CosmoCalc is an Excel add-in (.xla) for cosmogenic nuclide calculations. The program scales production rates for 10Be, 26Al, 21Ne, 3He and 14C within a self-consistent framework of calibration sites; calculates exposure ages, erosion rates and burial ages; includes a forward modelling calculator, and generates 21Ne/10Be and 26Al/10Be two-nuclide diagrams. | ||

RadialPlotter is a user-friendly application for generating radial plots. It has the following advantages over existing programs such as Trackkey or MacTrack. (1) The main purpose of the program is to produce radial plots. Therefore, radial plot functions are not buried deep inside the menu structure and the interface is very straightforward. (2) RadialPlotter was written in Java (version 6) and is, therefore, perfectly platform independent. (3) In addition to fission track radial plots, RadialPlotter also offers the possibility to generate radial plots for luminescence dating, or any other kind of data such as (U-Th)/He or U-Pb ages. | ||

DensityPlotter produces publication-ready kernel density estimates, probability density plots, histograms, radial plots and mixture models of (detrital) age distributions. The program is based on, and in fact offers exactly the same functionality as RadialPlotter albeit with a different set of pre-loaded preferences. | ||

HelioPlot implements the following functionality. (1) Plots (U-Th)/He and (U-Th-Sm)/He data on ternary diagrams and logratio plots. (2) Calculates central ages, which are the most accurate estimators of average age. (3) Computes 95% confidence intervals using a deterministic Bayesian algorithm. (4) Calculates MSWDs indicating goodness of fit by a single logistic normal population. (5) Saves the output in image (.png) or vector (.pdf) formats. | ||

MuDiSc is a Matlab GUI implementing Multi-Dimensional Scaling (MDS) analysis in the context of detrital geochronology. Given a table of pairwise 'dissimilarities' between samples, MDS produces a 'map' of points on which 'similar' samples cluster closely together, and 'dissimilar' samples plot far apart. MuDiSc uses the effect size of the two-sample Kolmogorov-Smirnov statistic as a dissimilarity metric. | ||

geochron@home is a crowd-sourcing app for fission track dating. It can be run in a web browser, on your computer, tablet or smartphone. It is based on the notion that human observers are better at pattern recognition than computers, and that groups of human observers are better at counting items than individual observers. Please give the app a spin and if you register with your email address (optional), we will notify you of and acknowledge you in any publication resulting from your work. | ||

Xenarthra is effectively blank correction software. It can take any number of isotopes (as long as they have an associated uncertainty) and blank correct. Any number of samples can be corrected for any number of blanks in one go. Once blank correction has been applied, Xenarthra can then correct the data. With 4He-3He data it will simply calculate the ratio of the 4He-3He inputs. With 40Ar-39Ar data it will correct for mass discrimination, isotope decay, interferences etc. The user can select whether to use the "old" or "new" decay constants. |
