艾姆劲钼金矿床位于新疆博罗霍洛地区东北段。钼金矿体受侵入于中泥盆统拜辛德组陆源碎屑岩的黑云母花岗岩和北东向构造控制，先后经历了岩浆晚期、热液期和表生期等3期成矿作用，具有岩浆热液型矿床特点。对采集于不同矿体的辉钼矿进行 Re-Os同位素测定，获得等时线年龄为（302.4±2.4） Ma， MSWD＝0.75，该年龄与赋矿黑云母花岗岩的成岩时代一致，表明艾姆劲钼金多金属矿床形成于晚石炭世，与黑云母花岗岩侵入活动有关。

The Aimujin Mo-Au polymetallic deposit, situated in the northeast region of Boluohuoluo region in Xinjiang, is a new metallogenic region with great potential of mineral prospection.The deposit of MoA-u ore -body is strictly controlled by NE fault and the biotite granite and intruded into Baixinde group stratum .The Mo-Au polymetallic deposit developed in three mineralization stages.They are late magmatic, hydrothermal and Supergene enrichment, with the metallogenic characteristics of magmatic hydrothermal type .In author's collec-tion of molybdenites from different orebodies, through the isotope determination of molybdenites Re-Os, accu-rate isochrones age is found (302.4 ±2.4)Ma, MSWD=0.75.The result shows that the deposit formed in the late carboniferous, and related to the intrusion function of biotite granite.
