Partitioning coefficient of trace elements between mantle minerals and aqueous fluids is important to understand the evolution and tectonics of the Earth. The diversity of the compositions of mantle results from the difference of partitioning coefficients of elements. The composition of aqueous fluids, crystal structure and component of minerals, temperature, pressure, and oxygen fugacity all have effects on partitioning coefficients. Partitioning coefficients of different trace elements in a same mineral or aqueous fluid might have great difference, and which for a same element might vary with different minerals, which cause the differentiation of trace elements in the mantle and result in all kinds of geochemical characteristics mantle. The composition of aqueous fluids has great effect on partitioning coefficient at low temperatures, with increasing temperature, its effect becomes little, whereas the effect of crystal structure and component of minerals becomes important. It should be careful to research the transport and diversity of materials of mantle related with partitioning coefficient owing to these complicated factors.
Key words： Aqueous fluid; Trace element; Partitioning coefficient.; Mantle mineral
