摘　　要：湖南会同早禾田矿床是湘西新元古界中发现的铀矿床,是中南地区唯一产在板溪群变质岩中的热液型铀矿床。铀矿体赋存在硅化断裂带及其两侧层间断裂破碎带中,呈似层状、透镜状、纺缍状,产状与地层及断裂构造基本一致。通过对本区地质特征、矿床地质特征的研究,分析了控矿规律,建立成矿模式,初步认为该矿床属于碳硅泥岩型沉积-热液-淋积亚类铀矿床。Zaohetian deposit in Huitong County of Hunan Province is a uranium deposit found in the Neoproterozoic Erathem in West Hunan.It is the only hydrothermal uranium deposit in the metamorphic rocks of Banxi group in the central-south area.The uranium ore body exists in the silicified fault zone and the interlayer fault fracture zone on both sides,which is layered,lenticular and spindly,and the occurrence is basically consistent with the stratum and fault structure.Through the summary of the geological characteristics of the deposit in this area,the ore controlling regularity is analyzed and the metallogenic model is established.It is preliminarily considered that the deposit belongs to sedimentary-hydrothermal-eluvial type uranium deposit.
