1. Lithostratigraphy. The element of stratigraphy that deals with the description and nomenclature of the rocks of the Earth based on their lithology and their stratigraphic relations. 2. Lithostratigraphic classification. The organization of rock bodies into units on the basis of their lithologic properties and their stratigraphic relations.A. General. Stratigraphic classification encompasses all rocks of the crust of the Earth. Rocks have many tangible and measurable properties and may be classified according to any of them. Rocks may also be classified by their time of origin or interpreted attributes, such as environment or genesis. The stratigraphic position of change for any ...…
