摘　　要：龙口-土堆金矿区位于胶莱盆地东北缘,控制矿体主要赋存在-400 m标高以上的浅部,矿体规模相对较小、不连续,而其周边的辽上、西涝口金矿区在-500 m标高以下均实现了找矿突破,且矿体规模厚大。通过对比龙口-土堆金矿床与辽上、西涝口金矿床的地质特征,并结合区域成矿背景,认为龙口-土堆金矿区深部具有较大的成矿潜力,且深部找矿应以牧牛山岩体与荆山群地层接触带为主。The Longkou-Tudui Gold District is located in the northeast of the Jiaolai Basin. The district controlled ore bodies mainly spread shallower than the-400 m elevation and are small-scale and discontinuous. However,exploration breakthroughs have been made in the adjacent Liaoshang and Xilaokou gold districts below the-500 m elevation and the ore bodies are thick and large-scale. By comparing the geological characteristics of the Longkou-Tudui Gold Deposit and the Liaoshang and Xilaokou gold deposits and based on regional metallogenic settings,it is indicated that there are great resource potentials in the deep levels of Longkou-Tudui Gold District and the deep prospecting should be carried out on the contact zone of Muniushan rock mass and Jingshan group strata.
