第四纪是地球发展史的最新一章,地壳发育的最新一幕,第四纪沉积物,作为一定地质过程在特定地质环境中形成的产物,在它形成以后又受着各种自然因素和人类活动的作用和改造,留下了许多环境历史和环境变化的遗迹,记录着这许多自然过程。第四纪沉积物的研究对于恢复和重建第四纪地质时期的地球发展史可提供丰富的科学史料,同时对于探索前第四纪地质历史时期地壳演化规律,阐明某些古老的地质作用和地质规律具有普遍意义,也为将来自然变动的
Quaternary is the latest chapter in the history of the earth and the latest episode of crustal development. Quaternary sediments, as a product of a certain geological process formed in a specific geological environment, are subject to various natural factors and human beings The role and transformation of the activities left many remnants of environmental history and environmental change and recorded many of these natural processes. The study of Quaternary sediments can provide a wealth of scientific historical data for the restoration and reconstruction of the Earth’s history during the Quaternary geological period. At the same time, it is of great significance to explore the laws of the evolution of the crust before the Quaternary geological history and clarify some ancient geological features and geology Law has universal significance, but also for future natural changes
