Archaeological dating techniques definitions

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. But by using these imprecise methods, archeologists were often way off.

Stratigraphy is a term used by archaeologists, geologists, and the like to refer to the layers of the earth that have built up over time. Stratification is defined by the depositing of strata or layers, one on top of the other, creating the ground we walk on today. Stratigraphy is a relative dating system, as there are no exact dates to be located within the ground, and areas can build up at different rates depending on climate, habitation, and weather. This is why context and association are so important when excavating. If multiple objects are found in association with each other, it is a good indication that they were buried at the same time. If coins are found within strata, or pieces of organic material that can radio carbon dated, then more exact dates can be attributed. Once a collection is formed over various layers in the earth, we are then able to create a proper timeline.

Dating in Archaeology
Archaeologists use many different techniques to determine the age of a particular artifact, site, or part of a site. Two broad categories of dating or chronometric techniques that archaeologists use are called relative and absolute dating. Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things. Stratigraphy is based on the law of superposition--like a layer cake, the lowest layers must have been formed first. In other words, artifacts found in the upper layers of a site will have been deposited more recently than those found in the lower layers.
Chronological dating , or simply dating , is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a "dating method". Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history , archaeology , geology , paleontology , astronomy and even forensic science , since in the latter it is sometimes necessary to investigate the moment in the past in which the death of a cadaver occurred.
