Agents of Metamorphism
This agent can result from magma or geothermal gradient
What is heat?
This type of metamorphism is only found in fault zones
What is dynamic metamorphism?
This is the term used to describe minerals that form at specific temperatures and pressures during metamorphism
What is an index mineral?
A metamorphic rock that has a repetitive planar feature throughout the rock is known as this
Transform boundaries will mostly have this agent at work
What is differential stress?
This agent of metamorphism results from rocks being buried deep within the earth
What is lithostatic pressure?
This type of metamorphism is found around large plutonic bodies
What is contact metamorphism?
A rock that undergoes high grade metamorphism will experience this
What is high temps and high pressures?
Marble and quartzite are examples of this type of metamorphic texture
What is non-foliated?
Convergent boundaries will have these agents at work
What are heat, lithostatic pressure, differential stress and hydrothermal fluids
This agent of metamorphism results from the combination of heat and water
What is hydrothermal fluid
This is the type of metamorphism found along convergent boundaries
What is regional metamorphism?
If a rock were to experience temps and pressures greater than those found during high grade metamorphism, it would become this
What is magma (or igneous rock)
Rocks that experience compression during metamorphism will have elongated minerals lining up in this orientation relative to the stress direction
What is perpendicular?
Divergent boundaries will commonly have these agents at work
What are heat and hydrothermal fluids?
This agent of metamorphism results from the application of tension, compression or shear stresses
What is differential stress?
True or False - only one type of metamorphism can be found in an area
What is false?
Rocks that experience shear stress will have elongated minerals line up in this orientation relative to the stress direction
What is parallel?
This plate boundary is responsible for the greatest volume of metamorphic rock on earth
What is convergent?
