Tutorials

The tutorials below show how you can use The Geochemist's Workbench to quickly solve a variety of problems in geochemistry. Click on an image to launch the corresponding tutorial.

If you have installed the GWB software, click on the icon shown underneath each diagram to open the app pre-configured to calculate the diagram shown. (If two or more GWB icons appear, save all files to your desktop, then double-click on the first.)

Be sure to check out as well our collection of YouTube videos of the techniques shown in the tutorials below.

An expanded set of tutorials covering Reaction Path Modeling and Reactive Transport Modeling are available on the main GWB website.
