What does metamorphism of sandstone produce?
1. Metamorphism of quartz-rich sandstone produces quartzite (Fig. 8.9), a very hard, nonfoliated metamorphic rock consisting almost entirely of silica.
What is metamorphosed sandstone called?
Quartzite is metamorphosed sandstone (Figure 7.11). It is dominated by quartz, and in many cases, the original quartz grains of the sandstone are welded together with additional silica.
What are the words associated with metamorphism?
Synonyms of metamorphosed
- alchemized,
- converted,
- made over,
- transfigured,
- transformed,
- transmuted,
- transposed,
- transubstantiated.
What is another way metamorphic rocks form?
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.
What is metamorphism in geology?
Metamorphism is a process of mineral assemblage and texture variation that results from the physical-chemical changes of solid rocks, caused by factors such as crust movement, magma activity, or thermal fluid change in the earth. From: Unconventional Petroleum Geology, 2013.
What are the two main agents of metamorphism and what are their respective roles in producing metamorphic rocks?
AGENTS OF METAMORPHISM – The agents of metamorphism include heat, pressure (stress), and chemically active fluids. During metamorphism, rocks are often subjected to all three metamorphic agents simultaneously.
What is metamorphism name the metamorphic equivalents of sandstone and shale?
| Summary Chart of Common Metamorphic Rocks | ||
|---|---|---|
| Original Rocks | Metamorphic Equivalent | Metamorphism |
| sandstone | quartzite | regional & contact |
| shale | slate >> phyllite >> schist >> gneiss | regional |
| limestone | marble | contact |
Where did the word metamorphism come from?
The word metamorphism is taken from the Greek for “change of form”; metamorphic rocks are derived from igneous or sedimentary rocks that have altered their form (recrystallized) as a result of changes in their physical environment.
What is another word for metamorphic?
Some common synonyms of metamorphose are convert, transfigure, transform, transmogrify, and transmute. While all these words mean “to change a thing into a different thing,” metamorphose suggests an abrupt or startling change induced by or as if by magic or a supernatural power.
What are two synonyms transform?
transform
- alter.
- convert.
- mold.
- mutate.
- reconstruct.
- remodel.
- revamp.
- revolutionize.
How are metamorphic rocks produced?
What is the metamorphism phenomenon of the formation of?
Metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). The change occurs primarily due to heat, pressure, and the introduction of chemically active fluids.
