You can easily import geochronology data from any published (or unpublished) article by using a csv (comma-separated values) template
. Here is how you do it:
- Download the template
- Open it with any spreadsheet software (e.g., MS Excel).
- Fill out the required columns:
- Analysis#. Make sure that sample number is separated from analysis number by one of the four symbols: comma(,), dot (.), underscore (_), or dash (-).
- 207Pb/235U and its uncertainty
- 206Pb/238U and its uncertainty
- 207Pb/206Pb and its uncertainty
- Fill out the optional columns. If data for them is not available, fill each cell with '-1' (discard the quote mark)
- Make sure not to erase the "Dezirteer_template" in the first row.
- When saving, make sure to save in the same .csv format (ignore the warnings that Excel scares you with).
- The file is ready for import!
- The easiest (and highly recommended) way is to export all channels from Iolite.
- The absolute necessary channels are:
- Final206_238; Final206_238_Int2SE
- Final207_235; Final207_235_Int2SE
- Final208_232; Final208_232_Int2SE
- Final207_206; Final207_206_Int2SE
- It is of great benefit if you export both (required) internal and (highly desired) propagated uncertainties.
- Having channels with 204Pb in denominator (e.g., Final206_204) will allow Dezirteer to calculate 204Pb-corrected ages (usually not an option for signal measured by Faraday detectors).
- Channel Approx_U_PPM will allow filtering out grains with high uranium contents.
- If there is an error during import, Dezirteer will likely notify, at which analysis the problem happened. Check the file for any irregularities.
