| 摘 要： | 东戈壁斑岩型钼矿床是在新疆境内发现的第一个特大型钼矿,钼资源量(331)+(332)+(333)约503 474.66 t,矿石平均品位0.115％.矿床的形成与隐伏斑状花岗岩体有关,矿化的主要载体是以石英脉、钾长石脉为主的各种脉体,即该矿床兼具斑岩型及脉型矿床的特征.通过对含矿脉体中流体包裹体的研究,初步确定矿床的成矿温度为197～390℃,成矿压力为531.04×105～752.10×105 Pa,成矿深度为1.68～2.39 km,成矿流体为富含多种气态组分的低盐度流体；成矿时代为华力西晚期；矿床成因类型应为浅成中高温岩浆热液型钼矿床.

| Abstract: | The East Gobi porphyry molybdenum deposit is a newly discovered super-large ore deposit in Xinjiang.Mo metal resources/reserves(331) +(332) +(333) is estimated at 503 474.66 tons with an average grade of 0.115% Mo.Formation of the Mo deposit is related to a concealed porphyritic granite body.Mineralization occurs mainly in veins dominated by quartz vein and K-feldspar vein so the deposit shares characteristics of quartz vein type deposit and porphyry deposit.Study on fluid inclusions shows that the deposit is a meso-high temperature magmatic hydrothermal fluid Mo deposit formed at shallower depth and at temperature 197 to 390 ℃ and pressure 531.04×105 to 752.10×105 Pa in Hercynian Period. |
