Carbon 14 dating system definition

Relative-dating techniques are nearly always applicable but are not precise and require calibration.Correlation techniques are locally useful and depend on recognition of an event whose age is known, such as a volcanic eruption or a paleomagnetic reversal.In fact, it has fluctuated a great deal over the years.This variation is caused by both natural processes and human activity.Geologic studies of active tectonism are greatly aided by definition and time calibration of local stratigraphic sequences.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.Geologic assessment of active tectonism depends on two key measures: the age and the amount of deformation of a given stratigraphic unit.The amount of deformation can normally be measured with greater accuracy than the age.

It is an essential technology that is heavily involved in archaeology and should be explored in greater depth.

The technology uses a series of mathematical calculations—the most recognizable of which is known as half-life—to estimate the age the organism stopped ingesting the isotope.

Unfortunately, the amount of Carbon-14 in the atmosphere has not been steady throughout history.

Adequate age control is thus a limiting factor in studies of active tectonism.

About 26 dating techniques can be applied to dating deposits and deformation of late Cenozoic age (past few million years).
