International Commission on Stratigraphy
The Abridged Version of the International Stratigraphic Guide, like the Guide itself, was developed to promote international agreement on principles of stratigraphic classification and to develop an internationally acceptable stratigraphic terminology and rules of procedure in the interest of improved accuracy and precision in international ...
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 clas-sified by their time of origin or interpreted attributes, such as envi-ronment or genesis.

pedostratigraphic classification. In general, a geosol is a buried and lateral soil profile range that is characterized by several important or dominant soil types, which are recognized and described in stratigraphic context. The upper boundary of a pedostratigraphic unit is the top of the uppermost pedologic horizon formed by pedogenesis in a

Stratigraphy, from Latin stratum + Greek graphia, is the description of all rock bodies forming the Earth’s crust and their organization into distinctive, useful, mappable units based on their inherent properties or attributes in order to establish their distribution and relationship in space and their succession in time, and to interpret geolog...
Concepts of stratigraphical classification and terminology
The new threefold stratigraphical classification has been worked out partly by the American Commission on Stratigraphic Nomenclature, established in 1946, and partly by the Subcommission on Stratigraphic Terminology established in 1952 as a branch of the International Commission on Stratigraphy.
