapped within a magmatic body. The effects result due to intense localized heating.
4. Metamorphism involving both temperature and load is ____________
a) Contact metamorphism
b) Pyrometamorphism
c) Plutonic metamorphism
d) Dyke metamorphism
Answer: c
Clarification: Plutonic metamorphism is a process of metamorphism that takes place due to equally important role of imposed loads and very high temperatures that become natural at those great depths.
5. Which kind of metamorphism is also called dislocation metamorphism?
a) Dynamic metamorphism
b) Thermal metamorphism
c) Thermodynamic metamorphism
d) Barometric metamorphism
Answer: a
Clarification: Dynamic metamorphism is also called clastic metamorphism, mechanical metamorphism or dislocation metamorphism and is brought about by conditions in which pressure factor plays a dominant role.
6. In which metamorphism there is almost no or little new mineral is formed?
a) Dynamic metamorphism
b) Thermal metamorphism
c) Thermodynamic metamorphism
d) Barometric metamorphism
Answer: a
Clarification: In the dynamic metamorphism, there is no or very little formation of new minerals. These are the original textures and structures of the rocks that are partially or totally obliterated.
7. Most prevalent kind of metamorphism is ____________
a) Dynamic metamorphism
b) Thermal metamorphism
c) Thermodynamic metamorphism
d) Barometric metamorphism
Answer: c
Clarification: Thermodynamic is also referred as regional metamorphism and may be considered as the most important as well as prevalent type of metamorphic processes.
8. Dynamothermal or thermodynamic metamorphism involves action of ____________
a) Temperature
b) Pressure
c) Fluids
d) Temperature, pressure and fluids
Answer: d
Clarification: Thermodynamic metamorphism involves the development of large-scale changes in the structural and chemical constitution of the pre-existing rocks under the combined action of pressure, temperature and fluids.
9. When the pressure acting on rock is of hydrostatic type then it is called ____________
a) Pressure metamorphism
b) Load metamorphism
c) Secondary metamorphism
d) Clastic metamorphism
Answer: b
Clarification: Sometimes the pressure is of the type of hydrostatic type such as load of the overlying rocks. The process is then called load metamorphism.
10. The kind metamorphism which occurs in the direction of mineralogical reconstitution is ____________
a) Dynamic metamorphism
b) Thermal metamorphism
c) Thermodynamic metamorphism
d) Barometric metamorphism
