WebThe geologic time scale is the stratigraphic history of the Earth.Stratigraphy, also called chronostratigraphy is the ordering and analysis of the layers of the Earth (also called strata) based chronological dating techniques and the layers' positions relative to each other.Geologic time begins approximately 4.6 billion years ago, shortly after when the … Stratigraphy is a branch of geology concerned with the study of rock layers (strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks. Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy (stratigraphy by age).
