ABSTRACT
This chapter examines the correlation and the procedures involved in Quaternary stratigraphy. Stratigraphy is the study of the chronological order of rocks and sediments, and also of the sequence of events reflected within them. The fundamental building blocks are units of geological strata that can be identified on the basis of visible attributes, such as colour, grain-size variations or structural elements. The chapter explains that biostratigraphic classification organizes rock strata into units based on the variety and abundance of fossils. Morphostratigraphy is rarely discussed in stratigraphic codes, yet is an essential stratigraphic method in Quaternary science. The chapter explains that oxygen isotope profiles from deep-ocean cores can be divided into marine isotope stages (MIS), and these stages and sub-stages are fundamental units in Quaternary stratigraphy. It also explains chronostratigraphy is the classification of the stratigraphic record in terms of time.
