Geologists often need to know the age of material that they find. As a member, you'll also get unlimited access to over 79, lessons in math, English, science, history, and more. Most absolute age determinations in geology rely on radiometric methods. Dating techniques are procedures used by scientists to determine the age of rocks, fossils, or artifacts. Absolute dating can be achieved through the use of historical records and through the analysis of biological and geological patterns resulting from annual climatic variations, such as tree rings dendrochronology and varve analysis.

Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Cart 0. Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life. Although relative ages can generally be established on a local scale, the events recorded in rocks from different locations can be integrated into a picture of regional or global scale only if their sequence in time is firmly established. But what is exactly a fossil and how is it formed?
