Geologic Time and Dating When looking at the history of the earth and the record of time preserved in the rock or what is called the ROCK RECORD, two types of dating are distinguished. ABSOLUTE DATING puts a date on an event in years. For example, something may be dated at 11,500 years BP (before present) plus or minus 500 years. 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. Relative vs Absolute Dating . Dating is a technique used in archeology to ascertain the age of artifacts, fossils and other items considered to be valuable by archeologists. There are many methods employed by these scientists, interested in the old, to get to know the age of items. It is possible to tell the number of years ago a particular ... Absolute dating is expensive and time-consuming. It works best for igneous and metamorphic rocks. The following are the major methods of relative dating. Radiometric dating: This technique solely depends on the traces of radioactive isotopes found in fossils. The rate of decay of these elements helps determine their age, and in turn the age of ...
