It was found that artefacts of varying ages have hydration rinds of very similar overall thickness and that the relationship between the theoretical and actual character of the diffusion front is more complex than is widely assumed.
Archaeologists make inferences about past human behaviour based on patterned material residues in various sedimentary contexts, including existing landsurfaces.
The science of geochronology is the prime tool used in the discipline of chronostratigraphy, which attempts to derive absolute age dates for all fossil assemblages and determine the geologic history of the Earth and extraterrestrial bodies.
By measuring the amount of Radioactive decay of a radioactive isotope with a known half-life, geologists can establish the absolute age of the parent material.These deposits are generated by processes that may obscure some observational scales while highlighting others, and interpretive differences may arise from a lack of explicit models of deposit formation.Here, an exploratory agent-based model based on the concept of the palimpsest is used to examine the effects of episodic sediment transport on the visibility and preservation of surface archaeological deposits in a fluvial context.Outcomes from the model indicate that the compound influences of preservation and visibility are capable of transforming a static radiocarbon record into one of increasing intensity toward the present, while simultaneously displaying periodic chronological gaps - features that have been used in our Australia study area to argue for demographic change driven by social or environmental factors.To differentiate between interpretations, expectations derived from the model are assessed against a second proxy from the same study area, namely optically-stimulated luminescence dates from hearth stones in surface contexts.Note: Many of our articles have direct quotes from sources you can cite, within the Wikipedia article! A variety of dating methods are used by geologists to achieve this.
