A Review on the Elemental and Isotopic Geochemistry of Gallium

Gallium exhibits weak metallic properties owing to its proximity non-metals in the periodic table, yet is volatile extra-terrestrial bodies and fairly reactive nature. It has been used extensively elucidate Solar System evolution, planet interior differentiation, terrestrial processes. However, Ga speciation transformation various planetary compartments dynamics of trans-reservoir pathways remain be fully resolved. Although recent studies development modern analytical techniques for isotopes have markedly improved our understanding geochemistry, a systematical summary state-of-the-art knowledge appears long overdue. Here we provide an overview geochemical different reservoirs, including meteorites Earth's exterior compartments, timely review isotopic geochemistry. We also first tentative estimate total masses flux, based on published data. This compilation reveals clearly lack geochemistry data interior, imbalance oceanic budget potential implications isotopes, stimulating future systematic geosciences related fields.
