Optically stimulated luminescence dating of young sediments a review marissa ribisi dating

Luminescence ages have an uncertainty of at least 4–5 %, mainly due to systematic errors in both dose rate (conversion factors) and equivalent dose (source calibration) estimation.

In most cases, the uncertainty will be higher, due to random errors (e.g., spread in equivalent doses) or uncertainty in assumptions (e.g., water content fluctuations, burial history).

They are now largely used to date not only palaeontological or organic remains, but also minerals that characterise detrital clastic sedimentary material.For example, the site cannot determine your email name unless you choose to type it.Allowing a website to create a cookie does not give that or any other site access to the rest of your computer, and only the site that created the cookie can read it.This approach has been extended to age estimation for single grains, opening up a wider range of potential environments and new possibilities for understanding postdepositional grain movement.Ongoing research offers the possibility of significant age range extension and novel applications including low-temperature thermochronology.
