Metamorphism

Question 1

process of changing the
characteristics of a rock as a result
of changes in temperature,
pressure, or reactions with hot
fluids.

Answer 1

Metamorphism

Question 2

Slate is a product of metamorphism from
a protolith which is shale.

Question 3

is a pre-existing rock
that undergoes metamorphism.

Answer 3

protolith

Question 4

This is the process where there is a
growth in size of the mineral grains
of pre-existing materials.

This is the most common process
involved in metamorphism.

limestone to marble; clay into
muscovite mica.

Answer 4

Recrystallization

Question 5

It is the formation of new
minerals from the pre-existing
minerals due to heat.

Phyllite is a mica-rich
mineral rock. When clay
undergoes neocrystallization, it
forms mica.

Answer 5

Neocrystallization

Question 6

It refers to the change in mineral structure but with the
same chemical formula (example: andalusite to kyanite).

Answer 6

Phase Change

Question 7

Minerals with the same chemical formula but different
mineral structure are called

Answer 7

polymorphs

Question 8

It takes place when
minerals are dissolved in
areas with high pressure
and recrystallize in other
areas with low pressure.

Answer 8

Pressure Solution

Question 9

It occurs when
mineral grains soften
and deform at high
temperatures.

Answer 9

Plastic deformation

Question 10

recrystallization, neocrystallization, phase
change, pressure solution, and plastic deformation.
