现代地球科学的特征是地质学、地球物理学与地球化学相结合,大陆与海洋相结合,地壳与地幔相结合,时间追溯到远古,空间扩展到星际。基础地质中地质史的研究最能体现这些特点。它既是各地质分支学科综合探讨所得的总体认识,又为各学科提供时空格架和轮廓背景。地质史研究有三个方面的标志:一是地质时代表的建立,二是构造阶段的厘订,三是构造单元的划分,其内容随着学科的向前发展而不断更新。地质时代表的建立从以生物演化为主逐步趋向于生物演化、同位素地质年龄和古地磁极向转变三者并重。古地磁极向研究已从晚古生代扩展到早古生代和前寒武纪,将来在时代轮廓划分和详细
Modern geosciences are characterized by the combination of geology, geophysics and geochemistry, the combination of the mainland and the oceans, the combination of the crust and the mantle, dating back to the ancient times and expanding into the interstellar space. The study of geological history in basic geology can best reflect these characteristics. It is not only an overall understanding of the comprehensive exploration of various geological disciplines, but also provides a time-space frame and outline background for various disciplines. There are three aspects of geological history research signs: First, the establishment of geological representatives, the second is the construction phase of the set, the third is the division of structural units, its content with the development of disciplines and constantly updated. The establishment of geological representatives from the evolution of the main biological gradually tend to evolution, isotope geology age and paleomagnetic polar transformation of the three equal. The study of paleomagnetic polarity has been extended from the Late Paleozoic to the Early Paleozoic and Precambrian. In the future,
