英文摘要The Dongfengbeishan porphyry Mo deposit is located to the southeast of the Lesser Xing'an Range-Zhangguangcai Range metallogenic belt in NE China. LA-ICP-MS zircon U-Pb dating of the Beishan monzogranite yields an age of 194.75 +/- 0.81 Ma. Five molybdenite samples define a Re-Os isochron age of 194.0 +/- 2.0 Ma, suggesting that mineralization was associated with emplacement of the Beishan monzogranitic pluton. Monzogranite samples are classified as high-K calc-alkaline and are relatively enriched in light rare earth elements, depleted in heavy rare earth elements, Nb, Ba, P, Sr, Ti, and Zr, and yield negative Eu anomalies. These characteristics are interpreted to record fractional crystallization of the parental magmas. Zircon (epsilon Hf)(t) values for Beishan monzogranite samples range from + 8.2 to + 15.9, and two-stage model ages (T-DM2) range from 217 to 711 Ma, indicating that the parental magma was produced during partial melting of juvenile lower crust. Combined with previous studies, our data suggest that the Dongfengbeishan porphyry Mo deposit was associated with westward subduction of the paleo-Pacific plate in the Early Jurassic.
