A PROGRESS REVIEW OF THE MARINE GEOCHEMICAL SURVEY IN THE WORLD

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.
