"Stratigraphy is a branch of geology concerned with the study of rock layers (strata) and layering (stratification)."
The study of rock layers and layering, which is important in determining the relative age of fossils and the sequence of geological events that occurred at a given site.
Geological Time Scale: The study and understanding of the timeline of Earth's formation, including the evolution of life and geological events.
Sedimentary Rocks: The types, classification, characteristics, and formation of sedimentary rocks.
Fossils: The preservation, recognition, and identification of fossils, including their use in stratigraphy.
Stratigraphic Principles: The fundamental principles that are used to establish relative age relationships between rock layers.
Stratigraphic Correlation: The techniques and methods used to compare and match rock layers from different locations.
Biostratigraphy: The use of fossils to establish the ages and sequences of rock layers.
Lithostratigraphy: The use of rock types and characteristics to establish the ages and sequences of rock layers.
Chronostratigraphy: The study of the relative timing of geological events and the development of the geological time scale.
Paleoenvironments: The reconstruction of past environments based on the information obtained from the rock and fossil record.
Paleoecology: The study of past ecosystems, including the interactions between organisms and their environments.
Paleoceanography: The study of past oceans, including changes in sea level, temperature, and chemistry.
Taphonomy: The study of the process of fossilization and the effects of decay and preservation on the fossil record.
Microfossils: The study of microscopic fossils, including their use in paleoenvironmental and biostratigraphic studies.
Global Change: The study of how the Earth's climate and environment have changed over time, including the impact of human activity.
Sequence Stratigraphy: The study of depositional sequences and cycles, including their use in understanding changes in sea level and climate.
Basin Analysis: The study of the evolution of sedimentary basins, including their formation and filling, and the relationship of the basin to the overall tectonic setting.
Geochronology: The study of the absolute ages of rocks and events, including the techniques used to date rocks and the development of the geologic time scale.
Isotope Geochemistry: The study of the isotopic composition of rocks and minerals, including their use in dating, tracing, and understanding geologic processes.
Geophysics: The study of the physical properties of rocks and the Earth's subsurface, including seismic imaging and gravity and magnetic surveys.
Paleomagnetism: The study of the Earth's magnetic field recorded in rocks, including its use in understanding plate tectonics and paleogeography.
Lithostratigraphy: This type of stratigraphy involves the study of rock layers and formations, and their physical and chemical properties.
Biostratigraphy: A subdomain of stratigraphy that involves the study of the fossil record of plants and animals to determine relative ages of rock layers.
Chronostratigraphy: Similar to Biostratigraphy, it involves the use of fossils to determine the relative ages of rocks, but it especially focuses on establishing the age of geological time units with reference to the present.
Magnetostratigraphy: A variety of chronostratigraphy that focuses on the study of magnetic properties of rocks to determine their age.
Chemostratigraphy: Stratigraphy that examines the composition of rocks to determine the chronology of geologic time.
Seismic Stratigraphy: A specialized form of stratigraphy that involves the study of seismic reflection data of rock layers beneath the earth's surface.
Cyclostratigraphy: Stratigraphy based on the cyclic nature of sedimentary rock and the characteristics found therein.
Event Straticraphy: This stratigraphic approach seeks to identify short-term geologic events that have happened in the past.
Tectonostratigraphy: This type of stratigraphy focuses on the study of rock that has been subjected to tectonic activity, including faulting and folding.
Sequence stratigraphy: Stratigraphy that utilizes the fundamental concepts of sedimentary sequences to interpret the age, nature and depositional environment of rock layers.
