Isotope Geochemistry is the study of the distribution and abundance of isotopes in various materials, which helps scientists understand geological processes and the history of the Earth. By analyzing isotopic ratios, researchers can gain insights into the origins of rocks, minerals, and even ancient climates. This field plays a crucial role in various applications, including paleoclimatology, geochronology, and environmental science. Isotope Geochemistry allows for the tracing of elements and compounds through different processes, providing valuable information about the Earth's formation and evolution.
