| 矿物记录了地球化学过程、地球的形成与演化，乃至生命起源等重要过程与重大事件的关键信息。矿物多样性演化与地球的演化进程息息相关。本文利用最新的矿物学数据库，对新矿物的发现进行空间分 析，对比各大陆在新矿物发现领域的异同点，发现以美国和俄罗斯为代表的欧美国家在新矿物发现领域 中位于领先地位。通过对所发现矿物进行时间序列分析，与现有锆石、变质岩、大火成岩省等地质记录进 行对比，发现矿物多样性演化具有明显的 600~800 Ma的长周期，可能受超大陆演化主导；在超大陆聚合 期，矿物多样性增加；而超大陆稳定和离散期，矿物多样性明显减少。此外，各大陆的矿物多样性演化具 有较为一致的节律，但也受自身构造-岩浆-沉积等演化过程影响。研究结果为认识超大陆与矿物多样性 协同演化提供新的证据。 |

| Minerals record the key information of important processes and major events such as geochemicalprocesses, understanding the formation and evolution of the earth, and even the origin of life. The evolution of min.eral diversity is closely related to the evolution of the earth. Based on the latest mineralogical database, in this papera spatial analysis was conducted to reveal the similarities and differences of different continents in the field of newmineral discovery. It is found that the United States and Russia are in the leading position in the field of new min.eral discovery. Through time series analysis of the discovered minerals and comparison with the existing geologicalrecords such as zircon, metamorphic rocks and large igneous provinces, it is found that the evolution of mineral di. versity has a long period of 600-800 Ma, which may be dominated by the evolution of supercontinents. Moreover,during the assembly of supercontinents, mineral diversity increased. However, the mineral diversity decreased sig.nificantly during the stable and breakup periods of the supercontinent. In addition, the evolution of mineral diversityin each continent has a relatively consistent rhythm, but it is also influenced by its own evolution processes such asstructure-magma-deposition. The results provide new evidence for understanding the co-evolution of superconti.nent and mineral diversity. |
