Excavation is the process of removing strata to study them. The goal of excavation is to check the layers of buried material and to create a record of what has been found. This information is then used to discuss the past. The purpose of excavation will vary depending on the project’s goals.
Excavation can be classified into two types: surface and underground. Surface excavation refers to digging above the surface, while underground excavations refer to the work done below ground. Both kinds of holes require different tools and techniques. In construction, excavating the surface can be used for digging a ditch or laying a foundation for a new structure. Another type of excavation is dredge excavation, which involves removing material underwater.
Surface excavations are often done manually. This can be done by hand or using a machine. Depending on the nature of the site and the type of objects to be recovered, excavations may require more or less advanced methods. For instance, a hole may include tracing to mark the exact position of artifacts. In addition, the process of excavation may also involve the use of a sample or strip map.
An archaeological excavation involves a thorough and meticulous process, and many rules exist for conducting excavations. The first is obtaining permission from the landowner. Then, it is necessary to consult with the local authority archaeologist to ensure the project does not harm the area. You will also need to obtain a Northern Ireland Environment Agency license.
An excavation is a crucial part of the construction. It helps move materials into a cavity and prepare the ground for a new structure. There are different types of holes used by building companies. Your choice will depend on the type of material you’re trying to work with and the purpose.
An excavation guideline is vital information that enables an archaeologist to manage the risks and prevent any damage to the site. The policy includes detailed site information, location, and survey points. This information allows researchers to compare the place to nearby structures and natural landforms. It also helps them to determine settlement patterns.
An archaeologist can also develop a chronology of archaeological activity at a site through stratigraphic interpretation. This is done by studying the layers of sediment. The stratigraphic relationship of archaeological layers is also important to understand the date and place of occupation. To do this, archaeologists need to find a context for the archaeological finds.
A typical excavation involves clearing large areas, which is called stripping. The process removes topsoil, which consists of vegetation and the upper layer of soil.
