Metamorphic rock naming can be based on texture, protolith, metamorphic facies, and / or the locations in which they are found.
12.
The formation lends its name to the term describing high-pressure regional metamorphic facies, the "'Franciscan facies series " '.
13.
She was seen as a leading expert on metamorphic facies, which is a set of mineral clusters that was formed under similar temperatures and pressures.
14.
Each of these metamorphic facies is marked by the presence of a specific stable mineral assemblage, recording the metamorphic conditions undergone but the subducting slab.
15.
It occurs in granitic and pegmatite masses, in some hydrothermal vein deposits and forms part of the typical greenschist metamorphic facies for rocks of originally basaltic composition.
16.
"' Pentti Eelis Eskola "'( 8 January 1883 6 December 1964 ) was a Finnish geologist who developed the concept of metamorphic facies.
17.
Phyllites are said to have a texture called " phyllitic sheen, " and are usually classified as having formed through low-grade metamorphic conditions through regional metamorphism metamorphic facies.
18.
Apart from the metamorphic facies of a rock, a whole terrane can be described by the abbreviations LT, MT, HT, LP, MP, HP ( from low, medium or high; pressure or temperature ).
19.
Likewise, metamorphic facies, which show the degree to which a rock has been exposed to heat and pressure and are therefore important in classifying metamorphic rocks, are determined by observing the mineral phases that are present in a sample.
20.
His application and expansion of Pentti Eskola's concept of metamorphic facies led to his publication of " Mineralogical and Structural Evolution of Metamorphic Rocks ", the book that established his position in the field of petrology and was a great influence on a generation of geologists.
