Hi,
As mass balance calculations rely on the validity of: 1) the reference
sample and 2) immobile element/-s, these two elements of the mass
balance analysis are critical.
To model elemental fluxes for the alteration zone around gold-bearing
quartz veins, I chose immobile elements by examining the correletion
between elements that are assumed to be immobile during hydrothermal
alteration, such as: Al, Ti, Zr, V, Hf, Nb...very much in the same way
as in Mac Lean and Kranidiotis (1987). In this analysis Al and Ti showed
the strongest correletion.
It would be very interesting to hear about other's experiences of mass
balance analysis and the criteria used for choosing immobile element/-s.
Has anyone used thermodynamic data, available in SUPCRT 92 together with
SEM-work?
Cheers!
Anton
