types of excavation in archaeology

[1] An excavation site or "dig" is the area being studied. In archaeology, excavation is the exposure, processing and recording of archaeological remains. The Parthenon in Athens and the Egyptian pyramids are the exceptions and not the norm (Figure 8.1). For example, the presence of an anomalous medieval pottery sherd in what was thought to be an Iron Age ditch feature could radically alter onsite thinking on the correct strategy for digging a site and save a lot of information being lost due to incorrect assumptions about the nature of the deposits which will be destroyed by the excavation process and in turn, limit the sites potential for revealing information for post-excavation specialists. Archaeological excavation is an unrepeatable process, since the same area of the ground cannot be excavated twice. The majority of the reports of excavations done in Louisiana are found in reports filed with the Louisiana Division of Archaeology. Stratigraphic excavation involves a process of cleaning or "troweling back" the surface of the site and isolating contexts and edges which are definable as either: Following this preliminary process of defining the context, it is then recorded and removed. Spot dating also forms part of a confirmation process, of assessing the validity of the working hypothesis on the phasing of site during excavation. Topsoil excavation is removal of the exposed layer of the earth’s surface, including vegetation. [9][8], The most dramatic changes that occurred over time is the amount of recording and care taken to ensure preservation of artifacts and features. Classical Archaeology: Classical archaeology is the type of archaeology that deals with most civilized classical cultures of the world, i.e. Often, owing to practical considerations or error, the process of defining the edges of contexts is not followed and contexts are removed out of sequence and un-stratigraphically. Common Misconceptions Methods of Archaeology History of Archaeology Public Role in Archaeology References. Weighing and Measuring: The artifacts obtained in excavations are carefully analyzed by weighing and measuring them. [7] It is largely based on the Law of Superposition. The archaeological recordconsists of artifacts, architecture, biofactsor ecofacts and cultural landscapes. No tools left on the site were used, and there were no immediate material "byproducts" of the "primary" activity. Dating methodology in part relies on accurate excavation and in this sense the two activities become interdependent. A builder built a wall and back-filled the trench. By the process of excavation, the land is cleaned from tree roots, … The process of interpretation in practice will have a bearing on excavation strategies on site so "phasing" a site is actively pursued during excavation where at all possible and is considered good practice.

The types of excavation based on dug out material include topsoil excavation, earth excavation, rock excavation, muck excavation and unclassified excavation. In most cases, these are not even designed specifically for archaeology. Several other techniques are available depending on suitability and time constraints. [19] A relationship that is later in the sequence is sometimes referred to as "higher" in the sequence and a relationship that is earlier "lower" though the term higher or lower does not itself imply a context needs to be physically higher or lower. It is more useful to think of this higher or lower term as it relates to the contexts position in a Harris matrix, which is a two-dimensional representation of a site's formation in space and time. The terminology of these larger clusters varies depending on practitioner, but the terms interface, sub-group, group and land use are common. Some success has been achieved with the use of cement mixers and bulk sieving. Or anomalous information could show up errors in excavation such as "undercutting". [6] Basic information about the development of the site may be drawn from this work, but to understand finer details of a site, excavation via augering can be used. It is by analysis of this sequence or record that excavation is intended to permit interpretation, which should lead to discussion and understanding. The purpose of trial excavations is to determine the extent and characteristics of archaeological potential in a given area before extensive excavation work is undertaken. [25] Archaeologists examine and analyze the classical history of these civilizations which is spread over 2,000 years. The use of sieving is more common on research-based excavations where more time is available. Multiple fills seen in section would mean multiple contexts. Archaeological excavation is the controlled examination of the buried deposits and features that make up archaeological sites and monuments. Phase is the most easily understood grouping for the layman as it implies a near contemporaneous Archaeological horizon representing "what you would see if you went back to a specific point in time". Understanding a site in modern archaeology is a process of grouping single contexts together in ever larger groups by virtue of their relationships.
