摘　　要：论述了地质推断法、流体包裹体法和裂变径迹法等研究方法及发展动态。地质推断法是以成矿地球动力学环境造成控矿构造、矿石矿物组合、地球化学元素组合、成矿岩体、矿体延深等地质依据来推断成矿时的深度;流体包裹体法是通过测定包裹体的均一温度、盐度,计算其密度、压力,进而获得成矿深度;裂变径迹法计算裂变径迹年龄、隆升速率、剥蚀速率以及剥蚀量等参数,进而讨论成矿深度。最后评述了热液铀矿床成矿深度研究的现状。In this paper,geological deduction,fluid inclusion and fission track and their development are discussed in detail.Geological deduction is a method to inferring the metallogenic depth by studying metallogenic geodynamic environment and the ore controlling structures, ore mineral composition, geochemical element composition, ore forming rocks and ore body extension.Fluid inclusion is a method to acquire the metallogenic depth by measuring the homogenization temperature,salinity,and calculating the density and pressure.Fission track is a method to discuss the metallogenic depth after cal-culating the parameters such as fission track age, uplifting rate, erosion rate and erosion quantity.Finally,status and main points of the metallogenic depth researches of hydrothermal uranium deposits are commented.
