Stratigraphy

(see articles on Biostratigraphy, Chronostratigraphy, Lithostratigraphy, and Magnetostratigraphy.

Stratigraphy (Latin ‘stratum’ + Greek ‘graphia’), is the interdisciplinary science field that describes all rock bodies that form the Earth's crust and the manner in which they are organised into distinctive, units that are then mapped. These ‘stratigraphic maps are based on the inherent properties or attributes of rock bodies in order to establish their distribution and relationship in space and their succession in time. The distinctions and the maps are used to interpret geologic history.
