摘　　要：通过检索国内外有关古岩溶的文献,列举了古岩溶的主要识别标志。在此基础上,对国内外关于古岩溶和古岩溶岩研究的方法和技术手段进行总结,主要讨论了古岩溶岩的地球化学研究方法。通过古岩溶岩中稀土元素、微量元素地球化学特征分析,得出古岩溶形成过程中古流体性质、古水文条件等,对预测古岩溶储层以及与古岩溶有关的矿床的分布规律提供地球化学信息,从而有效地、经济地勘探和开发油气田和相关矿产资源。By reviewing the related literature of paleokarst rocks,I enumerates the main identification marks of the paleokarst rocks.On the basis of this,this paper summarizes the paleokarst and the paleokarst rocks research methods and technical means,and mainly discusses the geochemical methods of the paleokarst rock.By analysing the rare earth elements and the trace elements,the fluid properties and paleo-hydroloic condition can be concluded,and the geochemical information of the paleokarst reservoir and ore deposits distribution are also provided,which can help to explore and develop the oil and gas fields as well as related mineral resources effectively and economically.
