inverse modelling with silicate weathering

[vivek vasudev]

hello, anyone plz tell me phase equation for pyroxene........

llnl.dat has an equation for Ca-Al_Pyroxene.

Note that the master species in llnl.dat is SiO2, whereas most other databases it is H4SiO4. You will need to adjust the equation accordingly if you want to use the equation with another database, say phreeqc.dat or wateq4f.dat. For inverse modeling the log K will not matter.
