摘　　要：前人对胶莱盆地区域地质工作研究程度较高,地球物理、地球化学、遥感地质等工作也取得一定的成就,为开展铀矿地质勘查工作积累了丰富的地质资料。但对胶莱盆地铀矿工作程度相对较低,对研究区铀矿成矿认识不足。为进一步了解胶莱盆地周缘铀矿化特征、成矿规律和控矿因素,在全面收集、分析胶莱盆地以往地质、矿产、水文、物化探和遥感等资料的基础上,通过类比鄂尔多斯、松辽盆地等中生代盆地铀矿找矿工作,选择EH4、γ能谱测量、氡及其子体测量等找矿手段,分析胶莱盆地铀矿成矿地质条件,厘定找矿目标层位,筛选重点地段开展地质调查、物探测量和槽探、钻探验证等工作,揭示了胶莱盆地铀矿成矿地质背景、赋矿特征,总结了成矿规律和找矿标志,探讨了找矿远景。A high level of research on geological work have been carried out in Jiaolai basin,and many achievements have been gained in geophysics,geochemistry and remote sensing geology.It will provide rich geological data for the exploration of uranium deposits.However,the level of uranium mining work in Jiaolai basin is relatively low,and there is insufficient understanding of uranium mineralization in the research area.In order to further understand the characteristics,laws,and controlling factors of uranium mineralization around Jiaolai basin,based on comprehensive collection and analysis of previous geological,mineral,hydrological,geochemical and remote sensing data,by analogy with the uranium prospecting work in Mesozoic basins in Erdos and Songliao basin,by using EH4,gamma spectroscopy measurement,radon and its daughter measurement and other prospecting methods,geological conditions of uranium mineralization in Jiaolai basin have been analyzed,and target layers for prospecting have been determined.Selecting screen key areas for geological investigation,geophysical measurement,trenching and drilling verification,geological background and ore bearing characteristics of uranium mineralization in Jiaolai basin have been revealed,prospecting laws and prospecting indicators have been summarized,and prospecting prospects and lower work suggestions have been discussed.
