Reasons from Gibbs free energy minimization, the phase rule, and protolith-specific facies assemblages through petrography, EPMA/LA-ICP-MS microanalysis, pseudosections (Perple_X, THERMOCALC, MELTS), and classical thermobarometry while treating retrograde overprinting, serpentinization, propylitic alteration mimicking grade, and EPMA analytical scatter mistaken for P-T trends as first-class failure modes.
