Question 1

low-grade qualities

Answer 1

low temp/pressure, less than 400 degrees / MPA

Question 1

high-grade qualities

Answer 1

high temp/pressure, more than 400 degrees / MPA

Question 2

foliated qualities on banding, stress, squishing

Answer 2

banded, layered, different stress, arranged, squishing together

Question 3

non foliated qualities on banding, stress, squishing

Answer 3

massive, no banding, uniform stress, no squishing

Question 4

protolith definition

Answer 4

parent rock

Question 5

what happens when you increase temp on grain size and water content

Answer 5

increase grain size, decrease water content, grow new minerals

Question 6

what happens when you increase temp a lot

Answer 6

melt at 700 degrees, create magnitude

Question 7

what happens when you increase pressure (density, porosity)

Answer 7

increase density, deform rock, decrease porosity

Question 8

what is contact metamorphism on pressure, heat, deformation

Answer 8

low pressure, high heat, no deformation, “baked zone”

Question 9

what is hydrothermal metamorphismon pressure, heat, deformation

Answer 9

low pressure, high heat, chem charge parent rock, low from hot water precipitation

Question 10

what is regional metamorphism

Answer 10

both temp and pressure increase

Question 11

what is burial metamorphism

Answer 11

bury very deep, increase temp/pressure
