Relative dating in archaeology presumes the age of an artefact in relation and by comparison, to other objects found in its vicinity.
Slow Dating.com, a UK site, is unusual in that organises speed dating events rather than focusing on online speed dating.

Pour la première fois, ces ciments monophasés ou rarement polyphasés ont pu être datés du stade isotopique 3 ou peut-être 4 (sous-étages III et II du Würm) et non du stade 7 (interglaciaire Mindel-Riss) comme envisagé antérieurement par quelques auteurs.Les 15 âges obtenus se situent entre 10130 ans BP et plus de 48 000 ans. This work has been supported by NOAA and NSF and was the subject of M. thesis work by Margaret Rafter and Hillary Sletten. More recent collaboration has been with Juan Ramon Vidal-Romani and his colleagues at the University of La Coruna in northwestern Spain and with Fuyuan Liang of Western Illinois University. student James Baldini's thesis focused on relationships between drip rates and speleothem morphologies, and Joe Elkins's Ph. work investigated ways to extract more meaningful carbon isotopic compositions from speleothems.

Much of this work has been done in collaboration with Dr. Brook of the UGA Geography Department, and it has focused on stalagmites from southern Africa, the southwestern United States, China, India, and Belize. student Ny Riavo Gilbertinie Voarintsoa has now joined this effort too.

These revealed that there were reversals and inconsistencies along single horizons, and it was found that carbonate fragments in cores of nodules gave older dates; also some recrystallization of carbonate had taken place and more than one generation of micrite was present.

Dates from soil carbonates in the arid zone are not reliable estimates of the age of pedogenesis, but can be useful if their limitations are recognized.
