Fundamentals of Petrology: Rock Formation and Earth Processes

Rocks are the foundational record of Earth's history, holding critical clues about deep time processes, tectonic events, and the evolution of our planet. This course introduces you to the essential principles required to read that record. By mastering the core concepts of petrology, you will gain a deep understanding of the mineralogical and chemical makeup of the Earth's crust and upper mantle, enabling you to interpret rock origins and classify them based on their formation environment. What you'll learn: * Understand the basic classification systems and fundamental mineral associations found in igneous, sedimentary, and metamorphic rocks. * Analyze the role of pressure, temperature, and chemical composition in driving rock-forming processes and phase changes within the Earth. * Apply basic thermodynamic principles and phase diagrams to model crystallization and melting behaviors in magmas and metamorphic systems. * Interpret how plate tectonic settings influence rock distribution and metamorphism, linking rock types to specific tectonic environments. * Practice reading and interpreting standard geochemical analysis data, including trace elements, to deduce a rock's provenance and history. * Master the terminology and foundational theories used in modern petrology and geochemistry. The course begins with an introduction to rock-forming minerals and basic rock classification. We then move sequentially through the formation, chemistry, and structure of igneous, sedimentary, and metamorphic rocks, concluding with a detailed examination of their relationship to plate tectonics. This course is designed for absolute beginners in geology or earth sciences. No prior knowledge of chemistry, physics, or geology is required to start learning petrology.
