From allo- + stratigraphy.
Noun[edit]
allostratigraphy (usually uncountable, plural allostratigraphies)
- (geology) The study and classification of rock strata by their bounding surfaces, such as unconformities and other types of uncomformable contacts that create discontinuities in the rock record.
- Coordinate terms: biostratigraphy, chemostratigraphy, chronostratigraphy, climatostratigraphy, cyclostratigraphy, electrostratigraphy, lithostratigraphy, magnetostratigraphy, tectonostratigraphy

- The only example we know is the study of the allostratigraphy of Quaternary terrace deposits in the Polish Carpathians by Zuchiewicz (1988), in which individual mapping units included gravels, solifluction deposits and loess.

- North (1996) believed that allostratigraphy is in effect an extension of Miall's architectural element analysis and is a more natural method of subdividing sediments for interpretative purposes than the conventional lithostratigraphy.

- The modern North American tendency is to prefer allostratigraphy to lithostratigraphy in defining formal units (NACSN, 1983). Allostratigraphy uses the bounding limits of a sediment interval to define it, the contrary to lithostratigraphy which defines what the interval is.
