Rehydroxylation rhx dating
Further ya is defined as: It follows that the age of the sample (ta) is: These relationships are illustrated in Figure 4.
Here the mass contribution of the three different types of water is clearly seen. Mass gain versus time following reheating at 500°C (a) the characteristic two stage mass gain.
The rehydroxylation process is a chemical reaction and is based on temperature.
This technique is based upon dating the Stage II kinetics of the rehydroxylation process using...
more Rehydroxylation is a developing method of dating fired materials that was introduced to fired brick in 2009 and archaeological pottery in 2012.
This is the combined mass gain of all the three types of water identified T0 T1 T2 (~27,000 data points).
The contribution these components make to the overall mass can be separated out as shown by graphs (b) and (c) (b) mass gain due to T0 T1 only and this eventually stops when the sample has equilibrated with the ambient conditions.
Lack of complete DHX at the scales we have observed can result in the over-estimation of ceramic ages by decades to tens of thousands of years, depending largely on the age of the sample, and the amount of residual OH present.
