A: In the Column Properties dialog make sure that the numeric variables in your dataset are aliased and have a green dot next to them.  Click on the Select Mineral Groups icon on the RHS (Right-Hand Side) Toolbar in an open plot window and make sure there is at least one mineral composition checked to display.  Use the Show/Hide Mineral Compositions icon to display the minerals in the plot window.

A: The chemical composition of each of these minerals is as follows:

Chlorite 1 = Mg5Al2Si3O10(OH)8

Chlorite 2 = Mg6AlSi3O10(OH)8

Chlorite 3 = Fe2.5Mg2.5Al2Si3O10(OH)8

In ioGAS version 4.5, the composition of each of these minerals is displayed when you hover your mouse over the mineral name in the selection window.

Alternatively, to find out what the chemical composition is for these and other minerals displayed in a plot window click on the Show/Hide Mineral Compositions button on the RHS toolbar and it will cycle through displaying abbreviated mineral name, full mineral name and chemical formula for each node.
