Geochimica et Cosmochimica Acta (GCA)

Geochimica et Cosmochimica Acta is a top-tier scientific journal dedicated to publishing high-quality research on chemical processes that govern the composition and evolution of the Earth and other planetary bodies. Since its establishment in 1950, it has served as a cornerstone for the global geochemistry community, providing a platform for studies ranging from elemental and isotope geochemistry to planetary differentiation and meteoritic chemistry. The journal’s interdisciplinary scope integrates geology, chemistry, physics, and planetary science to explore fundamental processes such as rock-water interactions, mantle and crustal evolution, isotope systematics, and the chemical signatures of planetary bodies beyond Earth. Its content bridges conceptual and empirical advances with rigorous analytical methods, including experimental geochemistry, field studies, and advanced spectroscopic and mass spectrometric techniques. Authors include academic researchers, geoscientists, and earth system modelers addressing topics of both fundamental scientific interest and environmental relevance—from understanding early Earth processes and meteorite formation to contemporary issues such as climate-sensitive biogeochemical cycles. With a high rate of publication and editorial standards that emphasize originality and scientific impact, GCA continues to influence research directions in geochemistry and cosmochemistry worldwide.
