Palaeogeochemia
Palaeogeochemia is an interdisciplinary field that combines principles of geochemistry and geology to study the chemical composition of ancient Earth materials and environments. It focuses on reconstructing past geological conditions, including atmospheric composition, ocean chemistry, and the evolution of the biosphere, by analyzing the chemical signatures preserved in rocks, minerals, and fossils.
Key techniques employed in palaeogeochemia involve isotopic analysis, trace element studies, and the examination of organic
The field contributes to understanding major Earth system processes and their evolution. This includes investigating the
