<p><b>Using isotopes as a tool for understanding Earth processes</b> <p>From establishing the absolute age of the Earth to providing a stronger understanding of the nexus between geology and life, the careful measurement and quantitative interpretation of minor variations in the isotopic composition of Earth’s materials has provided profound insight into the origins and workings of our planet. <p><i>Isotopic Constraints on Earth System Processes </i>presents examples of the application of numerous different isotope systems to address a wide range of topical problems in Earth system science. <p>Volume highlights include: <ul> <li>examination of the natural fractionation of non-traditional stable isotopes from theoretical and experimental to petrologic and metabolic </li> <li>application of isotopes to understand the origin and evolution of magmas that give rise to the Earth’s oceanic and continental crust</li> <li>utilizing isotopes to understand volcanic systems, from the genesis of large ignimbrites to monitoring of active volcanos</li> <li>application of isotopes to interrogate and understand Earth’s Carbon and Oxygen cycles through geologic time </li> <li>examination of the geochemical and hydrologic processes that lead to isotopic fractionation in metal, metalloid, and actinide isotope systems</li> <li>application of isotopic reactive transport models to decipher hydrologic and biogeochemical processes </li> </ul> <p>The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.
