摘要

Based on previous researches, other direct and indirect factors for variation of REE in shear zones are summarized, including the “extraction” of melt to REE under strong stress, the residues of accessory minerals, the dynamic control of oxygen fugacity on variation of REE, the effective fluid filtration with high water/rock ratio, the dynamic changes of distribution coefficients, and the driving of stress on the elements.
