Sequence stratigraphy is a branch of geology, specifically a branch of stratigraphy, that attempts to discern and understand historic geology through time by subdividing and linking sedimentary deposits into unconformity bounded units on a variety of scales.
In sequence stratigraphy, a sub discipline of geology, type 1 sequences and type 2 sequences are special sequences that are defined by having distinct types of sequence boundaries. In modern literature, the distinction in type 1 sequences and type 2 sequences was abandoned. [1] [2]
Wheeler's work in the 1950 and 1960s was pivotal in the later development of sequence stratigraphy, which is still used today, for example by petroleum industry geologists. [3] His 1964 paper, Baselevel, Lithosphere Surface, and Time-Stratigraphy [ 4 ] evolved the concept of base level to emphasize the continuous spatial and temporal nature of ...
It describes the sequence of layers in the basin as consisted of stratigraphic units. Units are defined on the basis of their lithology and have no clear definition. [ 3 ] Geological Perspective Correlation (GPC) is a theory that divided the geological cross-section in units according strong mathematical rule: all borders of layers in this unit ...
Stratigraphy is a branch of geology concerned with the study of rock layers and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks . Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy ...
Animation showing interpretive grouping and phasing on matrix diagram. The Harris matrix is a tool used to depict the temporal succession of archaeological contexts and thus the sequence of depositions and surfaces on a 'dry land' archaeological site, otherwise called a 'stratigraphic sequence'.
A general theory of basin-scale deposition has been formalized under the name of sequence stratigraphy. [ 3 ] Some cyclothems may have formed as a result of marine regressions and transgressions related to growth and decay of ice sheets , respectively, as the Carboniferous was a time of widespread glaciation in the southern hemisphere. [ 4 ]
Sequence stratigraphy, the study of sea level change through the examination of sedimentary deposits, was developed from the centuries-old controversy over the origin of cyclic sedimentation and the relative importance of eustatic and tectonic factors on sea level change.
