compromise section
CATEGORY: term
DEFINITION: A method of drawing sections which may or may not define interfaces or label of the units of stratification appearing in sections.
cross section
SYNONYMS OR RELATED TERMS: cross-section
CATEGORY: structure
DEFINITION: In masony, the configuration of a wall through its thickness. It can be compound (combination of single stone and double stone), compound with core (areas separated by rubble core), double bonded (double stone with overlap in interior), double stone with core (two stones wide with rubble core but no overlap in interior), double stone (two adjacent stones wide, no overlap), or single stone.
cross-sectional trenches
SYNONYMS OR RELATED TERMS: slot trenches
CATEGORY: technique
DEFINITION: A type of excavation in which a set of superimposed strata are cut across by deep trenches that expose the history of deposition.
cumulative section
CATEGORY: technique
DEFINITION: A record of a stratigraphic sequence in which each layer is drawn and then removed, rather than left standing as a reference and drawn in its entirety at the end of the excavation.
lateral section
CATEGORY: artifact
DEFINITION: A cross section in which the cut is made perpendicular to the base line of the artifact drawing and the outline of the section is oriented like a profile view but in horizontal alignment with the points through which the cut was made
realistic section
CATEGORY: term
DEFINITION: A means of drawing sections to give an artistic impression of a soil profile, in which no interfacial lines or layer numbers appear.
section
SYNONYMS OR RELATED TERMS: sectioning, section drawing
CATEGORY: technique
DEFINITION: In excavation, the exposing of a deposit vertically to reveal the stratigraphy of a site or details of a particular feature. A balk is left across a feature or a complex of features, or a hole is cut out of a feature and trimmed to a flat face in which layers and changes in soil color may be examined. Sections automatically occur when the grid method of excavation is used, on all four sides of each trench. The term is also applied to the drawing of the vertical record of the stratification of a site or feature. A section drawing is a two-dimensional rendering, at a constant scale, depicting archaeological data and matrix as seen in the wall of an excavation. Advocates of open-area excavation prefer not to have standing sections on the site; instead of drawing sections after the whole area has been excavated, they record the profile of each deposit as it is excavated and construct what are known as 'cumulative' or 'running sections'.
standing section
CATEGORY: technique; feature
DEFINITION: A section on the face of a balk which is left standing during the course of an excavation.
stratigraphic section
CATEGORY: technique
DEFINITION: The excavation of trenches and squares across manmade layers to expose a cross-section of the deposits on an archaeological site and to reveal the sequence and methods of construction.
stylized section
CATEGORY: term
DEFINITION: A section showing all the interfaces and layers of a soil profile, with the units of stratification numbered.
thin sectioning
SYNONYMS OR RELATED TERMS: thin-section analysis; thin-section; thin section
CATEGORY: technique
DEFINITION: The removal of a very thin slice of material from an object, typically pottery or stone, for the purpose of examination under the petrological microscope. The sample chip may have to be ground down to 0.03 mm before mounting on a slide. The sample must be thin enough to determine the details of crystals and other structures. It is then possible to identify the source of the raw materials from which the object was made. The technique is also applied to soil, bone, and dental tissues.
transverse section
CATEGORY: artifact
DEFINITION: A cross section where the cut is made parallel to the base line of the artifact drawing and the outline of the section keeps the front surface at the top
