英文摘要	The Wuliji'Oboo fluorite deposit is a newly discovered deposit hosted by volcanic rocks of the Early Cretaceous Baiyin'gaolao Formation, which are located in the Great Xing'an Range. Fluorite orebodies within this area are controlled by the NNE-trending faults. The sigma REE of fluorite samples ranges from 19.18 to 361.22 ppm, with an average of 131.14 ppm. The homogenization temperatures are concentrated in the ranges of 100-150 degrees C and 230-350 degrees C, while the salinity is concentrated in 0.3-1.0 and 2.0-4.5 wt.% NaCl eqv., and the density has ranges of 0.92-0.96 and 0.75-0.8 g/cm(3), respectively. The delta DV-SMOW values of fluid inclusions within the fluorite range between -122.3 parts per thousand and -105.6 parts per thousand with a mean of -115.36 parts per thousand. The delta O-18(V-SMOW) of fluorite ranges from -12.0 to -8.5 parts per thousand, average is -9.9 parts per thousand. Sm-Nd isotopic data on the fluorite ore yield an isochron age of 122 +/- 15 Ma and have e(Nd)(t) values ranging from +3.15 to +4.16 and (Sr-87/Sr-86)(i) values ranging from 0.704907 to 0.705765. In this contribution, field, petrologic, and geochemical data lead us to the following salient findings: (a) The ore consists of fluorite, quartz, and calcite, with host rock alteration that includes silicification, calcitization, and sericitization. The major element data reveal that the host rocks are a series of highK calc-alkaline rhyolite. The REEs suggest that F-rich fluids in this region might have experienced a long-distance migration. The Tb/Ca-Tb/La diagram confirms a hydrothermal origin for the deposit. (b) Petrographic evidence and fluid inclusions in the fluorites indicate that this deposit might have two ore-forming stages. The ore-forming fluids can be attributed to a NaCl-H2O-F system with moderate-low temperature, low salinity, and low density and have a meteoric water source, with water/rock reaction as the main mechanism for fluorite precipitation. (c) The deposit was formed in an anorogenic within-plate extensional tectonic setting related to the lithospheric thinning occurring after the Mongolian-Okhotsk Ocean closure.
