Introduction to Geochemistry: Earth's Chemical Processes

Geochemistry is the key to unlocking the history, composition, and future of our planet. Understanding how chemical elements distribute and react within Earth's crust, oceans, and atmosphere is essential for addressing modern resource and environmental challenges. In this text-based course, you will transition from a curious learner to confidently analyzing geological systems using chemical principles. You will learn to interpret rock compositions, understand water-rock interactions, and evaluate modern environmental challenges. What you'll learn: 1. Understand foundational geochemical concepts, including element distribution, thermodynamic laws, and chemical equilibrium. 2. Analyze the chemical composition of igneous, sedimentary, and metamorphic rocks. 3. Explore aqueous geochemistry to evaluate water quality, weathering processes, and mineral solubility. 4. Apply isotope geochemistry principles to determine the age of geological materials and track environmental changes. 5. Examine modern environmental geochemistry challenges, including contaminant transport and carbon capture and storage (CCS) technologies. 6. Practice interpreting real-world geochemical data sets through structured, written exercises. The course begins with core definitions and chemical fundamentals before guiding you through rock chemistry, water systems, and advanced topics like isotopic dating and modern carbon sequestration techniques. This course is designed for absolute beginners, environmental science students, and curious minds who want to understand the chemistry of the Earth without needing prior advanced laboratory experience.
