Many people assume that the dates scientists quote of millions of years are as reliable as our knowledge of the structure of the atom or nuclear power. But the basic concept of radioactive dating, sometimes called radiometric dating, is not difficult, especially since all of us regularly calculate how much time has passed: for example, since our birth, or since we started on a walk. A swimming race is a familiar situation that illustrates the simple principles involved in measuring time. Once we understand what we actually need to do we can apply the same principles to radioactive dating, and see if the methods do what they are claimed to do. Picture a swimmer competing in a 1, metre race and an observer with an accurate wristwatch. We note that at the instant the swimmer touches the end of the pool our wristwatch reads and 53 seconds.

Chronological dating

The main difference between absolute and relative dating is that the absolute dating is a technique to determine the numerical age of a rock or a fossil whereas the relative dating is a technique that determines the relative age. Furthermore, absolute dating can be done with the use of radiometric dating while relative age is determined with respect to other layers. The four techniques used in absolute dating are radiometric dating, amino acid dating, dendrochronology, and thermoluminescence. Figure 1: Radiocarbon Date Calibration Curve. Relative dating is the technique used to determine the age by comparing the historical remaining to the nearby layers.

The emergence of man through the process of biological and cultural evolution is a story of long span of time. For the archaeologist and the prehistorian who deals with that long history of man, time is the most important consideration. The sequence of development of culture or the relationship between events that represent culture can be established only when events can be placed in proper time. Chronology, the study of events in time frame, is hence the central theme of archaeologist, like the geologist who deals with the story of earth history. In fact, chronology is one of the most fundamental issues in and perhaps a characteristic of archaeology.
