摘　　要：地球化学参数是与气候、环境、生态、资源等关系最为密切的指标之一,过去几十年中在矿产资源勘查、环境保护等领域得到了充分应用。海洋地球化学调查和研究工作也在不断深入,但缺少类似陆地地球化学填图那样系统的专项工作,对全球海洋资源、环境的评估与研究的支撑作用仍不够明显,元素含量及同位素组成等在全球海洋中的分布趋势仍认识不足。笔者对全球海洋沉积物、岩石、结核结壳和水体的无机地球化学调查进展进行了系统梳理,全面介绍了目前已开展的工作和取得的主要成果,以期为全球尺度地球化学研究提供重要参考。Geochemical parameters, which are closely related to palaeo-climate, palaeo-environment, palaeo-ecology and geo-resources, have been widely applied in mineral resources exploration and environmental protection in the past decades.Marine geochemical investigation and research are also deepened and advanced.However,comparing the status on land, systematic special works,such as land-based geochemical mapping, are still lacking.Its supporting function to global marine resources hunting and environment assessment remains not so obvious,and the distribution pattern of element contents and isotopic composition in the global ocean is still not fully understood.In this paper, the progress of inorganic geochemistry investigation of marine sediments, rocks, concretion crusts and water bodies in the recent years is systematically reviewed. This work will provide important reference for global scale geochemical research in the future.
