Cut (archaeology)
In archaeology and archaeological stratification, a cut or truncation is a context that represents a moment in time when other archaeological deposits were removed for the creation of some feature, such as a ditch or pit. In layman's terms, a cut can be thought of as a hole that was dug in the past, though cut also applies to other parts of the archaeological record such as horizontal truncations like terraced ground. A cut context is sometimes referred to as a "negative context", as opposed to a "positive context". The term denotes that a cut has removed material from the archaeological record or natural at the time of its creation, as opposed to a positive context, which adds material to the archaeological record. A cut has zero thickness and no material properties of its own and is defined by the limits of other contexts. Cuts are seen in the record by virtue of the difference between the material it was cut through and the material that back-fills it. This difference is seen a ...

Single Context Recording
Single context recording was initially developed by Ed Harris and Patrick Ottaway in 1976, from a suggestion by Laurence Keen. It was further developed by the Department of Urban Archaeology (Museum of London) from where it was then exported, in the mid-1980s by Pete Clarke to the Scottish Urban Archaeological Trust and Nick Pearson to the York Archaeological Trust. 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. Depending on time constraints and importance contexts may also be photographed, but in this case a grouping of contexts and their associations are the purpose of the photography. Finds from each context are bagged and labelled with their context number and site code for later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relationship (archaeology)
An archaeological relationship is the position in space and by implication, in time, of an object or context with respect to another. This is determined, not by linear measurement but by determining the sequence of their deposition – which arrived before the other. The key to this is stratigraphy. Stratigraphic relationships Archaeological material would, to a very large extent, have been called rubbish when it was left on the site. It tends to accumulate in events. ''A gardener swept a pile of soil into a corner, laid a gravel path or planted a bush in a hole. A builder built a wall and back-filled the trench. Years later, someone built a pig sty onto it and drained the pig sty into the nettle patch. Later still, the original wall blew over and so on.'' Each event, which may have taken a short or long time to accomplish, leaves a context, a deposit of material, on the site. This deposit and its relationship to earlier contexts may show up in section or in plan when viewed fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harris Matrix
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 observable stratigraphic units, or contexts. The Matrix was developed in 1973 in Winchester, England, by Dr. Edward C. Harris. The concept of creating seriation diagrams of archaeological strata based on the physical relationship between strata had had some currency in Winchester and other urban centres in England prior to Harris's formalisation. One of the results of Harris's work, however, was the realisation that sites had to be excavated stratigraphically, in the reverse order to that in which they were created, without the use of arbitrary measures of stratification such as spits or . In his ''Principles of archaeological stratigraphy'' Harris first proposed the need for each un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cut (earthmoving)
In civil engineering, a cut or cutting is where soil or rock from a relative rise along a route is removed. The term is also used in river management to speed a waterway's flow by short-cutting a meander. Cuts are typically used in road, rail, and canal construction to reduce the length and grade of a route. Cut and fill construction uses the spoils from cuts to fill in defiles to cost-effectively create relatively straight routes at steady grades. Cuts are used as alternatives to indirect routes, embankments, or viaducts. They also have the advantage of comparatively lower noise pollution than elevated or at-grade solutions. History The term ''cutting'' appears in the 19th century literature to designate rock cuts developed to moderate grades of railway lines. ''Railway Age's Comprehensive Railroad Dictionary'' defines a cut as "a passage cut for the roadway through an obstacle of rock or dirt." Creation Cuts can be created by multiple passes of a shovel, grader, scrap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeological Plan
In archaeological excavation, a plan is a drawn record of features and artifacts in the horizontal plane. Overview Archaeological plan can either take the form of * a "multi context" plan, which is drawn with many contexts on it to show relationships between these features as part of some phase, or * alternatively a single context plan with a single feature is drawn . Excavated features are drawn in three dimensions with the help of drawing conventions such as hachures. Single context planning developed by the Museum of London has become the professional norm. The basic advantage of single context planning is context plans draw on "transparent perma-trace paper" can be overlaid for re-interpretation at a later date. ''Multi-context Plans'' as opposed to single context plans can be made of complete sites, trenches or individual features. In the United Kingdom, the scale of the plans is usually 1:20. They are linked to the site recording system by the inclusion of known g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alignment (archaeology)
An alignment in archaeology is a co-linear arrangement of features or structures with external landmarks, in archaeoastronomy the term may refer to an alignment with an astronomically significant point or axis. "Alignment" may also refer to circumstantial or secondary type of evidence used to infer archaeological association of archeological features, such as postholes, by virtue of their physical relationships rather than stratigraphic ones. Types Large scale alignments The alignment of features on a site within or across several archaeological phases many times is an indication of a larger topology to the formation of features relating to activity in the archaeological record. Structures buildings and liner features such as ditches can all have common alignments that relate to a feature that is not exposed during excavation or is off-site. An example would be that a road has biased the alignment of features some way back from the actual road side. Another example will be co ...

Archaeological Section
In archaeology a section is a view in part of the archaeological sequence showing it in the vertical plane, as a cross section, and thereby illustrating its profile and stratigraphy. This may make it easier to view and interpret as it developed over time. Sections Half-sectioning is the usual method whereby one half of a feature is excavated and the remainder left in situ. Large linear features may be sectioned at intervals along their lengths. Sectioning has fallen out of favour in some schools of practice because detail is often missed in section that is important to the phasing of the site. Examples of detail that is revealed poorly "in section" include gravel or thin cobbled surfaces. The main problem with sections is the arbitrary location of their placement may "clip" or "just miss" contexts that reveal a different story form the one interpreted by the archaeologist. For instance thin liner features such as wheel ruts may be sectioned at an oblique angle giving the impress ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sequence (archaeological)
In archaeology, seriation is a relative dating method in which assemblages or artifacts from numerous sites in the same culture are placed in chronological order. Where absolute dating methods, such as radio carbon, cannot be applied, archaeologists have to use relative dating methods to date archaeological finds and features. Seriation is a standard method of dating in archaeology. It can be used to date stone tools, pottery fragments, and other artifacts. In Europe, it has been used frequently to reconstruct the chronological sequence of graves in a cemetery (e.g. Jørgensen 1992; Müssemeier, Nieveler et al. 2003). Contextual and frequency seriation Two different variants of seriation have been applied: contextual seriation and frequency seriation (Renfrew and Bahn 1996, pp. 116–117). Whereas contextual seriation is based on the presence or absence of a design style, frequency seriation relies on measuring the proportional abundance or frequency of a design sty ...
