地层学(英語:stratigraphy[1]地质学的一个分支,是地质学的基础学科,是在19世纪初发展起来的一个学科,最早用于研究沉积岩火山喷出的层序。现在的研究包括地层的时代和地理分布,地层的分类,各种岩石之间的关系等。地层学根据主要研究对象不同可以分为岩石地层学、生物地层学和年代地层学。

岩石地层学

是最主要的分支,研究不同地层的岩石特点,地层倾斜对沉积的影响,地层的化学成分等

生物地层学

主要研究各个地层中的生物化石,确定个地层的年代,对生物进化学说起到相当大的证实作用。

年代地层学

主要用于考古断代,不同地层的考古发现可以帮助确定其年代。

地层学的研究还对寻找沉积矿床起到指导作用。
