Explain the concept of dating in archaeology

Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order. Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks. The atoms of some chemical elements have different forms, called isotopes.

Absolute dating - Wikipedia

By: Jessika Toothman. Prior to the development of radiocarbon dating , it was difficult to tell when an archaeological artifact came from. Unless something was obviously attributable to a specific year -- say a dated coin or known piece of artwork -- then whoever discovered it had to do quite a bit of guesstimating to get a proper age for the item. The excavator might employ relative dating, using objects located stratigraphically read: buried at the same depth close to each other, or he or she might compare historical styles to see if there were similarities to a previous find.

An Introduction to Seriation

Relative dating is the science of determining the relative order of past events i. In geology, rock or superficial deposits , fossils and lithologies can be used to correlate one stratigraphic column with another. Prior to the discovery of radiometric dating in the early 20th century, which provided a means of absolute dating , archaeologists and geologists used relative dating to determine ages of materials. Though relative dating can only determine the sequential order in which a series of events occurred, not when they occurred, it remains a useful technique.

He assumed that the change in styles was an evolutionary one, and, if you could quantify that change, he surmised it might be used to indicate which cemeteries were older than others. Petrie's notions about Egyptology—and archaeology in general —were revolutionary. His worrying about where a pot came from, what period it dated to, and what that meant to the other objects buried with it was light-years away from the ideas represented in this photo dated to , in which "Egyptian pots" was considered enough information for the thinking man. Petrie was a scientific archaeologist, probably close to our first example.
