英文摘要	The giant Bayan Obo REE-Nb-Fe mine is currently the largest REE deposit in the world. A large area late Paleozoic granitoids are distributed in the southeast of east open pit of the mine. The granitoids intruded directly into the ore-bearing dolomite (H(8)), and produced intense skarnization. Moreover, at 650 similar to 660m of the drill core on 22 line and 1598m level flat in the south of east open pit, we firstly found skarnization rocks. Single grain and low background Rb-Sr isochrone dating on phlogopite in skarn gives 309 +/- 12Ma. Considering the intruded contacting relationship, the late Paleozoic granitoids, already extended to the under part of REE ore bodies, must be posterior to the latest intense REE mineralization, and is only a destructive tectonic and magmatic activity.
