Abstract

Abstract

Fluorite is main vein mineral in Maoniuping REE deposit, whose formation ran through the whole mineralization process. So the isotopic study plays an important role in probing the source of fluorite and REE ore-forming fluid. The Sr, Nd isotopic composition of 6 fluorite samples from Maoniuping orefield are similar. According to Sr, Nd isotopic data of the wall rocks (carbonatite-syenite, granite), it is shown: that different REE distribution fluorites from different colors and ore type are the products of the same source; REE ore-forming fluids come from the enriched mantle and are closely related with magma action of carbonatite-syenite.
