The objective of this course is to learn how chemical biological, and geological processes control the distribution of chemical elements on Earth and the solar system. Geochemical processes are central to a variety of environmental issues, including the distribution of CO2 on Earth and the transformation and storage of inorganic and organic contaminants. Simultaneously, geochemical processes are involved in the transformation of natural species, including nutrients, carbon, and minerals.

Chemical reactions occurring at the mineral-fluid interfaces are ubiquitous on Earth and other planets. They control the transport and distribution of a wide range of nutrient, carbon, metal, and organic and inorganic contaminants. In this course, we will learn the fundamental principles concerning mineral surface properties, element distribution in aqueous solutions and at the mineral-water interface, as well as a range of analytical techniques that are relevant to these interfacial reactions.
