摘要：
The Jinchuan ultramafic intrusion in western China hosts the third-largest magmatic Ni-Cu deposit in the world. The crystallization age of the intrusion has long been debated. Here, we present a U-Pb ID-TIMS zircon age of 831.8 +/- 0.6 Ma obtained on thermally annealed and chemically etched zircons from a lherzolite sample. The coexisting baddeleyite in the sample is indistinguishable from the age of zircon. Our new results confirm that the emplacement of the Jinchuan ultramafic intrusion was temporally related to the breakup of the Rodinia supercontinent.
