Stratigraphy
|
Relative Dating
Dating different levels to establish a chronological sequence. However, human activities, erosion and animal burrowing can make this method inaccurate |
|
|
Typology
|
Relative Dating
Groups of artefacts such as pottery can be arranged in a sequence from the earliest to the latest types based on distinct features and the simplicity or how elaborately the artefact is made |
|
|
The Three Age System
|
Relative Dating
Based on technology of stone, bronze, iron then further divided in early, middle, late. |
|
|
Radiocarbon dating
|
Absolute Dating
Can date organic materials between 50,000 and 400 years old. When a living thing dies they stop absorbing Carbon 14. It then decays at a constant rate and scientists can measure the emissions to work out when the organism died |
|
|
AMS radiocarbon dating
|
Absolute Dating
Can date older material and is more accurate than regular radiocarbon dating |
|
|
Dendrochronology
|
Absolute Dating
Tree ring dating used for trees or timber objects. The age can be determined by counting the growth rings in a cross section of the timber. Scientists can work out a continuous or master sequence for a region of trees going back thousands of trees. |
|
|
Potassium - argon dating
|
Absolute Dating
Used to date volcanic rock |
|
|
Uranium series dating
|
Absolute Dating
Used to date rocks containing calcium carbonate found as stalagmite in caves |
|
|
Fission track dating
|
Absolute Dating
Determines thermal age of artefacts, for example fired ceramics |
|
|
Thermoluminescence (TL) dating
|
Absolute Dating
Can date pottery and inorganic that is over 50,000 years old. Heating the ceramic or material to 500 degrees Celsius creates a flash of light called Thermoluminescence. Scientists measure the amount of light emitted to determine the original firing date |
|
|
X-ray fluorescence analysis
|
Determines metal composition
|
