Name the rock: Contact metamorphism of various rocks - due to extreme heat from nearby lava
Hornfels
What is Foliation?
Minerals become aligned
A metamorphic rock can show a structure of distorted layers. What causes this?
Extreme Pressure
What is the Parent rock of Marble?
Limestone or Dolostone
Name the rock: Coarse-grained, contains distorted pebbles
Metaconglomerate
Name the rock: Has Banding
Gneiss
Forms from the metamorphism of Limestone or Dolostone.
Marble
Fine to medium grain size, contains clay minerals but never pyroxene
Phyllite
What is the Metamorphic rock Mantra?
Intergrown crystals in an organized pattern
Name the rock: Contains only Mica
Slate
What is the parent rock of Quartzite?
Sandstone
Name the rock: Parent rock is Dolostone
Marble
What are the 2 processes that form Metamorphic rocks?
Heat and Pressure
Which rock exhibits platy mica crystals due to Regional metamorphism?
Schist
Which sedimentary rock is most likely to be changed to SLATE during regional metamorphism?
Shale
Name the rock: Foliated, High-grade metamorphism, contains pyroxene and quartz
Gneiss
What is a difference in texture between the rocks SCHIST and QUARTZITE?
Schist is FOLIATED, Quartzite is not.
This rock forms from Contact Metamorphism of Shale.
