      Principles of Stratigraphy 1. Stratigraphy is the study of temporal relationships in sedimentary rock bodies and reflects changes in the balance between rates at which space is produced and filled. Stratigraphy can be considered the history of past geological events and adds the dimension of time to sedimentology. The spatial and stratigraphic distribution of water in oil shale of the Eocene Green River Formation in the Piceance Basin of northwestern Colorado was studied in detail using some , Fischer assay analyses in the U.S. Geological Survey oil-shale database. The oil-shale section was subdivided into 17 roughly time-stratigraphic intervals, and the distribution of water in each interval was. stratigraphic correlation Geologic study concerned with establishing geochronological relationships between different areas, based on geologic investigations of many local successions.

The Witwatersrand Basin is a largely underground geological formation which surfaces in the Witwatersrand, South Africa. It holds the world's largest known gold reserves and has produced over billion ounces (o Correlation of the Godwan Formation based on stratigraphic trends in the Witwatersrand Basin book tons), which represents about 50% of all the gold Country: South Africa.

Other articles where Stratigraphic correlation is discussed: geology: Paleontology: and on different continents, involves stratigraphic correlation from place to place. Although correlation of strata over modest distances often can be accomplished by tracing particular beds from place to place, correlation over long distances and over the oceans almost invariably involves comparison of fossils.

At the start of an interpretation of sequence stratigraphy using well logs one must first identify the predominant of sequence stratigraphic MOST important of these surfaces, and the FIRST that should be identified when using logs, are maximum flooding surfaces (mfs) and transgressive surfaces (TS).
