Stratigraphic location
WebThe Quaternary of the British Isles contains a diverse variety of glaciogenic sediments, non-glaciogenic terrestrial and marine deposits scattered across large parts of the British Isles. These can be broadly grouped into major units, and can be divided at a much finer scale into chronostratigraphic and lithostratigraphic units. WebStratigraphic unit A body of rock established as a distinct entity in the classification of the rocks, based on any of the properties or attributes or combinations thereof that rocks possess. Stratigraphic units based on one property will not necessarily coincide with those based on another. Stratigraphic terminology

Stratigraphy is a branch of geology concerned with the study of rock layers (strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks.
