Sequence Stratigraphy has recently been added as a branch of geology and its purpose is to connect pre-historic sea level changes to sedimentary deposits. It is called 'sequence' stratigraphy because it mentions cyclic sedimentary deposits.
Sedimentary deposits are significant because they include a lot of important minerals for industries such as petroleum, gas, iron, aluminum and coal. The deposits are also used to get gravel, limestone, chalk, sand, clay, and slate.
'Stratigraphy' literally means the study of rock strata and their relationship to the geological time scale.
It also talks about the transferring and age sediments and gives us a good idea about how we get sediments.
This is important because sea levels constantly changing over time and are rising and if they continue to do so it can be very dangerous to several cities and corporations that depend on the sea.
