Listwaenites, located within the Darbut ophiolitic melange belt in the Sartohay region, Xinjiang, are the product of metasomatism from serpentinite in deep levels of shear zones. Serpentinite was transformed into talc schist followed by listwaenite. Listwaenite lenses within the shear zone were deformed as mylonitized listwaenite along rims. Listwaenite is characterized by lower contents of MgO and SiO2, but higher contents of Al2O3 and CaO compared with serpentinite. However, contents of SiO2 and Al2O3 in mylonitized listwaenite are higher than those in listwaenite, whereas MgO is lower than that in listwaenite. Listwaenite has similar characteristics on trace elements as serpentinite, which could be inherited from serpentinite, whereas mylonitized listwaenite is characterized by distinctly different behavior of trace elements from serpentinite. Rare earth elements, high field strength elements and native gold apparently increase in mylonitized listwaenite, implying that these trace elements were concentrated during shearing deformation. Shearing deformation will cause high fluid/rock ratio and facilitate fluid-rock reaction, corresponding to variations on the composition of fluids and physic-chemical conditions in shear zones, accordingly control the decomposition or crystallization of minerals and the mobility of trace elements. Native gold released from serpentinite could be the source for gold mineralization in mylonitized listwaenite.
