Combination of relative dating and absolute dating techniques to create


Both methods are vital to piecing together events of the past from the recent back to a time before humans and even before complex life and sometimes, researchers will combine both methods to come up with a date.



For further details, see uranium-lead dating section below.Luminescence/Thermoluminescence: This measures the amount of light emitted from energy stored in rocks.Geological materials store energy from the sun at a constant and known rate.These energy levels are measured against what they should be if they had not been interfered with and we are able to obtain a date of the intervention.

This is used in archaeological and anthropological contexts (7) in areas where radiocarbon dating is problematic such as dating post AD1700 and where dates from RC14 is anomalous or lacks data. Potassium-argon dating: Typically used in geology and geochronology, K-Ar dating has a minimum age of around 100,000 years ago (but can be problematic when examining material close to this earliest date) up to a top end of around 4.5 billion years.

When these materials are heated to high temperatures through such processes as pottery firing, that is released.

    Sep 11, 2013. Geologists analyze geologic time in two different ways in terms of relative geologic age, and in terms of absolute or numeric geologic age. The combination of these two types of geologic ages makes a complete record of earth's geologic history in terms of the order of events and in terms of how many.…
