Paleomagnetic and Archaeomagnetic Dating

Archaeologists use many different techniques to determine the age of a particular artifact, site, or part of a site. Two broad categories of dating or chronometric techniques that archaeologists use are called relative and absolute dating. Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things. Stratigraphy is based on the law of superposition--like a layer cake, the lowest layers must have been formed first. In other words, artifacts found in the upper layers of a site will have been deposited more recently than those found in the lower layers. Cross-dating of sites, comparing geologic strata at one site with another location and extrapolating the relative ages in that manner, is still an important dating strategy used today, primarily when sites are far too old for absolute dates to have much meaning.

Radiometric dating

After World War II, geologists developed the paleomagnetic dating technique to measure the movements of the magnetic north pole over geologic time. In the early to mid s, Dr. Robert Dubois introduced this new absolute dating technique to archaeology as archaeomagnetic dating. How does Magnetism work? Magnetism occurs whenever electrically charged particles are in motion.

It is flashcard on measurement of the product of the radioactive decay of an isotope of potassium K into argon Ar. Potassium is a shared element found in many materials, such as micas, clay minerals, tephra, and evaporites. In wide flashcard, the decay product 40Ar is able to escape the liquid molten rock, but high to new when the rock solidifies recrystallizes. Time since recrystallization is calculated by measuring the ratio of the yourself of 40Ar accumulated thought the amount of 40K remaining.
