第四纪地质学的基本课题是研究约二百万年以来的地球发展史,特别是地壳发育史。在这里定量的时间表是非常重要的。近十余年来,第四纪地质学取得了长足进展,其中重要的一个方面,就是日益广泛地应用地质年代学的资料来探讨不同地区第四纪地质事件及古人类发展的历史规律。 建立和发展第四纪地质年代学不仅对于认识“近代”地球上有机界和无机界的演化过程和演化速率,预测其未来发展趋势,从而合理地利用自然资源、保护自然环境、改造不利的自然条件等方面有长远的意义,而且对于当前生产建设也有重要的现实意义。开 The basic topic of quaternary geology is to study the history of the earth about two million years ago, especially the history of crustal development. The quantitative timetable here is very important. Quaternary geology has made considerable strides over the past decade or so. An important aspect of this is the increasingly extensive application of geological chronology to discuss the historical laws of Quaternary geological events and ancient human development in different regions. The establishment and development of quaternary geochronology not only for predicting the future development trend of understanding the “modern” evolution of the organic and inorganic boundaries of the earth, but also for the rational use of natural resources, the protection of the natural environment and the transformation of unfavorable nature Conditions and other aspects of long-term significance, but also for the current production and construction also has important practical significance. open
