英文摘要The large Jiguanshan porphyry Mo deposit, with more than 100 Mt of ore and grades ranging from 0.08% to 0.11%, is located in the newly identified Xilamulun metallogenic belt along the northern margin of the North China Craton. The Mo mineralization is predominantly disseminated in the host granite porphyry, but locally occurs as stockworks in lithic tuff and rhyolitic rocks. Ar-40/Ar-39 dates of samples from groundmass material in the host granite porphyry, post-ore diabase, and quartz porphyry dikes show plateau ages of 155.1 +/- 1.9, 149.4 +/- 0.9, and 147.6 +/- 0.9 Ma, with inverse isochron ages of 156.0 +/- 1.8, 149.3 +/- 1.3, and 148.3 +/- 1.2 Ma, respectively. Seven samples of disseminated molybdenite yielded a weighted average Re-187-Os-187 age of 155.3 +/- 0.9 Ma, whereas six veinlet-type molybdenite samples yielded a weighted average Re-187-Os-187 age of 153.0 +/- 0.9 Ma, providing direct timing constraints for the Mo mineralization at 153-155 Ma. The regional geological setting together with the emplacement of post-ore diabase and quartz porphyry dikes in the Jiguanshan deposit, are indicative of an extensional regime in Late Jurassic, which was probably linked to lithospheric extension in northeast China.
