For deep sea corals, a combination of radiocarbon dating and uranium-thorium dating can be used. The carbon-14 date represents the age of the coral and the water, whereas the uranium-thorium date reflects the coral itself. This can provide information on past deep sea circulation rates.
Beta Analytic is expanding its services for groundwater and, for a limited time, is including free additional measurements when clients submit samples for radiocarbon dating. The laboratory is including isotope ratios for deuterium (dD) and oxygen (d18O) at no additional cost for all water samples submitted for accelerator mass spectrometry (AMS) dating until August 2016.
It is possible to date fired clay bricks, but it depends on how the bricks were manufactured and what types of contamination may have been absorbed into the bricks since they were put in place.
We have dated beeswax, sometimes with good success, sometimes not. This is because no pretreatment for organic contaminants can be applied. Thus, if any younger or older carbon has been incorporated in the beeswax, it will be represented in the result.
