Experimental Petrology


The experimental petrology community aims to provide a transparent and accessible resource of experimental partitioning data for the community. It now includes the experimental trace element partitioning data from more than 5400 experiments, including the experimental conditions, and the major and trace element composition of the phases

LEPR/traceDs template

The traceDs template was designed to provide structure for the data we produce. The template includes a description of the type and form of the data present in the traceDs database. We recommend that users download the template and read the instructions and readme tab first. Once the basic content is clear, users can read the specific descriptions in the columns for the experimental conditions, liquid, and phase tabs. This will help in gaining an understanding of the data format before one attempts to process the mineral specific spreadsheets available below. The template is also suitable for datasets that can be incorporated in the Library of Experimental Phase Relations (LEPR).

Pre-compiled mineral spreadsheets

Using the traceDs template, we have compiled published experimental data on trace element partitioning. Each spreadsheet contains data for one specific mineral. Please read the description of the database in the traceDs template before you process the information in the spreadsheets.
