(2014年5月17日)前言党的“十八大”提出了把生态文明建设纳入中国特色社会主义“五位一体”的基本布局,对地质工作提出了新的更高要求。地层是地球发展历史过程中分布最广、时代跨度最大、意义最为重大的地质记录。地层学是地质科学奠基性的学科,其主要任务是研究构成地壳的所有层状或似层状岩石体的特征和属性,据此将它们划分为不同类型和级别的单位,并建立它们之间的时间顺序和空间关系。地层学经历了初创、统一地层、多重地层划分等阶段,目前正朝着建立全球标准年代地层系统和从区域地层对比逐渐扩展到全球地层对比的方向发展。地层学在地球科学体系的建立与发展方
(May 17, 2014) Foreword The “18th National Congress of the Party” put forward the basic layout of integrating ecological civilization into the “Five in One” with Chinese characteristics and put forward new and higher requirements for geological work . Stratigraphy is the most widely distributed geological record with the largest span and the most significant significance in the history of the Earth’s development. Stratigraphy is a ground-breaking discipline in geoscience. Its main task is to study the characteristics and attributes of all stratiform or laminar-like rock bodies that make up the crust, divide them into units of different types and levels, and establish relationships between them The chronological and spatial relations. Stratigraphy has undergone a series of stages such as initial formation, unified formation and multiple stratigraphic division. Currently, stratigraphy is moving toward the establishment of a global standard age stratigraphic system and the gradual expansion from regional stratigraphic correlation to global stratigraphic contrast.
