Absolute dating the problem: beginning in 1911, arthur holmes began a long career of applying the concept of radiometric dating to rocks. Relative dating (steno's laws): long before geologists tried to quantify the age of the earth they developed techniques to determine which geologic events preceded another, what are termed relative age” relationships.
To accompany the geologic these are most commonly obtained via radiometric dating methodology and data involved in constructing this geological time scale. Absolute dating is used to determine a precise age of a rock or fossil through radiometric dating methods this uses radioactive minerals that occur in rocks and fossils almost like a geological clock. Absolute dating is a method of determining the specific date of a paleontological or archaeological artifact or location based on a specific time scale or calendar.
