  2. Perspective geological correlation - Wikipedia

    en.wikipedia.org/wiki/Perspective_geological...

    Geological perspective correlation is a theory in geology describing geometrical regularities in the layering of sediments. Seventy percent of the Earth's surface are occupied by sedimentary basins [1] – volumes consisted of sediments accumulated during million years, and alternated by long interruptions in sedimentation (hiatuses).

  3. Biostratigraphy - Wikipedia

    en.wikipedia.org/wiki/Biostratigraphy

    Biostratigraphy is the branch of stratigraphy which focuses on correlating and assigning relative ages of rock strata by using the fossil assemblages contained within them. [1] The primary objective of biostratigraphy is correlation, demonstrating that a particular horizon in one geological section represents the same period of time as another ...

  4. Lithostratigraphy - Wikipedia

    en.wikipedia.org/wiki/Lithostratigraphy

    Lithostratigraphy is a sub-discipline of stratigraphy, the geological science associated with the study of strata or rock layers. Major focuses include geochronology, comparative geology, and petrology. In general, strata are primarily igneous or sedimentary relating to how the rock was formed.

  5. Relative dating - Wikipedia

    en.wikipedia.org/wiki/Relative_dating

    Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age (i.e., estimated age). In geology, rock or superficial deposits, fossils and lithologies can be used to correlate one stratigraphic column with another.

  6. Geochronology - Wikipedia

    en.wikipedia.org/wiki/Geochronology

    Geochronology. An artistic depiction of the major events in the history of Earth. Geochronology is the science of determining the age of rocks, fossils, and sediments using signatures inherent in the rocks themselves. Absolute geochronology can be accomplished through radioactive isotopes, whereas relative geochronology is provided by tools ...

  7. Magnetostratigraphy - Wikipedia

    en.wikipedia.org/wiki/Magnetostratigraphy

    Magnetostratigraphy is a geophysical correlation technique used to date sedimentary and volcanic sequences. The method works by collecting oriented samples at measured intervals throughout the section. The samples are analyzed to determine their characteristic remanent magnetization (ChRM), that is, the polarity of Earth's magnetic field at the ...

  8. Stratigraphy and Geological Correlation - Wikipedia

    en.wikipedia.org/wiki/Stratigraphy_and...

    Stratigraphy and Geological Correlation. Stratigr. Geol. Correl. Stratigraphy and Geological Correlation is a bimonthly peer-reviewed scientific journal covering fundamental and applied aspects of stratigraphy. It was established in 1993 and is published by Springer Science+Business Media on behalf of MAIK Nauka/Interperiodica .

  9. Stratigraphic unit - Wikipedia

    en.wikipedia.org/wiki/Stratigraphic_unit

    Stratigraphic unit. A stratigraphic unit is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features (facies) that characterize it. Units must be mappable and distinct from one another, but the contact need ...
