Forms of dating artifacts
More recently is the radiocarbon date of 1950 AD or before present, BP.
There are two techniques for dating in archaeological sites: relative and absolute dating.
Archival research is often the first step in archaeology.
This research uncovers the written records associated with the study area.
In relative dating, archaeologists interpret artifacts based on their positions within the (horizontal layering) of the soil.
The study of stratigraphy follows the excavation axiom "last in, first out"--meaning that an archaeologist usually removes soil layers in the reverse order in which they were laid down (see Figure 1).
During and after an excavation, an archaeologist confronts a bewildering collection of artifacts, drawings, and photographs to decipher and relate to one another.
Using both relative and absolute dating methods, an archaeologist can often place a site within a larger chronological framework.
Both absolute and relative dating approaches are employed.Although relative dating can work well in certain areas, several problems arise.
