Since the creation of the Solar System and Earth 4.5 billion years ago, Earth’s natural processes have differentiated the chemical elements, generating distinct differences in composition between the oceans and the atmosphere, and Earth’s crust, mantle and core. These differences allow Earth Scientists to understand and quantify these processes, as well as track the rocks and deposits formed out of these processes. This course will focus on the application of geochemistry to understand Earth processes, such as the generation of magma and volcanic eruptions, the formation of ore bodies, the role of oxygen in ocean sediments, common analytical methods employed in Earth Science and the use of isotopes to track changes to Earth over time.
