Archaeological Natural
In archaeology, natural is a term to denote a layer (stratum) in the stratigraphic record where there is no evidence of human impact on the environment. While there may be "natural" layers interbedded with archaeologically interesting layers, such as when a site was abandoned for long periods between occupations, the top (or horizon) of the natural layer below which there is no anthropogenic activity on site, and thus where the archaeological record begins, is the point to terminate digging.Barker, Philip (1993) ''Techniques of archaeological excavation'' Psychology Press, New Yorpage 79 Usually it is the underlying geological makeup of the site that was formed by geologic processes. It is the goal of complete excavation to remove the entirety of the archaeological record all the way to the "natural", leaving only the natural deposits of pre-human activity on site. If the excavation is related to development, the impact assessment may stipulate excavation will cease at a certa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeology
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the adven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geoarchaeology
Geoarchaeology is a multi-disciplinary approach which uses the techniques and subject matter of geography, geology, geophysics and other Earth sciences to examine topics which inform archaeological knowledge and thought. Geoarchaeologists study the natural physical processes that affect archaeological sites such as geomorphology, the formation of sites through geological processes and the effects on buried sites and artifacts post-deposition. Geoarchaeologists' work frequently involves studying soil and sediments as well as other geographical concepts to contribute an archaeological study. Geoarchaeologists may also use computer cartography, geographic information systems (GIS) and digital elevation models (DEM) in combination with disciplines from human and social sciences and earth sciences. Geoarchaeology is important to society because it informs archaeologists about the geomorphology of the soil, sediment, and rocks on the buried sites and artifacts they are researching. B ...

Deposit Model
In the field of archaeology a deposit model is a method of identifying the character and degree of survival of buried archaeological remains over a specified area without necessarily excavating the whole area. Following the introduction of archaeology into the planning process in most western nations, the importance of gathering as much information as possible on a site without digging it up has grown. Such information can be used to inform the decisions made by planners, developers and archaeologists about the necessity for, and nature of, any archaeological work in advance of new building. A deposit model uses the results of previous excavations and other intrusive archaeological investigations to estimate the nature of the archaeology over a wider area. Productive excavations in one area would suggest that land nearby would also be productive. Since the buried archaeological record is essentially a volume of earth trapped between the two archaeological horizons defined by the ...

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] |
Archaeological Horizon
In archaeology, the general meaning of horizon is a distinctive type of sediment, artefact, style, or other cultural trait that is found across a large geographical area from a limited time period. The term derives from similar ones in geology, horizon or marker horizon, but where these have natural causes, archaeological horizons are caused by humans. Most typically, there is a change in the type of pottery found and in the style of less frequent major artefacts. Across a horizon, the same type of artefact or style is found very widely over a large area, and it can be assumed that these traces are approximately contemporary. General The term is used to denote a series of stratigraphic relationships that constitute a phase or are part of the process of determining the archaeological phases of a site. An archaeological horizon can be understood as a break in contexts formed in the Harris matrix, which denotes a change in epoch on a given site by delineation in time of finds found ...

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] |
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] |

Archaeological Field Survey
In archaeology, survey or field survey is a type of field research by which archaeologists (often landscape archaeologists) search for archaeological sites and collect information about the location, distribution and organization of past human cultures across a large area (e.g. typically in excess of one hectare, and often in excess of many km2). Archaeologists conduct surveys to search for particular archaeological sites or kinds of sites, to detect patterns in the distribution of material culture over regions, to make generalizations or test hypotheses about past cultures, and to assess the risks that development projects will have adverse impacts on archaeological heritage. The surveys may be: (a) ''intrusive'' or ''non-intrusive'', depending on the needs of the survey team (and the risk of destroying archaeological evidence if intrusive methods are used) and; (b) ''extensive'' or ''intensive'', depending on the types of research questions being asked of the landscape in quest ...

Debitage
In archaeology, debitage is all the material produced during the process of lithic reduction – the production of stone tools and weapons by knapping stone. This assemblage may include the different kinds of lithic flakes and lithic blades, but most often refers to the shatter and production debris, and production rejects. Debitage analysis Debitage analysis, a sub-field of lithic analysis, considers the entire lithic waste assemblage. The analysis is undertaken by investigating differing patterns of debris morphology, size, and shape, among other things. This allows researchers to make more accurate assumptions regarding the purpose of the lithic reduction. Quarrying activities, core reduction, biface creation, tool manufacture, and retooling are believed to leave significantly different debitage assemblages. Lithic manufacture from a quarried source, or from found cobbles also leave different signatures. Some claim that they can determine the sort of tools used to crea ...

Human Impact On The Environment
Human impact on the environment (or anthropogenic impact) refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of society is causing severe effects including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth, overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, have been proposed as representing catastrophic risks to the survival of the human species. The term ''anthropogenic'' designates an effect or object resulting from human activity. The term was first used in the technical sense by Russian geologist Alexey Pavlov, and it w ...
