A diagram representing a vertical sequence of rock layers, showing their relative positions, rock types, and often fossils, used as a standard reference.
It is generally uncountable when referring to the science (e.g., 'She specialised in stratigraphy'). It can be used countably when referring to the specific layering of a place (e.g., 'The two sites have different stratigraphies').
