blue schist facies


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.


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.

What are facies changes in sedimentary rocks?

Facies changes in sedimentary rocks refer to transitions in the characteristics of sedimentary deposits, such as grain size, composition, and sedimentary structures, over time and space. These changes can indicate shifts in environments of deposition, such as from a river to a delta or from shallow to deep marine settings. By studying facies changes, geologists can reconstruct the environmental conditions that existed in the past.


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.


The blueschist facies is a metamorphic realm of?

The blueschist facies is a metamorphic realm of low-temperature, high-pressure conditions typically found in subduction zones. It is characterized by the presence of minerals such as glaucophane and lawsonite, and indicates that rocks have undergone metamorphism at depths of 15-30 kilometers. This facies is important for understanding the processes of subduction and the formation of mountain belts.
