What is foliated in a metamorphic rock quizlet?
foliated metamorphic rock that has a banded appearance and is made up of granular mineral grains. It typically contains abundant quartz or feldspar minerals. a non-foliated metamorphic rock that is produced from either regional or contact metamorphism of limestone.
What is a metamorphic foliated rock?
Foliated metamorphic rocks have a layered or banded appearance that is produced by exposure to heat and directed pressure. Examples of foliated rocks include: gneiss, phyllite, schist, and slate. Non-foliated metamorphic rocks do not have a layered or banded appearance.
How do foliated metamorphic rocks form quizlet?
How do foliated metamorphic rocks form? Foliation forms when pressure squeezes the flat or elongate minerals within a rock so they become aligned. These rocks develop a platy or sheet-like structure that reflects the direction that pressure was applied in.
What are the characteristics of a foliated metamorphic rock quizlet?
Foliated metamorphic rocks exhibit layers or stripes caused by the elongation and alignment of minerals in the rock as it undergoes metamorphism. In contrast, nonfoliated metamorphic rocks do not contain minerals that align during metamorphism and do not appear layered.
What does foliated mean quizlet?
What does foliated mean? Foliated means that the minerals in a metamorphic rock are aligned in sheets or bands (like stripes if colors contrast)
What metamorphic rocks are non-foliated?
Types of non-foliated metamorphic rocks include marble, quartzite and hornfels.
What is foliated and non foliated metamorphic rocks?
Foliated metamorphic rocks such as gneiss, phyllite, schist and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure. Non-foliated metamorphic rocks such as hornfels, marble, quartzite and novaculite do not have a layered or banded appearance.
How does a metamorphic rock form quizlet?
Metamorphic rocks are formed by intense heat, intense pressure, or by the action of watery hot fluids (metamorphism). Any of the rock types in the rock cycle can be metamorphosed, or changed into a metamorphic rock (metamorphic rock can be metamorphosed again).
What are metamorphic rocks made from quizlet?
A metamorphic rock is a rock whose original form and/or mineralogy has been changed, through pressure and/or temperature changes. Metamorphism generally occurs below the earth’s surface. They are all derived from preexisting rock, also known as the parent rock or protolith.
What causes foliated metamorphic textures to form?
Foliated Metamorphic Rocks: Foliation forms when pressure squeezes the flat or elongate minerals within a rock so they become aligned. These rocks develop a platy or sheet-like structure that reflects the direction that pressure was applied.
