what methods do archaeologists use to find sites

Generally, archaeologists search for subtle indicators of buried sites, such as potsherds peeking out of the soil or grassy mounds in otherwise flat terrain. During excavation, archaeologists often use stratigraphic excavation to remove phases of the site one layer at a time. What does an Archaeologist do? The term Archaeology is used to describe the discovery and research of societies and individuals. But most finds are the result of a great deal of work and planning. Archaeological Methods. State one way that archaeologists decide where to dig. In recent years, archaeologists have begun to use new methods to find archaeological sites that had previously been overlooked. Seriation or Artifact Sequencing. There are several ways an archaeologist knows where to dig, with new methods of finding sites being developed almost every day. I will briefly describe what each of those methods entail, to give you a better idea of how archaeologists locate sites. This information helps government agencies … Give one method used by archaeologists to locate sites for excavation. In recent years, archaeologists have begun to use new methods to find archaeological sites that had previously been overlooked. All methods can be classified into two basic categories: a) Relative dating methods : Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events. The answer is that there are many ways to find archaeological sites. Archaeology plays a very significant role in anthropology because archaeology is defined as being the study of human history and prehistory via the excavation of sites and the analysis of artifacts and other physical remains. This blog entry focuses on surveys. The methods can be put into three regions: selecting sites, collecting artifacts and ordering the past artifacts. [7] This is done usually though mechanical means where artifacts can be spot dated and processed through methods such as sieving or flotation. Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things. Critically assess the pros and cons of the methods you identify using relevant examples. (2011 OL) 2. Frederick Bligh Bond. Archaeologists have several methods for figuring out an artifact’s age. The simplest and oldest identification method is a pedestrian survey: looking for evidence of human activity, either on unstructured strolls or when walking in a grid. What is a site? Unless the evidence is crystal clear – like those broken pots – such surveys usually need a trained eye to read the clues. What tools do archaeologists use for excavation? Free Presentations in PowerPoint format. The most common digging tools are picks, shovels, and trowels. Meet the team + What we do. Archaeologists also use non-invasive techniques to survey sites known as remote sensing. Archaeologists use scientific sampling techniques to guide them as to where they need to dig on the site. Archaeologists look for sites to learn about human cultures of the past. How do archaeologists find sites to explore? These are described below. If you were an archaeologist, how would you decide where to dig? In recent years, archaeologists have begun to use new methods to find archaeological sites that had previously been overlooked. A feature, for example a pit or a ditch, consists of two parts: the cut and the fill. There are many methods, which archaeologists use to collect data, including desk-based research, geotechnical survey and geophysical survey. Community Archaeology. Originally developed for climate science, the method is now an invaluable tool for archaeologists, who can track up to 13,000 years of history using tree ring chronologies for over 4,000 sites … An archaeologist measures this decrease to find out how long ago the organism died. These include talking to locals, learning what to look for through experience, employing modern technology, and walking surveys. Archaeologists working in the southwestern United States use two methods to locate new sites: surveys and test trenching. One method is called carbon-14 dating. Today, a team of local archaeologists is working to unlock the secrets of their mysterious island. The process starts when someone needs a piece of land examined to see whether sites are present. Stratigraphy is based on the law of superposition--like a layer cake, the lowest layers must have been formed first. They do this by excavating the remains of past human societies. After an organism dies, the amount of carbon-14 decreases at a certain rate. We are a Chartered Institute for Archaeologists Registered Organisation, and the first-ever CIfA Accredited Fieldschool. Archaeologists are scientists that study how humans lived in the past. Name two instruments which an archaeologist would use to excavate a site. Features dug into the natural subsoil are normally excavated in portions in order to produce a visible archaeological section for recording.
