Metamorphic Rocks and Their Properties

The video tutorial covers the formation of metamorphic rocks, focusing on the processes of heat and pressure that lead to recrystallization without melting. It explains regional metamorphism, which occurs on a large scale during continental collisions, and contact metamorphism, which happens on a smaller scale due to igneous intrusions. The video also discusses the textures of metamorphic rocks, distinguishing between foliated and non-foliated types, and provides examples of metamorphic rocks and their parent rocks.
