[Piper Diagram Zoom]

The data I am plotting in a piper diagram are all Na-Cl water types and are clustered on top of each other.  Is there a way that I can zoom into a portion of the piper diagram enabling me to differentiate between samples?

[Trace element addition to mineral phases (water-rock interaction)]

I am trying to simulate water quality of runoff and seepage from a waste rock dump.

I currently have the mineralogy from XRD analysis and trace element concentrations of waste rock.

 

I would like to determine the chemistry resulting from the interaction of rain with for example; Rhyodacite or Andesite.

 

I have entered the Basis solution along with the kinetic reactants (minerals present as per XRD results) however would like to know how to incorporate additional trace elements.

 

For example the mineral phases present include;

Quartz

Anorthite

Calcite

Anatase

Pyrite

Kaolinite

Montmorillonite.

 

How can I include trace quanities of As, Pb, Ni, V ect?

 

Thank you for your help
