conditions where meta takes place |
high pressure
high heat
rapid/slow cooling |
contact meta |
metamorphism by heat around a magma intrusion |
Regional Metamorphism |
metamorphism associated with mountain building and subduction zones.
produces the most meta rocks |
burial meta |
sediments buried and exposed to elevated pressure and temp |
Low grade |
fined grained |
high grade |
coarse grained |
can new minerals be formed during metamorphism? |
yes |
Metamorphic rocks can form from other metamorphic rocks? |
yes |
A metamorphic rock's texture and composition reflect the degree of metamorphism it has undergone. |
true |
foliation tends to occur in an orientation that is.....to the direction of the applied stress |
parallel |
how are non foliated metamorphic rocks formed |
the temperatures are high but the pressures are relatively low |
what type of metamorphism produces most metamorphic rocks? |
regional met |
hydrothermal |
circulation of hot water through rocks |
