Stratigraphy is the science of knowledge that studies the variations in the successively layered rock structured along with the compositions. This field of science is important to study geological history, which forms the basis for the classification of rocks into distinct units. Thus stratigraphy serves as an important key in order to understand and analyze the complex structure of the bedrocks with respect to space and time.
Stratigraphy is also subdivided into various fields such as Lithostratigraphy, Biostratigraphy, Chronological Stratigraphy, and Magnetostratigraphy.
