英文摘要	Lijiabian Ti-Fe deposit is located in Shanyang-Fengzhen tectonic melange belt along the southern margin of Shanyang-Zhashui ore concentration area, South Qinling orogen. Ti-Fe mineralization is characterized by titanomagnetite and ilmenite, disseminated in cumulate gabbro. Mineral association and texture coevally indicate that Lijiabian Ti-Fe deposit is a typical magma differentiated deposit. The mineral and whole-rock geochemical data suggest that the host rocks of Lijiabian Ti-Fe deposit have a dual magmatic character of island arc calc-alkaline and ocean within-plate basalts. SHRIMP zircon U-Pb data of gabbro yield a weighted mean Pb-206/U-238 age of 621 +/- 6Ma. Inherited zircons demonstrate gabbro magma captured old mid-acid volcanic arc rock in Late-Neoproterozoic. These features demonstrate that the Lijiabian Ti-Fe deposit formed in a back-arc basin setting.
