封面故事：56种关键元素在中国的分布。关键资源已成为工业4.0不可替代的原材料, 是现代社会所必需的物质基础。通过行之有效的地球化学方法, 绘制和研究关键元素在全国尺度、区域尺度、矿区尺度到纳米尺度的空间分布, 圈定了一批稀土、锂、铀、金、铜等关键元素超常富集区。发展了元素大深度迁移机理, 建立了三维地球化学探测模型, 经钻探验证, 发现1000~3000 m深度金矿体, 实现了从浅表矿到千米深度矿产资源地球化学探测能力的飞跃。本专辑介绍了中国地质科学院地球物理地球化学勘查研究所王学求等研究团队在关键资源地球化学勘查中取得的最新成果。(图片提供: 王学求)
Cover Story：Distribution of 56 critical elements in China. Critical minerals are required for the materials of industry 4.0 and for modern societies for development, prosperity, and security. Geo-chemistry is a cost-effective methods for mapping national, regional，local and nano-scale distribu-tion of critical elements, and for delineation of super-enriched concentration targets for REEs, lithium, uranium, gold, copper and some other elements. 3-D geochemical patterns on the basis of vertical dispersion mechanism have made great contribution to deep-seated gold deposits at the depth of 1000~3000 meters by drilling verification. China is in leading position in research on spatial distribution of critical elements and deep-penetrating geochemical exploration. This issue reports the newest achievements and progresses of geochemical exploration for critical elements contributed by WANG Xue-qiu’s team, Institute of Geophysical and Geochemical Exploration, CAGS.
