What is a sedimentary sequence?
What is a sedimentary sequence?
Sedimentary sequences are layers of rock which are derived from weathered rocks, biogenic (= of living organisms) activity, or precipitation from solution. The Perth Basin contains very thick Mesozoic and older Permian sedimentary sequences which are the targets for drilling in the area.
What is transgression in stratigraphy?
A transgression occurs when the rate of sea level rise landward exceeds the rate of sediment input and causes an increase in accommodation, initiating the development of a transgressive surface over which the trangressive sediments of the transgressive systems tract onlap and retrograde.
What is sequence stratigraphy mostly looking at?
Sequence stratigraphy is a type of stratigraphy that deals with the description, interpretation, classification, and nomenclature of sedimentary rocks based on their stratal stacking patterns and their stratigraphic relations.
What are stratigraphic techniques?
Stratigraphy is the study of layered materials (strata) that were deposited over time. By digging from the top downward, the archaeologist can trace the buildings and objects on a site back through time using techniques of typology (i.e., the study of how types change in time).
What is sequence stratigraphy PDF?
Sequence stratigraphy is a methodology that employs stratal stacking patterns and key bounding surfaces to erect a framework allowing depositional facies to mapped and interpreted paleogeographically.
What is studied in stratigraphy?
stratigraphy, scientific discipline concerned with the description of rock successions and their interpretation in terms of a general time scale. It provides a basis for historical geology, and its principles and methods have found application in such fields as petroleum geology and archaeology.
What is the importance of stratigraphy?
Stratigraphy is they classification of different layers or layering of sedimentary deposits, and in sedimentary or layered volcanic rocks. This field is important to understanding the geological history and forms the basis for classification of rocks into distinct units that can be easily mapped.
