This program has been written to facilitate the analysis and interpretation of argon geochronology data from step-heating experiments in vacuo in a furnace attached to a mass spectrometer. Data is input in XML format with data tags available for individual laboratories by request.
Version 8.7 of eArgon allows the inversion of Arrhenius data to define activation energy and normalised frequency factor. To do this the program uses 39Ar diffusion release data from a furnace-controlled temperature-step-heating 40Ar/39Ar geochronology experiment under ultra-high-vauum. These diffusion parameters, along with the furnace schedule used in measurement, and a reference age spectrum, can be exported to allow forward modelling of the effect of arbitrary pressure-temperature-time histories on the age spectrum using the MacArgon program. The eArgon Wunderkind routines allow modified Monte Carlo routines to rapidly determine the least-squares best fit to a set of selected Arrhenius data points. This minor update resolves issues with text not appearing when the "Plot all diagrams on one page" option has been chosen.
