How do archaeologists determine how old an object is? Relative dating methods estimate whether an object is younger or older than other things found at the site. Relative dating does not offer specific dates, it simply allows to determine if one artifact, fossil, or stratigraphic layer is older than another.

Why do archaeologists use dating techniques?

Because deposits or artifacts will reveal change in style or frequency over time, archeologists must use other dating methods (usually absolute) to determine which end of the seriation is earlier and which is later.

What are some archaeology dating methods?

There are two main categories of dating methods in archaeology: indirect or relative dating and absolute dating. Relative dating includes methods that rely on the analysis of comparative data or the context (eg, geological, regional, cultural) in which the object one wishes to date is found.

What is dating in archeology?

Dating in archaeology is the process of assigning a chronological value to an event in the past. Chronological value can also be considered at different scales. Ordinal scale, often called relative, specifies older or younger but not the distance between events.

What are Chronometric dating techniques?

Chronometric dating, also known as chronometry or absolute dating, is any archaeological dating method that gives a result in calendar years before the present time. Archaeologists and scientists use absolute dating methods on samples ranging from prehistoric fossils to artifacts from relatively recent history.

What is Radiopotassium dating?

Potassium-argon dating or K-Ar dating is a radiometric dating method used in geochronology and archaeology. It is based on measurement of the product of the radioactive decay of an isotope of potassium (K) into argon (Ar).
