Methods of dating archaeological findings

29 Apr

Archaeologists also use non-invasive techniques to survey sites known as remote sensing.There are many methods including aerial photography which is simply taking pictures from an airplane, hot air balloon or even a remote controlled drone; ground penetrating radar which is used to locate artifacts hidden below ground, and LIDAR, which uses lasers to scan the surface from the air through vegetation.After archaeologists have thoroughly surveyed the site they begin excavation. Then archaeologists excavate the site using trowels, shovels, and various other tools.They start by setting up a grid and connecting the grid to a datum. They carefully remove dirt and note the precise location of any artifacts found.

This family of dating methods, some more than a century old, takes advantage of the environment’s natural radioactivity.

This uses the decay of carbon and the ratio of C-12 to C-14 to determine the age of the artifact. It is also not very accurate for more recent artifacts.

Using all of the information about the artifacts, including context, typology, dating and more, archaeologists can piece together the events and culture of past society.

A feature is evidence of a human activity that is not movable, and usually has a vertical component.

An aspect of a site that is only horizontal, such as a road, is not a feature.
