The blueschist facies is a metamorphic realm of?
high pressure but relatively low temperature
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 syn rift sediments?
A sediment deposited at the same time as rifting affected the depositional area
What does a hydrologist do?
Hydrogeology is a branch of Earth science, it is mainly based on the study of ground water movement over soil and rocks.Hydrogeology is the study of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth's crust.
Where can amphibolite be found?
Amphibolite is a metamorphic rock consisting of amphibole. It is formed within the pressure-temperature limits of amphibolite facies usually anywhere from 400 to 500 degrees Celsius.
Hydrogeology is the study of what?
Hydrogeology is the study of groundwater.
Which metamorphic facies is associated with subduction zones?
blue schist facies
What is the meaning of facies?
In geology, a facies is a body of rock with specified characteristics.
When was Hydrogeology Journal created?
Hydrogeology Journal was created in 1992.
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
What is the texture of hornfels?
I too would like an answer to this question as it seems hornfels could be of varying grade dependant on the temperature. The facies of contact metamorphism progress in temperature at relatively low pressure from the Albite-Epidote Hornfels Facies to the Hornblende Hornfels Facies, to the Pyroxene Hornfels Facies. It seems that hornfels do have differant grades.

What is a facies fossil?
Is fossil which is present in more than one facies or environment. Body of rock with features that distinguish it from other bodies of rock
Which metamorphic facies represents the highest temperature and pressure conditions?
It's eclogite facies.
What does facies mean?
Prima facie is Latin for "at first sight". (The word facies in Latin is literally "form" or "shape", but has extended meanings of "face" and "appearance").

What is coarse facies?
Facies are your facial expressions (http://en.wikipedia.org/wiki/Facies), which can indicate conditions such as Williams syndrome (http://en.wikipedia.org/wiki/Williams_syndrome) and other forms of mental retardation. Coarse facies, in particular, are often associated with mental retardation. Coarse facies simply means that the facial expressions are coarse, which could represent congenital hypothyroidism (http://bdoza.blogspot.com/2008/12/casecongenital-hypothyroidism.html) or spondyloepimetaphyseal dysplasia (http://www.nature.com/ejhg/journal/v13/n5/fig_tab/5201339f1.html). Coarse facies, while often associated with mental retardation, is not the sole indicator, however, and other tests should be run as well.
