| 摘 要： | 前寒武纪地质学是现代地球科学中最活跃的学科之一。我国前寒武纪地质研究有着良好的条件和优良的传统，前寒武纪岩石在中国大陆上有广泛的分布，保存了从3800Ma到543Ma较完整的岩石、地层和生物形成与演化的历史记录，并蕴藏了丰富的矿产资源。简要回顾了近百年来我国前寒武纪研究的历史，取得的丰硕成果及巨大进展。概述了中国前寒武纪时期的大陆，特别是太古宙华北克拉通地壳演化的特殊性和复杂性，与世界其他地区的克拉通进行了对比。指出前寒武纪地质学在研究地球科学中仍然处于重要的位置，尤其是研究前寒武纪超大陆汇聚与裂解及前寒武纪成矿区带的划分已成为当今世界研究的热点。在此基础上，提出了对我国21世纪前寒武纪地质学的工作设想和展望。

| Abstract: | Precambrian geology is one of the most active branches of the modern geosciences and the Precambrian rocks are well developed and widespread in the mainland of China, in which the organic origin and evolution were recorded from 3 800 to 543 MaB. P. , and rich mineral resources are contained. The history of nearly a hundred years of the Precambrian studies, their plentiful results and great advances are briefly reviewed in this paper. The particularity and complexity of the craton crustal evolution of the mainland of China during the Precambrian, especilly North China during Archaeozoic time are briefly discussed. A correlation with the cratons of the other regions in the world is made, pointing out the importance of the Precambrian geology in the study of the geosciences, especially the supercontinental convergence and cracking and the division of the metallogenic province, which have become the hot points of the studies all over the world. Based on these, an imagination and prospect for work on the Precambrian geology during the 21st century is proposed. |
