The thermal history framework provided by AFTA forms a solid basis for this procedure. Helium diffusion from apatite: general behaviour as illustrated by Durango fluorapatite.
By incorporating both AFTA and (U-Th)/He ages into the modelling, a more restricted range of thermal history solutions can be extracted. Journal of Geophysical Research, 105 (B2), 2903-2914.
This period of courtship is sometimes seen as a precursor to engagement or marriage.
With the use of modern technology, people can date via telephone or computer or meet in person.
This term may also refer to two or more people who have already decided they share romantic or sexual feelings toward each other.
These ages are progressively reset by heating, due to the diffusive loss of the radiogenic helium (analogous to the annealing of fission tracks), with total loss occurring at temperatures around 80 to 90C (for timescales involving millions of years).
Particularly when integrated with information from AFTA and other thermal indicators (e.g. (Uranium thorium)/helium dating of apatite: experience with samples from different geochemical environments.
Reliable reconstruction of thermal histories in sedimentary basins is a key aspect of reducing exploration risk, e.g.
