All date options are reported to the archaeologist, then makes a decision as to which best matches the other data from the site (Sternberg 1982, Eighmy 1990).
In contemporaneity studies, or relative dating, sample VGPs are compared to each other to determine whether they are statistically different at the 5% significance level.
a research instrument primarily used in physics to accelerate streams of charged subnuclear particles to high velocities in order to sort and analyze them.
Proteins are composed of different combinations of amino acids assembled in chain-like molecules.
Amino acids are primarily composed of carbon, oxygen, hydrogen, and nitrogen.
The remaining mean VGPs cannot be statistically distinguished from that of the sample, and their associated date range(s) is assigned to the sample VGP.
Because secular variation is a repetitive looping motion through time, it is possible to have multiple date options for a feature.
Within these weaker areas the local directions and intensities change gradually (secular variation).
A compass does not point to the true North Pole but to direction that is a function of the North Magnetic Pole and the local secular variation to yield a magnetic declination.
Unlike radiocarbon or, in some cases, even tree rings, the data recovered from an archaeomagnetic sample directly refer to a specific cultural event of archaeological interest (Dean 1978).
Thus, an archaeomagnetic sample, in theory, should more accurately date the target event than other dating sources (Wolfman 1990a:346).
Archaeomagnetic dating is the study and interpretation of the signatures of the Earth's magnetic field at past times recorded in archaeological materials.
