What is the difference between metamorphic grade and metamorphic facies?
A metamorphic grade takes into account only the change in temperature while a metamorphic facies is more specific by showing the change in temperature in relation to the change in pressure and depth. There are three grades: low (250°C-400°C), intermediate (400°C-600°C) and high (above 600°C). Although there are many facies, the major ones are zeolite, hornfels, greenschist, amphibolite, blueschist, eclogite, and granulite. This allows for geologist to easily locate where a metamorphic rock was formed.
What is a hydrochemical facies in hydrogeology?
A hydrochemical facies in hydrogeology refers to a distinct group of water samples with similar chemical compositions. These facies are used to classify groundwater based on their major ion concentrations, providing insights into the geochemical processes and water-rock interactions occurring in the subsurface. By studying hydrochemical facies, hydrogeologists can better understand groundwater quality, flow patterns, and sources of contamination.
Where can amphibolite be found?
Amphibolite can be found in regions with high-grade metamorphic rocks, typically in mountain belts or areas with tectonic activity. Examples include the Appalachian Mountains in the United States, the Scottish Highlands, the Alps in Europe, and some parts of Japan and New Zealand.
Is marble igneous or sedimentary?
Marble is the metamorphosed result of limestone. Therefore, marble is metamorphic.
Is Slate is metamorphic?
yes, slate is metamorphic rock
What is a blueschist?
A blueschist is a variety of metamorphic rock containing glaucophane.
Which metamorphic facies represents the highest temperature and pressure conditions?
It's eclogite facies.
Which metamorphic facies is associated with subduction zones?
blue schist facies

What can metamorphic rocks change into?
Greenschist, blueschist, zeolite, granulite and eclogite high grade metamorphic rocks.
What is the difference between facies in sedimentary rocks and facies in metamorphic rocks?
Most regional metamorphic rocks are formed in conditions within this range of geothermal gradients, passing through the greenschist facies to the amphibolites
Metamorphic rocks with the same mineral assemblages belong to the same?
metamorphic facies. This indicates that these rocks formed under similar pressure and temperature conditions despite coming from different locations.
What are metamorphic facies?
Depending on the pressure and temperature conditions under which a rock undergoes metamorphism, differing groups of minerals tend to form. These differing groups formed under differing conditions are known as metamorphic facies. For more information, please see the related link.
Which metamorphic rocks form under high stress and low to moderate temperatures in subduction zones?
Blueschist
Which of the following metamorphic facies are characteristic of burial metamorphism?
Zeolite and prehnite-pumpellyite facies are characteristic of burial metamorphism. These facies typically occur at low to medium pressures and temperatures, representing the early stages of metamorphism when sediments are first buried and compacted.
What has the author Hans-Martin Albat written?
Hans-Martin Albat has written: 'The Proterozoic granulite facies terrane around Kliprand, Namaqualand Metamorphic Complex' -- subject(s): Facies (Geology), Geology, Granulite, Stratigraphic Geology
Basalt can change into what metamorphic rock?
When basalt undergoes metamorphism, it can change into a metamorphic rock called greenstone. Greenstone is a fine-grained metamorphic rock that forms from the alteration of basalt through metamorphic processes like recrystallization and the growth of new minerals.
