Stratigraphic data is a required component in archaeological archives, but there is a growing problem for digital data archives, where stratigraphic data are often only held on paper or as scanned image copies (PDFs) of matrix diagrams. This means that they cannot be easily re-used in further analysis.
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'.
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 ...
On sites with little stratigraphic depth, a pre-excavation multi-context plan is sometimes made of all visible features before any excavation is carried out. This helps in planning strategy since problems of stratigraphy on rural sites are minimal as features often cut into the natural minimizing issues of inter-cutting features. Conversely ...
Components of the archaeological record include: artifacts, built structures, human impact on the environment, garbage, stratigraphy, mortuary practices, plant remains, or animal remains. Artifacts from the archaeological record are usually found in the ground, and once dug up, archaeologists put data such as photographs and exact location of ...
The principles of lithostratigraphy were first established by the Danish naturalist, Nicolas Steno, in his 1669 Dissertationis prodromus. [1] A lithostratigraphic unit conforms to the law of superposition, which in its modern form states that in any succession of strata, not disturbed or overturned since deposition, younger rocks lies above older rocks. [2]
During the 17th century, Nicolas Steno was the first to observe and propose a number of basic principles of historical geology, including three key stratigraphic principles: the law of superposition, the principle of original horizontality, and the principle of lateral continuity.
It has become a popular system of recording and planning being used in many countries in Europe and in Lebanon, it is especially suited to the complexities of deep, typically urban, archaeology. Each excavated context is given a unique "context number" and is recorded by type on a context sheet and perhaps being drawn on a plan and/or a section ...
