国际地球化学填图走向新阶段

International geochemical mapping moves towards a new phase

国际地球化学填图的主要目的在于了解自然界存在的各种化学元素在地球表层的分布和变化,为资源评价、环境保护和全球变化等提供基础资料。这里简要介绍了国际地球化学填图的历史和取得的阶段性进展,叙述了IGCP 259和IGCP 360计划及由两个计划推动的欧洲、美国、澳洲和中国地球化学填图计划的概况。2016年为推动国际地球化学填图工作成立了联合国教科文组织全球尺度地球化学国际研究中心,该中心落户在自然资源部中国地质科学院地球物理地球化学勘查研究所,在中心成立的同时发起了“化学地球”国际大科学计划。大科学计划实施至今已取得重大进展,标志着国际地球化学填图走向新的发展阶段。

International geochemical mapping can help people understand the geochemical distribution and variation of all elements in the earth’s surface from a macro perspective,and provide important reference for solving global resource and environmental problems.The main content of this paper is the history and progress of international geochemical mapping.A brief introduction is given to the IGCP 259 and IGCP 360 plans and the geochemical mapping projects in Europe,USA,Australia and China promoted by the two plans.In 2016,the UNESCO international centre on global-scale geochemistry was established to promote international geochemical mapping,and the’chemical earth’grand scientific program was launched.The implementation of the’chemical earth’has made great progress,marking a new stage of international geochemical mapping.
