Chronological Bayesian Models Integrating Optically Stimulated Luminescence and C-14 Dating


A collection of various R functions for Bayesian analysis of luminescence data and C-14 age estimates. This includes, amongst others, data import, export, application of age and palaeodose models.


This package is based on the functions: Generate_DataFile and Generate_DataFile_MG to import luminescence data. These functions create a list containing all informations to compute age of single-grain OSL measurements for the first function and multi-grain OSL measurements for the second.

The functions: Age_Computation and AgeS_Computation use Bayesian analysis for OSL age estimation for one or various samples according to difference models (e.g. different dose-response curves and different equivalent dose distributions around the palaeodose).

It is possible to consider various BIN/BINX-files per sample, to compute ages of samples in stratigraphic constraints and to integrate systematic errors.

It is possible to calibrate C-14 age with the function AgeC14_Computation. We can also estimate chronology containing 14C age and OSL samples with the function Age_OSLC14.
