Hi everyone,
It has been stated in many standerd books and papers that biotite
is formed in the biotite alteration zones of greenstone hosted gold
deposits, by hydration (and carbonation) of amphibole or epidote. As i
understand this has to be a metasomatic reaction involving addition of
K2O. I was trying to write and balance one such reaction involving
amphibole, but not yet got good result (i mean geologically relevent
situation). Is there any suggestion in this regard.
cheers
