摘　　要：海洋山岩体处于华夏板块与扬子板块的结合带南部,是华南加里东期花岗岩体的典型代表,但其不同的历史阶段研究重点不同。通过对其研究历史进行整理分析发现,有关其岩相学和年代学方面可分为三个阶段;而其构造背景的研究时间跨度长,最终认为岩体形成于同碰撞挤压环境;成矿潜力分析也一直有所涉及,前人认为该花岗岩体周围虽然有一些矿化,但规模不大,而据最新研究成果,则认为该花岗岩体周围地区仍存在形成较大规模矿床的潜力。The Haiyangshan granite,which is located in the southern part of the combination zone between the Huaxia plate and the Yangtze plate,is a typical representative of the Caledonian granite in South-East China.However its research focus is different at different historical stages.Through the analysis of its research history,it is found that its petrographic and chronological aspects can be divided into three stages.The study of its tectonic background has a long time range,and finally it is believed that the rock mass was formed in a co-impact compression environment.Analysis of mineralization potential has also been involved.Predecessors thought that although there was some mineralization around the granite body,it was not large in scale.According to the latest research result,it is considered that there is still a great potential of large-scale deposits in the area around the granite body.
