regional metamorphism of dolomite and limestone

Metamorphic rock

The mineral assemblages are quite similar to those found in regional greenschist-facies metamorphism except for the presence of low-pressure phases such as andalusite Characteristic minerals include quartz muscovite biotite chlorite andalusite actinolite calcite dolomite albite and epidote...

Contact Metamorphism Vs Regional Metamorphism

Regional metamorphism includes any metamorphic process that occurs over a large region It is therefore the most widespread and common type of metamorphism A rock is squeezed under directed pressure during metamorphism it is likely to be deformed and this can result in a textural change such that the minerals are elongated in the direction perpendicular to the main stress...
