Limits to relative dating are that it cannot provide an accurate year or a specific date of use.
The style of the artefact and its archaeology location stratigraphically are required to arrive at a relative date.
Chronology of rock art, ranging from Paleolithic to present times, is a key aspect of the archaeology of art and one of the most controversial.
It was based for decades in nonscientific methods that used stylistic analysis of imagery to establish one-way evolutionary schemes.
Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events.
Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.
b) Absolute These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials.
Two broad categories of dating or chronometric techniques that archaeologists use are called relative and absolute dating.
The absolute dating method first appeared in 1907 with Lord Rutherford and Professor Boltwood at Yale University, but wasn’t accepted until the 1950s.
The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope.
The scholar most associated with the rules of stratigraphy (or law of superposition) is probably the geologist Charles Lyell.
The basis for stratigraphy seems quite intuitive today, but its applications were no less than earth-shattering to archaeological theory.
