Superposition is a relative age dating principle which states
Stratigraphy is a branch of geology that studies rock strata with an emphasis on distribution, deposition, age and evidence of past life.
Nicolas Steno, William Smith, Georges Cuvier, Alexandre Brongniart, and James Hutton developed the basic rules for the science of stratigraphy.
Relative time places events or formations in order based on their position within the rock record relative to one another using six principles of relative dating.
Relative time can not determine the actual year a material was deposited or how long deposition lasted; it simply tell us which events came first.
We'll even visit the Grand Canyon to solve the mystery of the Great Unconformity!
Steno recognized that fossils represent organisms that became buried in sediment, which later turned into rock.
Other examples of non vertical superposition would be modifications to standing structures such as the creation of new doors and windows in a wall.
Superposition in archaeology requires a degree of interpretation to correctly identify chronological sequences and in this sense superposition in archaeology is more dynamic and multi-dimensional.
The law of superposition is an axiom that forms one of the bases of the sciences of geology, archaeology, and other fields dealing with geological stratigraphy.
In its plainest form, it states that in undeformed stratigraphic sequences, the oldest strata will be at the bottom of the sequence.
Search for superposition is a relative age dating principle which states:
The most obvious feature of sedimentary rock is its layering.
