摘　　要：鹿井矿田是我国重要的铀矿田之一,均属花岗岩热液型铀矿床,分为岩体内带型、岩体外带型、岩体内外接触带型铀矿床。岩体内外接触带型铀矿为近十年来区内找矿科研投入较大、成果突出的铀矿床类型,为近年新定名的铀矿床类型。岩体内外接触带型铀矿床既有岩体内带型、岩体外带型铀矿床特征,又有其独特的特征;属于同一成矿作用在不同的构造部位形成的铀矿床。本次研究总结了区内岩体内外接触带型铀矿床铀矿化特征、成矿规律、控矿因素,提出了本区下一步找矿方向,为该区今后铀矿勘查、综合找矿和科研工作提供了指导与借鉴。Lujing ore field is one of the important uranium ore fields in China, which belongs to granite hy-drothermal uranium deposits. It is divided into intra-rock type, extra-rock type and intra-rock contact zone type. The contact zone type uranium deposit inside and outside the rock mass is a type of uranium deposit with large investment and outstanding achievements in prospecting and scientific research in the past decade. It is a new type of uranium deposit in recent years. The uranium deposit with contact zone inside and outside the rock mass has not only the characteristics of the uranium deposit with contact zone inside and outside the rock mass, but also its unique characteristics. It belongs to uranium deposits formed by the same mineralization in different structural parts. This study summarizes the uranium mineralization characteristics, metallogenic regularity and ore-controlling factors of uranium deposits in the inner and outer contact zones of rock mass in the region, and puts forward the next prospecting direction in the region, which provides guidance and reference for future uranium exploration, comprehensive prospecting and scientific research in the region.
