| 中文摘要:“向地球深部进军是我们必须解决的战略科学问题”是习近平总书记提出的重要论断, 也是国家对地学工作者提出的新要求。深部地质作用地球行星作为载体在太阳恒星系统及其更大尺度空间综合作用的结果。从短周期的月球-地球作用的潮汐, 到地球-太阳作用的四季更替, 再到较大尺度的冰期-间冰期更替, 乃至更大周期, 无一不影响到地球自身, 诸如膨胀-收缩, 海平面升降, 活火山爆发与宁静, 成灾-成矿/成藏, 生存环境的毁灭与再造, 深刻地影响着我们地球家园的生态环境。战略性关键矿产多受控于深部地质作用。金刚石产在金伯利岩-钾镁煌斑岩-橄榄玄武岩中, 新能源矿产铀矿产于深源断裂控制的火山岩或砂岩中, 锂-铷-铯和铌-钽-锆-铪等稀有金属多产于深源流体控制的伟晶岩中, 金、银、铂族元素、钴、铼等稀贵金属多受控于深源流体, 稀土元素多产于深源的碳酸岩-碱性杂岩中。这些矿产大多数对于新兴产业是必不可少的原料。同时, 深部地质作用及其浅部产物是人类认识地核-地幔物质组成的窗口。战略性关键矿产历史性地将深部地质作用研究的重任交给地学工作者。
近年来, 多家科研单位、高等院校和地勘单位对深部地质作用及相关的战略性关键矿产开展了地质调查和科学研究, 在金伯利岩、钾镁煌斑岩、玄武岩等深部地质作用和金刚石、贵金属、铀矿、稀土稀有稀散矿产等成矿作用等方面取得了一系列新进展。为了更好地推动深部地质作用和战略性关键矿产相关的学术研究和应用转化应用, 服务国家需求, 《地球学报》组织了“深部地质作用及战略性关键矿产”专辑, 服务于深部探测和战略性关键矿产(金刚石、铀矿、稀土-稀有-稀散-稀贵金属)相关研究和勘查工作的专家、学者。 |

| Abstract:“To advance to the deep earth is a strategic scientific problem we must solve” is an important thought put forward by General Secretary Xi Jin-ping, and also a new requirement for geologists put forward by the country. Deep geological processes result from the combined action of the planet Earth as a carrier in the solar stellar system and its larger scale space. From the short cycle of tide between the Moon and the Earth, to the season change due to Earth-Sun interaction, to the larger scale-alternative of glacial-interglacial stages, and even a longer periodical change, all affect the Earth itself, such as expansion-contraction, sea-level change, eruptions and lull of active volcanoes, catastrophe-mineralization/accumulation of resources. The destruction and reconstruction of living environment have a profound impact on the ecological environment of our Earth home.Strategic key minerals are mostly controlled by deep geological processes such as diamond in kimberlite/lamproites/olivine basalts; uranium deposit, a new energy mineral resources, in volcanic rocks or sandstones controlled by deep faults; lithium, rubidium, cesium and niobium, tantalum, zirconium, hafnium and rare metals hosted in pegmatites derived from deep fluids; rare precious metals, gold-silver-platinum group elements-cobalt-rhenium controlled by deep fluids; and rare-earth elements are mainly produced in carbonate-alkaline complex of deep source. Most of these minerals are essential raw materials for burgeoning industries. At the same time, the deep geological process and its corresponding shallow products are the information window of understanding the core-mantle material composition. The strategic key minerals have historically driven the research of deep geological processes to geologists.
In recent years, many domestic scientific research units, institutions of higher learning, and geological exploration units for deep geological process and related key strategic minerals was carried out by geological investigation and scientific research, and a series of new progress have been made, including deep rocks as kimberlites- lamproites-olivine basalts plus others, and deep-sources minerals as diamonds, precious metals, uranium, rare earth-rare trace-rare disperse minerals and other aspects. In order to better promote the academic research and application transformation of deep geology and strategic key minerals, and serve the needs of the country, Acta Geoscientica Sinica organizes a specific issue, “Deep Geological Process and Strategic Key Minerals”, serving for experts and scholars in deep exploration and related research and exploration of strategic key minerals (diamond, uranium, rare earth-rare trace-rare disperse-precious metals). |
