Relative Dating Analysis

Decent Essays

An enormous amount of planning and research go into the excavation of an archaeological site. Before any kind of digging can take place, an initial survey of the area of interest must be completed. Once it has been confirmed that there are indeed fossil beds present, months of careful strategizing follow before ground is finally broken. After the real digging begins, the painstaking process of unearthing and meticulously cataloging artifacts that are found ensues. All of this must take place before the laborious process of analyzing and then dating these newfound artifacts can happen. From this point, archaeologists are able to begin the fascinating, and often times difficult journey to discover an artifact’s age. Although this process can …show more content…

Some prefer relative dating, a method that is used to provide a geological sequence of deposits, but that unfortunately does not yield any age estimates for the deposits in question (Lewis, et al., 2013). Others prefer the method of chronometric dating, a method that not only results in geological order but also an absolute age (Lewis, et al., 2013). This method is much more exact than relative dating, as it can yield an actual estimate of an artifact’s …show more content…

As time passes, the radioactive isotopes in geological substances begin to break down and form new isotopes (Lewis, et al., 2013). Using the modern knowledge of the rate of decay, scientists are able to ascertain the period of time that an artifact has been decaying, and then calculate an estimate for its age. The potassium-argon method is a great example of accurate dating. The decay of potassium in geologic substances creates argon gas over time, creating certain proportions of argon gas to potassium (Lewis, et al., 2013). When scientists reheat these rocks, they can measure the amount of argon gas that is released and form an accurate guess as to when the rock was formed (Lewis, et al.,
