This page is a glossary of archaeology, the study of the human past from material remains.
- absolute age
- The age of an object with reference to a fixed and specific time scale, as determined by some method of absolute dating, e.g. 10,000 BP or 1.9 mya.
- absolute dating
- Ascertaining the age of an object with reference to a fixed and specific time scale (e.g. calendar years or ), as opposed to .
- aerial archaeology
- Archaeological investigations conducted from the air, e.g. using aerial photography or satellite imagery.
- A person interested in the collection, curation and/or study of antiquities, particularly in reference to the intellectual tradition that developed in Europe in the 16th–17th centuries and is considered a precursor to modern archaeology.
- Ancient artefacts, particularly in the context of their trade and collection.
- The ancient past, in particular the period of the earliest historic civilizations (see ).
- Subdiscipline devoted to the analysis of plant remains in the archaeological record.
- See .
- A person engaged in the study or profession of archaeology.
- The academic discipline concerned with the study of the human past through material remains.
- A physical object made by humans.
- A set of artefacts or ecofacts found together, from the same place and time. Can refer to the total assemblage from a site, or a specific type of artefact, e.g. lithic assemblage, zooarchaeological assemblage.
- Two or more excavated objects that are thought to be related are said to be in association, e.g. artefacts discovered in close proximity within the same context, or architectural features thought to have been standing at the same time.
- 1. To re-fill a trench once an excavation has been completed.
- 2. Material used for backfilling, usually spoil from the original excavation.
- 3. Material used for backfilling, is usually selected material from the excavation minimizing the size of aggregates to max. 150 mm wither by crushing or selecting from the sulphrus material and mixed with dune or washed sand, quarry scalping material.
- 4. Backfill is done in layer by layer not exceeding 300 mm (in some places 150 mm) of the thickness compacted to maximum extent of its dry density.
- A wall of earth left in place between excavated areas in order to maintain the structural integrity of the trench and/or expose a section to aid in interpretation.
- Type of stone tool; a small blade characteristic of Upper Palaeolithic Europe.
- C14 dating
- See .
- 1. As in common usage, information relating to where an artefact or feature was found and what it was found in association with.
- 2. In single context excavation, a well-defined stratigraphic unit relating to a single depositional event, used as the primary unit for recording and analysis.
- An archaeological culture is a recurring assemblage of artifacts from a specific time and place that may constitute the material culture remains of a particular past human society.
- An informal term for an archaeological excavation.
- dry sieving
- A method of sifting artefacts from excavated sediments by shaking it through sieves or meshes of varying sizes. As opposed to , which uses water.
- Earthworks are artificial changes in land level, typically made from piles of artificially placed or sculpted rocks and soil
- environmental archaeology
- Environmental archaeology is the science of reconstructing the relationships between past societies and the environments they lived in.
- Excavation is the exposure, processing and recording of archaeological remains.
- Archaeological investigations taking place in the field, e.g. excavations or surveys.
- An informal term for artifacts, features and other things discovered by archaeologists.
- finds processing
- The preparation of finds from an excavation for storage or further specialist analysis, typically including washing, labelling, sorting and listing in an inventory.
- finds specialist
- An archaeologist who specialises in the analysis of a particular type of find.
- A method for recovering very small artefacts (particularly small fragments of bone and botanical remains) from excavated sediments using water.
- occupation earth
- set of deposits believed to represent in-situ settlement at an archaeological site, containing pottery sherds, ashes, animal remains, etc.
- See .
- pollen diagram
- pollen profile
- pollen spectrum
- A series of side-by-side graphs, produced by archaeobotanists and palynologists, showing the frequency of different types (species) of pollen in a soil sample by depth. Usually presented vertically, with the shallowest samples at the top and the deepest at the bottom, to represent a pollen core or other stratified deposit. The depth of the sample corresponds roughly to how old it is, and therefore the vertical axis may also contain an estimate of its absolute age. Used to visualise the environmental history of the place where the sample was taken.
- A fragment of pottery. In specialised usage sherd is preferred over the more common spelling shard.
- radiocarbon dating
- absolute dating technique used to determine the age of organic materials less than 50,000 years old. Age is determined by examining the loss of the unstable carbon-14 isotope, which is absorbed by all living organisms during their lifespan. The rate of decay of this unstable isotope after the organism has died is assumed to be constant, and is measured in half-lives of 5730 + 40 years, meaning that the amount of carbon-14 is reduced to half the amount after about 5730 years. Dates generated by radiocarbon dating have to be calibrated using dates derived from other absolute dating methods, such as dendrochronology and ice cores.
- A period of time spent working on a particular site or field project.
- A section is a view of the archaeological sequence showing it in the vertical plane, as a cross section, showing the straigtraphy.
- shovel test pit
- test holes, usually dug out by a shovel, in order to determine whether the soil contains any cultural remains that are not visible on the surface.
- A colloquial term for professional excavators working in cultural resources management in the United States.
- The use of sieves, screens, and meshes to improve the recovery rate of artefacts from excavated sediments (). Can be divided into and .
- Loose sediment excavated from a trench.
- spoil heap
- A pile of sediment from an excavation, usually located next to a trench.
- The classification of objects according to their physical characteristics.
- watching brief
- A formal programme of observation and investigation conducted during any operation carried out for non-archaeological reasons.
- wet sieving
- The use of flowing water to force excavated sediment through a screen or mesh and recover small artefacts. It is more effective than in heavier soils and, as part of the process of flotation, can be used to recover very small organic remains.
- Subdiscipline devoted to the analysis of animal remains in the archaeological record.
