Explore the fascinating world of metamorphic rocks in this comprehensive 32-minute video lecture on the metamorphism of basalt and gabbro. Learn about the predictable mineral assemblage transitions that occur in mafic igneous rocks under varying pressure and temperature conditions. Discover the characteristics of different metamorphic facies, including greenschist, blueschist, amphibolite, granulite, and eclogite. Understand the key minerals and textures associated with each facies, and how they relate to the original basalt or gabbro protolith. Gain insights into the zeolite and prehnite-pumpellyite facies, and examine the relationship between iron, magnesium, calcium, and aluminum content across different metamorphic facies. Utilize the provided flow chart to visualize the progression of metabasite minerals throughout the metamorphic process. Access additional resources, including recommended textbooks, websites, and thin section atlases, to further enhance your understanding of metamorphic petrology. Read more
