Baisn Analysis – So what’s with Sequence Stratigraphy?

Posted in Geology by akamal on May 16, 2009

Q – The main question always comes up first, what is sequence stratigraphy?

A – Well, I can tell you that it actually deals a lot with the examination and interpretation of sedimentary strata, with several implications as below:

  • Based on Vertical and lateral facies relationship. [KW]:- Facies
  • Subdivision of sedimentary basin fill into Genetic Packages, bounded by time significant surfaces. [KW]:- Genetic Packages
  • Units and bounding surfaces controlled by changes in Relative Sea Level and Sediment Influx. [KW]:- Controls, Sea Level, Sediment Influx
  • Provides a time framework for the correlation, mapping and preiction of stratigraphy from basin to field scale. [KW]:- Time Framework

Q – Advantages of Seq Strat includes among all:

A –

  • Provide a process based interpretation. [KW]:- Process based interpretation
  • Predictive (Spatial and temporal relationship of facies). [KW]:- Well, Predictive
  • Applies to seismic, log, core and outcrop. [KW]:- Applies to data
  • Common language between discipline. [KW]:-language

Q – Difference between Lithostratigraphic Correlation and Seq Strat Correlation:

A –

  • Lithostratigraphic correclation differentiate between lithology of rock types. The latter deals with changes dealing with sea level.

    Keep in mind that this code will probably be replaced when you update your Word –
    Press installation, and then you will have to repeat the action again later.
    If you have never edited code, don’t worry, this article will walk you through the steps.
