Explore the concept of metamorphic facies in this comprehensive petrology lecture. Delve into Eskola's metamorphic facies series, examining low and high pressure facies, thermal metamorphism, and various facies types. Learn about intermediate pressure facies, including zeolite, greenschist, amphibolite, and granulite facies. Investigate high pressure metamorphic facies such as blue-schist and eclogite. Discover intermediate grade facies and their mineral compositions. Understand the Barrovian type of metamorphism based on index minerals. Gain insights from Dr. Harel Thomas, a professor of Applied Geology at Doctor Harisingh Gour Vishwavidyalaya, in this 32-minute video designed for undergraduate and postgraduate geology students.
