Trackkey: a Windows program for calculation and graphical presentation of fission track data

Individual dating of detrital apatite and zircon crystals in arenitic sediments by the fission track method is a useful. promising technique for provenance analysis. The ages form clusters which are characteristic for the main source areas of siliciclastic sediments. The identification of age groups and the comparison of age patterns of sedimentary samples require graphical presentation of the data sets. A Visual Basic program is presented for calculating the main statistical values and plotting the single grain ages. TRACKKEY provides a complete system for data processing for the external detector method using both zeta and activation calibration systems. The plots are linked to each other and they are presented in one window for better overview. The program allows fast and easy selection and grouping of individual data. (C) 2002 Elsevier Science Ltd.
