Metamorphic Petrology- Types of Metamorphism, Protoliths, Textures, & Classification | GEO GIRL

You ever want a crash course on metamorphic petrology? This video is for you! We go over what metamorphism is, metamorphic environments and types of metamorphism (regional metamorphism, contact metamorphism, burial metamorphism, hydrothermal metamorphism, impact metamorphism, & dynamic metamorphism), the 3 main goals of metamorphic petrology (determining protoliths, conditions of metamorphism and structural deformation history of the rock), examples of common metamorphic rocks and their protoliths (marble, quartzite, gneiss, slate, schist, eclogite, greenschist, & anthracite coal), primary and secondary textures (primary textures like igneous and sedimentary textures that are save through metamorphism, and secondary textures that are caused during static or tectonic metamorphism) and the information we can gain from these metamorphic textures, the difference between linear and planar features in metamorphic rocks like lineations, foliations, and schistosity, and lastly, we cover both the structural and compositional classification of metamorphic rocks, and I give you my tips and tricks for identifying metamorphic rocks in metamorphic petrology lab based on my experience. ;)
