Metamorphic Rocks
2
Metamorphic Rock Features
Foliation, the appearance of banding such as gneissic banding. Nonfoliated rocks are a single solid color.
Rock Cleavage occurs when rocks tend to split or break along a single planar fabric caused by the intense pressure of metamorphism
Lineation occurs when minerals within the rock become aligned in the same direction.
3
Multiple Choice
What metamorphic feature is being illustrated in this sample of schist.
rock cleavage
foliation
lineation
4
Multiple Choice
This sample of marble is illustration foliation.
True
False
5
Multiple Choice
Which metamorphic feature is being illustrated by this sample of slate?
rock cleavage
foliation
lineation
6
Metamorphism of Shale
Under low-grade metamorphism will become slate
Under medium-grade will become phyllite or schist
Under high-grade will become gneiss
Under High-T/Low-P of contact metamorphism will become Hornfels
7
Nonfoliated Metamorphic Rocks
Sandstone will become Quartzite, shown here
Limestone will become Marble
High-grade metamorphism will create larger crystals giving these a coarse texture.
8
Multiple Choice
Which of the metamorphic rocks is not created by the metamorphism of shale?
schist
marble
gneiss
slate
9
Metamorphism of Igneous Rocks
Basalt will become greenstone (shown with veins) or greenschist
Rhyolite becomes metarhyolite and then schist
Plutonic granite becomes deformed granite or gneiss
10
Multiple Choice
Which of these metamorphic rocks is not made from an igneous parent rock?
greenstone
schist
gneiss
quartite
11
Major causes of metamorphism
Contact metamorphism, when rock comes into close contact with a heat source such like a magma chamber
Regional metamorphism, when stress from tectonic collisions creates large scale metamorphism
12
Multiple Choice
The type of metamorphism shown here that is caused by the collision of two continental plates is
contact metamorphism
regional metamorphism
13
Multiple Choice
