eventstratigrafi
Eventstratigraphy is a branch of stratigraphy that focuses on the recognition and correlation of sedimentary layers based on unconformities and discontinuities. These unconformities represent periods of missing time due to erosion or non-deposition, and are often caused by significant geological events. By identifying and dating these event surfaces, geologists can divide rock sequences into distinct packages of strata.
The fundamental principle of eventstratigraphy is that major geological events, such as sea-level changes, volcanic eruptions,
Key to eventstratigraphy is the concept of the "event horizon," which is the boundary surface representing the
