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.
