摘　　要：新疆哈密东戈壁斑岩型钼矿为特大型钼矿床,钼金属资源量50.8万t。在勘探过程中采集了一批与成矿有关的流体包裹体测温、测压样品,获得了与成矿作用有关的较为丰富的温度、压力数据,为成矿深度研究提供了基础资料。本文利用平衡温度/压力进行成矿深度计算的方法,使成矿深度的计算更加量化、数据更具体,并与地层厚度累加法计算结果进行对比,指出东戈壁钼矿成矿深度6.7 km,为超深成热液矿床。East Gobi porphyry molybdenum deposit in Hami,Xinjiang is an extra-large molybdenum deposit.During the process of detailed survey and exploration,a batch of fluid inclusion thermometry and pressure measurement samples related to mineralization were collected and abundant temperature and pressure data related to mineralization were obtained.This article uses the method of calculating the depth of mineralization based on equilibrium temperature/pressure to make the calculation of the depth of mineralization more quantitative and specific.The results are compared with those obtained by the method of cumulative thickness of strata,indicating that the mineralization depth of East Gobi molybdenum deposit is 6.7 km,and it belongs to an ultra-deep hydrothermal deposit.

关 键 词：东戈壁 成矿深度 平衡温度/压力
