Stable Isotope Geochemistry
Stable isotope geochemistry studies the distribution of non-radioactive isotopes—versions of elements with different atomic weights—in rocks, minerals, and other Earth materials. By examining variations in isotopic ratios, scientists can uncover information about processes like Earth's formation, climate changes, and volcanic activity. These isotopic signatures act like natural tracers, helping us understand the history and evolution of geological systems. Because stable isotopes do not decay over time, they provide reliable insights into natural phenomena and environmental conditions across different periods.
