地球科学发展趋势的思考——以地球动力学和超大型矿床形成机制为例

 从地球动力学和超大型矿床这两个地球科学前沿问题着手, 初步探讨了地球科学的发展趋势。地球动力学盲在解决地球形成和演化的关键性问题, 它涵盖了岩石圈板块动力学、地幔动力学、地核动力学及核-幔动力学, 地球动力来源是地球动力学研究的焦点, 它涉及了地球整体性和各圈层相互作用研究范畴。超大型矿床, 尤其是非常规超大型矿床, 是特定因素在特定条件下的耦合, 超大型矿床形成机制同样涉及了地球圈层相互作用。通过地球动力来源和超大型矿床形成机制初步探讨, 认为地球科学总的发展趋势是向着整体性和系统性方向发展, 地球单一圈层的研究已很难适应地球科学的发展, 需要从系统科学的角度去研究。

Reflections on earth science development trend: Geodynamics and formation mechanism of superlarge mineral deposits

Earth science has been profoundly transformed in the direction of system science. Grasping the development trend of earth science is helpful for understanding the general direction of earth science research. This paper inquires into the trend of earth science development, focusing on two frontier issues in earth science, geodynamics and superlarge deposits. Geodynamics is pivotal for studying earth formation and evolution, including lithospheric plate dynamics, mantle dynamics, core dynamics and core- mantle dynamics. The key to geodynamic studies is the power source of earth, involving integrity of the whole earth and interactions of earth spheres. Superlarge deposits, especially non- conventional ones, are formed with specific factors under specific conditions. The formation mechanism of superlarge deposits is also related to the interaction of earth spheres. Based on discussion of the aforementioned issues, earth science is considered to develop toward holistic and systematic orientation. Studies of a single earth sphere cannot meet the requirement of earth science development. Earth science research needs to be oriented toward systemization.
