EAPS 51 Isotope Geology
Isotope Geology is the study of chemical elements and their natural variations. By measuring and interpreting the isotopic compositions of rocks, minerals, and other materials, we unlock secrets about our planet's past. Isotopes are powerful tools that allow us to determine the age of the Earth, reconstruct ancient CO2 levels and temperatures, and gain insights into the origin and evolution of life itself. We can even trace the origins of elements to distant stars, understand meteorite impacts, and address modern environmental challenges. In this course, we will first master the fundamentals of isotope systematics, then explore the major geological and geochemical breakthroughs that have been made with this powerful scientific tool.
