Chronometric dating, also known as chronometry or absolute dating, is any archaeological dating method that gives a result in calendar years before the present time.
Chronometric dating has advanced since the 1970s, allowing far more accurate dating of specimens.
The amount of deformation can normally be measured with greater accuracy than the age.
Adequate age control is thus a limiting factor in studies of active tectonism.
Because all dating techniques may be subject to considerable error, reliability should be assessed by stratigraphic consistency between results of different dating methods or of the same method.
Paleontology seeks to map out how life evolved across geologic time.
