“What is the branch of geology concerned with rock layers and historical layering?”

Rocks layers and layering have so many different aspects about them. Whether it’s their lithology (physical properties) or how their physical relationship to each other explains their historical evolution, there’s something to explore. There is so much information about these rocks that there’s a whole field, Stratigraphy, dedicated to understanding this. Stratigraphy is a subset of geology that analyzes rock layers and their historical layering.
