NERC Radiocarbon Facility (East Kilbride) The NERC laboratory - NERC Radiocarbon Facility (East Kilbride) - is a central facility for the UK's Natural Environment Research Council (NERC), providing dating support in the environmental sciences.The Laboratory has an "open-door" policy for all existing and potential users of its facilities at all stages of their research projects, and collaboration is strongly encouraged.This article gives an overview of the main model components used in chronological analysis, their mathematical formulation, and examples of how such analyses can be performed using the latest version of the Ox Cal software (v4).Many such models can be put together, in a modular fashion, from simple elements, with defined constraints and groupings.Piperno presents radiocarbon analysis of phytoliths from modern Neotropical plants collected between 19.
In other cases, the commonly used "uniform phase" models might not be appropriate, and ramped, exponential, or normal distributions of events might be more useful.
When considering analyses of these kinds, it is useful to be able run simulations on synthetic data.
In most dating applications, however, we have larger numbers of 14C measurements and we wish to relate those to events in the past.
Bayesian statistics provides a coherent framework in which such analysis can be performed and is becoming a core element in many 14C dating projects.
If radiocarbon measurements are to be used at all for chronological purposes, we have to use statistical methods for calibration.
