Sequence Stratigraphy authoritative online encyclopedia from SEPM, a scientific society whose publications have been central to defining sequence stratigraphy. An Online Guide to Sequence Stratigraphy by the University of Georgia's Stratigraphy Lab. USC's Sequence Stratigraphy Web a fairly extensive online education resource; A chart of sea ...
The definition of a type 1 and type 2 sequence was first introduced by Vail et al. (1984). [4] Since they were hard to recognize, they were redefined in 1990 by Van Wagoner et al.. However even with this new definition, type 2 sequence boundaries were hard to recognize in the field due to their lack of subaerial exposure.
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'. The matrix reflects the relative position and stratigraphic contacts of
In a more rigorous and general way, a sequence is defined as a "relatively conformable [...], genetically related succession of strata bounded by unconformities or their correlative surfaces" [ 2 ] Special cases and related concepts
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 ...
Also, the terms Archaeological sequence and Archaeological stratigraphy are closely related and somewhat interchangeable. These colloquial uses of the term are normal in conversation but: The term 'sequence' when narrowly defined, and used in a serious piece of writing, refers to the stratigraphy of a given site or any discrete part of the ...
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.
Sedimentology is closely linked to stratigraphy, the study of the physical and temporal relationships between rock layers or strata. The premise that the processes affecting the earth today are the same as in the past is the basis for determining how sedimentary features in the rock record were formed.
